Avid caged diff thrust bearings
Associated and TLR owners can upgrade their diff with an Avid caged diff thrust bearing. The Avid caged bearings make working on your diff much easier, and you don’t have to stress out about losing one of those tiny thrust balls. You also won’t have to get your hands covered in black grease to build the thrust assembly. Avid offers 3 types of diff thrust for varying levels of cost, maintenance, and performance. Tungsten Carbide balls are more true in size and harder than steel, so they are smoother and last longer, but diff setting is still relatively easy. Ceramic balls are completely smooth and the hardest material they offer. This makes for the smoothest feeling, but the diff setting is the most narrow window of adjustment. Steel balls are the least expensive and easiest to set the diff. They do not stay smooth for as long as Tungsten Carbide or Ceramic so there is a small drop in performance for the lower price. Fits all B4.2, T4.2, SC10.2, SC10B and previous models along with TLR 22, 22T, 22 SCT.
