Traxxas Slash 4×4 Upgrades

Posted by AParsons on February 20, 2014

Slash 4x4

The Traxxas Slash 4×4 is one of the most popular and vesitile RC vehicles on the market. The Slash 4×4 is a solid and reliable machine with Traxxas offering some of the best customer support in the business. Due to its popularity, the aftermarket parts availible for this RC vehicle are countless. You could build a Slash 4×4 and not have a single Traxxas part on it. We are going to focus on some of the more popular upgrades.

Things to consider when you are upgrading your vehicle:

– Aluminum is durable, looks great and it comes in wide variety of colours, but it is expensive and will add weight to your vehicle.

– Not all aluminum is created equal, some products are better than others. Do your research.

– Do not under estimate the strength and durability of the plastic RPM or Pro-Line parts.

– It is easy to go overboard, remember your budget.

– Consider upgrading parts only as you break them. That helps to ensure you don’t upgrade unnecessary parts.

– Shop around for prices and support your LHS but also check out online retailers like TheToyz, DollarHobbyz, Amainhobbies, Towerhobbies and Horizon Hobby just to name a few. All of these parts can be found for less than the MSRP.

-A-Arms-

A-Arms are upgraded to give your truck a little extra durability and stiffen the suspension. The thing to remember is that you still want something that has some flex to it. If you were to upgrade to Aluminum A-Arms and have an impact that would break a plastic A-Arm, you risk transferring the damage to a more expensive part on your truck and bending your Aluminum A-Arm beyond repair. Damage usually occurs at the weak point. You can’t go wrong with a simple RPM A-Arm upgrade (You may need to scroll down when directed to the RPM Site.)

RPM A-Arms

RPM A-Arms

RPM A-Arms come in 3 different colours. Black (Part# 80702), Blue (Part# 80705)  and Green (Part# 80704) . Front and Rear A-Arms are the same Part# for the Slash 4×4

proline

Pro-Line ProTrac 4×4 A-Arms

Pro-Line make a quality A-Arm. The ProTrac 4×4 A-Arm is Pro-Line Part# 6082-01 and is a direct replacement for the stock part.

STRC Aluminum A-Arms

STRC Aluminum A-Arms

A-Arms can also be found in Aluminum from STRC, Golden Horizons, Hot Racing and others. Just look around and ask questions, read reviews to ensure proper fit and durability.

-Bearing Carriers & Caster Blocks-

If you do any kind of driving you will eventually break your Bearing Carriers and/or Caster Blocks. The carriers and blocks can be found as either plastic or aluminum. My personal preference is aluminum on all four corners, but if you want to save some money, I recommend to just use Aluminum on the Front end. A less expensive solution would be to go with the plastic RPM or Pro-Line on the corners.

6832X-aluminum-C-hub_6804L-6807L

Traxxas Aluminum Bearing Carrier and Caster Blocks

Traxxas Front Aluminum Bearing Carriers, Part# TRA6837x and Caster Blocks Part# TRA6832X, offer durabilty and some bling. For the Rear you will need Part# TRA1952X

ST1952-5B

STRC Rear Bearing Carrier

STRC also make Front Aluminum Bearing Carriers Part# ST6837B and Caster Blocks Part# ST6832B. For the Rear you will need Part# ST1952-5B. Available in a variety of colours.

Plastic Carriers

rpm caster

RPM Caster Blocks & Spindle Blocks

You could go RPM on all four corners which would really save you money for other things and  you shouldn’t have a problem. For the front you need RPM Part# 73592 (Scroll down) and for the rear you need Part# 80732 (Scroll down).

Pro-line ProTrac Rear Hub Carriers

Pro-line ProTrac Rear Hub Carriers

The Pro-Line PRO-2 Front Hub Part# 6101-01 and the Pro-line ProTrac Rear Hub Carriers Part# 6062-05 are also excellent upgrades and provide more setup options over the stock part.

-CVD’s-

The Traxxas stock plastic CVDs wear out quickly. You will get play in the wheels and the slider design will eventually seize up. This can be overcome by sanding the CVD, but many people choose to upgrade the CVD when it comes time to replace them. These upgrades require little to no maintenance and add durability.

Traxxas Front Heavy Duty Steel CV Driveshaft

Traxxas Front Heavy Duty Steel CV Driveshaft

The Traxxas CVD upgrade is a direct replacement. For the front you need Part# TRA6851R and Part# TRA6852R for the rear.

