Our friend Paul over at Bare Knuckle Chopper Parts makes another GREAT solution to the terrible stock axle adjusters.

First, they use their tried and true axle adjustment plates, which will eliminate the distortion and failure of the stock steel plates offered. Then they made a pair of adjustment blocks that occupy the entire space inside your swingarm, eliminating wall crush and vertical movement. Also, BK uses a roll-formed SS Stud for adjustment, which terminates two issues compared to using bolts for adjustment; first, the stud is locked into the block, leaving no room for thread damage inside the block. Second, the use of a Nylock on the stud “locks” the nut into place, keeping your adjustment exactly where you want it, and no more lost fasteners! And last, of all, we beefed up the stud size to 3/8-24, as opposed to the stock 5/16″ thread. These are unbreakable! You’ll never have adjustment problems or adjustment area damage ever again. Adjustment blocks are black oxide coated, while the adjustment plates are beautifully black anodized, then laser engraved with either the FXR logo or the American Flag.
