This is an optional Exotek TLR 22 5.0 Aluminum Rear Hub Set. These heavy duty 7075 rear hubs include precision machined delrin hub height inserts that allow the hinge pin to be set at stock level (+0) or raise the hub in 1mm increments (+1, +2, +3). This is a key tuning aid for matching the adjustable differential height (keeps the axle and bones level the diff height inserts are raised or lowered) and makes it easier to lower your ride height for high grip conditions. These hubs bolt directly to the TLR 22 models with no modification with the base setting matching the stock TLR 22 5.0 geometry.
The 7075-aluminum alloy hub construction with polished black and silver chamfer finish is attractive, with four machined delrin inserts included. In contrast to the previous model the two rearmost ball stud holes have been removed, with only 1g of additional weight added overall.