Tekno M6 Driveshafts and Steering Blocks for Slash 4x4

Tekno M6 Driveshafts and Steering Blocks for Slash 4×4

The Tekno RC option will require you to change your bearing carriers in the front and rear, but the Tekno RC kit comes with the needed carriers and bearings. Front Part# TKR6851X and the Rear is Part# TKR6852X.

Tekno has you covered if you happen to be using the Pro-line ProTrac Suspension Kit. For the Front you need Part# TKR6851PL and for the Rear look for part# TKR6852PL.

MIP X-Duty CVD's

MIP X-Duty CVD’s

M.I.P. have 3 different styles; the first one is the MIP X-Duty CVD Kit with keyed axles, it most closely matches the slider style CVD found in the stock setup. Front is MIP Part# 10132 and the Rear is Part# 10130. This is a beefy product and is great if you are hard on your vehicle.

MIP Aluminum Race Duty CVD

MIP Aluminum Race Duty CVD

You can get the M.I.P. Race Duty CVD as either aluminum or steel. For the Front Aluminum Race Duty CVD use MIP Part# 13105 and for the Rear Part# 13115. For the steel CVD’s use Part# 13260 for the front and Part# 13270 for the rear. The Steel CVD will be tougher then the Aluminum, but it will add weight to your vehicle. This is something that should be considered if your a racer or a basher or something in between.

-Motor Mount-

I would consider this the weak spot on the Slash 4×4. The Traxxas design features a 10mm x 15mm x 4mm bearing which will soon seize up and cause damage to your truck (If you use your Slash off-road or expose it to water), the bearing seems to simply be too small for its intended purpose. If you stay with the stock setup, get extra bearings and check this bearing often and swap it out when you notice it begin to seize up.

King Headz LCG Motor Mount

King Headz Rally Chassis Motor Mount

There are different Motor Mounts on the market, but King Headz offer what is arguably the best alternative. The Aluminum Mount has a oversized 10mm X 19mm X 5mm bearing and a place to mount telemetry. Part# 6860T for the HCG Chassis (Regular Chassis) and Part# 7460 for the LCG Chassis (Rally Chassis).

King Headz Slipper Bearing Adapter

King Headz Slipper Bearing Adapter

If your Slipper Bearing Adapter happens to be plastic, do yourself a favour and pick up the King Headz one as well. The stock plastic part will melt if the Motor Mount Bearing seizes and this can cause serious damage. Part# 6893.

-Shocks-

Shocks are upgraded in order to gain better handling, cleaner landing of jumps and improved responsiveness. If you want to upgrade your shocks, watch your budget. If you want to save money, many people have had good results with the Traxxas Ultra Shocks, by using aluminum shock caps and changing to Losi Springs.

Traxxas Big Bore Shocks

Traxxas Big Bore Shocks

The Traxxas Big Bore Shocks can be a nice upgrade over the Traxxas Ultra Shock, but don’t seem to hold as much shock oil as the Traxxas Ultra Shock. They do work nicely when dialed in, but if you plan on using a heavier than stock battery, motor or ESC, you should consider upgrading to a different shock. The Traxxas Big Bores seem to be close to their limit with the weight of the Slash 4×4. The complete set can be found with Part# TRA5862

Traxxas GTR Shocks

Traxxas GTR Shocks

The Traxxas GTR Shocks are fairly new on the market and feature a threaded shock body which allows for quick and easy spring adjustment. The reviews for these shocks has been very positive. For the Front use Part# TRA7461x and for the Rear use Part# TRA7462x.

Proline Power Strokes

Pro-Line Power Strokes Shocks

The Pro-Line Power Stroke feature dual springs for added fine tuning but can leave a pretty big dent in your wallet. They are loved by many in the RC community. For the Front use Pro-Line Part# 6063-00 and for the Rear use Part# 6063-01.

Pro-Line Pro-Spec Shock

Pro-Line Pro-Spec Shocks

The Pro-Line Pro-Spec is the next generation of Pro-Line Shock Technology and feature a bleeder screw in the shock cap. Once again these will leave a dent in your wallet, but many people swear by them. For the Front use Part# 6308-00 and for the Rear use Part# 6308-01.

Losi SCTE Shocks

Losi SCTE Shocks

Losi SCTE Shocks – These are a big shock that will reduce body sag and help with handling. You can find these shocks by searching “Losi SCTE Shocks” on eBay or Google. You can also build these yourself, see the parts list below. You may find that these shocks leave your Slash slightly higher in the back end.

