These replacement pre-load collars are thick and made from 6061 billet aluminum. They are ready for race abuse and make pre-load adjustments much easier. These replace the two (2) OEM toothed, upper pre-load collars on each shock. We designed these collars to use a positive connection "pin" style spanner wrench to make adjustments so our collars will not get all chewed up over time.
On many machines the area needed for a spanner wrench to make any adjustments is very narrow and using a typical "hook" style spanner wrench is extremely difficult if not impossible. Our pin style spanner wrenches will not slip off, making them more effective than their counterpart. Simply loosen the stainless pinch bolt and use our pin spanner wrench to adjust the pre-load setting, then re-tighten the pinch-bolt. (You will not find these collars anywhere else.)
These will fit the OEM, aluminum bodied, Fox Podium / Performance series shocks found on Polaris, Yamaha, Can-Am, Kawasaki, and other brands. These collars will thread right onto the OEM shock body without any shock modification.
