Avid RC is taking a huge round of applause from Associated and TLR owners. Those small, loose, steel balls that fall everywhere and leave you covered in grease during the rebuilding process of your diff, can now be replaced with the Associated/TLR Diff Thrust Bearing. This product will Fit all B4.2, T4.2, SC10.2, SC10B as well as the TLR 22, 22T and the 22 SCT. This one piece solution to the multi-ball nightmare is available in 3 different types and will make rebuilding your diff a breeze.
Avid has laid out the advantages to each type:
Steel ball: least expensive and easy to adjust the diff. However you will have to replace them more often and the diff will never be as smooth as a Tungsten Carbide or Ceramic ball version. Retails for $3.00
Tungsten Carbide ball: this is what we recommend for most racers, the balls are more true than steel balls and slightly harder but still have a few imperfections which allows the ball to grab the surface of the grooved rings easily. This makes it easy to set the diff tightness. Retails for $10.00
Ceramic ball: these balls are completely smooth and very hard. This makes for the best feeling diff out of all our options but it also makes for the most narrow window for setting your diff tightness correctly. Should only be used by the most experienced of racers. Retails for $10.00
I have been a casual observer of Avid for a while, I have heard and read great things about their bearings. I have had my eye on the Avid TLR Aluminum Topshaft Kit & Triad Slipper for some time and I think it is time for me to get some hands on experience with some Avid products. I just ordered a few of the Steel Thrust Bearings and the Aluminum Topshaft kit for my TLR 22SCT. As usual I will keep you informed.