1 x STLB2825R STRC CNC Machined Aluminum Front Shock Body Set (Red is the colour used for this post but there are other colors available)
1 x  STLB2826R STRC CNC Machined Aluminum Rear Shock Body Set (Red)
1 x LOSB2904 Losi Front & Rear Shock Plastics & Ball Set (4)

1 x LOSB2845 Losi Front & Rear Shock Shaft Set (4)
2 x LOSB2906 Losi Shock Rebuild Set (2)

The last two pieces aren’t really necessary, they just add some style points.

1 x STLB2904R STRC CNC Machined Aluminum Shock Cap Set (Red) – Shock Caps already come with Part# LOSB2904
1 x LOSB2905 Losi Front & Rear Shock Boots (8) – These will eventually rip, fall apart and need to be replaced.

-Shock Towers-

Shock Towers are replaced to take unwanted flex out of the suspension, which in theory gives you a more percise feel and handling for the vehicle. Different Shock Towers can also offer more setup options. I have used the same RPM shock towers for the last 3 years and I have heard arguments for both plastic and aluminum. If I ever break my RPM shock tower, I will upgrade to aluminum.

STRC Rear Shock Tower

STRC Rear Shock Tower

STRC make some of the best aluminum shock towers on the market. They come in a variety of colours, just make sure you get one for the front and one for the rear.

Blue: Front Part# ST6839B  and for the rear you need Part# ST6830B.

Gun Metal: Front Part# ST6839GM  and for the rear you need Part# ST6830GM.

Red: Front Part# ST6839R  and for the rear you need Part# ST6830R.

Silver: Front Part# ST6839S  and for the rear you need Part# ST6830S.

RPM Shock Tower

RPM Shock Tower

RPM make a very reliable plastic shock tower. Front Part# 70392  and for the Rear you need Part# 70362.

TRCE Shock Tower

TRCE shock towers

The Team RCE Shock Towers are made of aluminum and feature multiple adjustments. For the Front you need Part# SL44-FST and for the Rear you need Part# SL44-RST.

You can also find Aluminum Shock Towers made by companies like Traxxas and Integy.

-Bumpers-

Tradionally bumpers are done for esthetic purposes. The Traxxas bumpers work great and issues with them are few and far between.

RPM Front Bumper

RPM Front Bumper

RPM make a replacement Black Front Bumper & Skid Plate Part# 80022. Chrome Front Bumper & Skid Plate Part# 80023. Blue Front Bumper & Skid Plate Part# 80025.

RPM Rear Bumper

RPM Rear Bumper

RPM also make Rear Bumpers in the same colours. Black Rear Bumper & Skid Plate Part# 80122. Chrome Rear Bumper & Skid Plate Part# 80123. Blue Rear Bumper & Skid Plate Part# 80125.

 -Chassis-

Team RCE LCG

Team RCE LCG

Traxxas Slash 4×4 LCG options were discussed in a previous post and can be found by clicking on Traxxas Slash 4×4 LCG Chassis Options.

-Nerf Bars-

Personally I like Nerf Bars, but some people don’t even use them. When the stock Nerf Bars eventually break, upgrade to RPM.

RPM Nerf Bars

RPM Nerf Bars

RPM Black Nerf Bars, Part# 80622. Blue Nerf Bars, Part# 80625.

-Tires-

JConcepts Chopper Tire

JConcepts Chopper Tire

Upgrading from the Stock Tires will increase grip and handling. There is a huge selection of Tires available for the Slash 4×4. Get a Tire based on how you use your truck as there is a big difference between a Clay Surface Racing Tire and a Sand Paddle Tire. To help you get the Tire best suited for your needs check out the Pro-Line Application Guides, the JConcepts Tire Guide or the AKA Tire Application Charts.

– Any Short Course Truck Tire will fit as long as it matches the industry standard 2.2″/3″ bead sizes.

– You can get Tires by themselves or already mounted on wheels.

– Tires come in different compunds. A racer may like a super soft compound and a basher may perfer a medium compound. A Soft Tire compound will wear quicker than a medium compound Tire, but provide better traction.

Here are a few all purpose Tires from some of the big manufactures. Pro-Line Caliber, JConcepts Chopper and AKA City Block 2.

 -Wheels-

Pro-Line Bead-Loc Wheel

Pro-Line Bead-Loc Wheels

The selection of Wheels available for the Slash 4×4 is almost as massive as the Tire selction. I can’t say one Wheel is better than the other, so just get something you like from a reputable company and you should be fine.

– You can get Bead-Loc Wheels, which means no glue for the Tires, because they are held in place with a removable ring.

– Bead-Locs are not recommended for the high speeds that brushless motors can provide.

You find the same major players for Wheels as we had for Tires Proline, JConcepts and AKA.

 -Body Mount-

You might want to change these because you don’t like body clips or maybe you are doing a custom build and want to add some clearance between the body and wheels. You are pretty limited as far as Body Mounts are concerned. After the stock option you will find the popular choices are:

RPM Adjustable Height Body Mounts

RPM Adjustable Height Body Mounts

RPM Adjustable Height Body Mounts. This set comes with spacers that give you a couple of height options. RPM Part# 73932.

Pro-Line Extended Body Mounts. Slash 4x4

Pro-Line Extended Body Mounts. Slash 4×4

Pro-Line has an Extended Body Mount Kit that gives you multiple height adjustments and instead of body clips the Pro-Line option has a twist-on body securing method. Part# 6087-00. If you go with this option also consider the Pro-Line Secure-Loc Cap Replacement Kit. Part# 6070-02, just like body clips, it is good to have extra caps.

-Servos-

Servos are usually upgraded after you strip the plastic gears in the Traxxas servo. You have the option to rebuild your stock servo with a relatively inexpensive rebuild kit, Traxxas Part# TRA2072. You can buy another stock servo Part # TRA2075 or you can consider a metal geared servo. Don’t worry too much about a waterproof servo. They are easy to waterproof yourself with plenty of tutorials available on YouTube.

Hitec HS-5645MG

Hitec HS-5645MG

The Hitec HS-5645MG Digital High Torque Metal Gear Servo is a reliable metal geared servo which will bolt right up. It has a price point that should be considered if you are thinking of buying another stock servo instead of rebuilding. Part# HRC35645S.

Savox SC-1258TG

Savox SC-1258TG

The Savox SC-1258TG Super Speed Titanium Geared Digital Servo is an expensive alternative compared to the stock servo and the Hitec but it is highly respected in the RC community and many consider it bullet proof. It will also bolt right up. Part# SAVSC1258TG.

That is just two of the many servos options out there. Use the Servo Database to compare the stock servo with the one that you are considering to ensure you get what you want.

 -Motor and ESC Combinations-

There are countless options and combos for Motors and ESC’s and I am not going to get into all of them. I will give some guidance so you can properly select your own combo. I will also include a few of popular combinations that are considered upgrades to the Venelion system.

First, a few Basic things to remember when ESC shopping:

– Get an ESC that can handle the battery you want to run. If you want to use 6s Lipo, make sure the ESC can handle it.

– If you want a waterproof ESC get one. If you don’t, you can waterproof it yourself (See YouTube), but that will void your warranty.

Sensored vs Sensorless Motors

Sensored motors can offer more timing options than sensorless and take timing measurements via hardwire sensors. They are also smoother and traditionally more expensive. Racers tend to use sensored motors.

Sensorless motors take timing measurements via software. At slower speeds, the sensorless motors are prone to cogging. Not something for a crawler setup, but shouldn’t be a problem if you are a normal average user.

Find a KV Rating that suites you

The lower the kv rating means the higher the torque, which gives a lower speed, but will allow you to use higher gearing. (Think Crawlers)

The higher the kv rating means the less torque, which gives a higher speed, but you will need to lower the gearing.(Think Speed Runs)

Common Motor ESC Combinations:

Hobby Wing EZRUN WP SC Combo

Hobby Wing EZRUN WP SC Combo

The HobbyWing EZRUN WP SC Combo is popular due to its price, reliability and waterproof ESC. The ESC will allow for variety of motor and battery combinations and the Hobbywing combo includes a LED Program Card. These combos can be found on eBay or at Hobbypartz.

 

Castle Creations Sidewinder 3

Castle Creations Sidewinder 3

The Sidewinder 3 is a waterproof Motor and ESC from a proven and reliable company in Castle Creations.  This combination is programmable as well, but you need to buy a the Castle Link USB adapter which is sold separately.

If you want more info on Motors and ESC’s, then Squirrelod has you covered. He is a well respected member of the RC community and has helped many people with his numerous videos.
