These are cross-over collars from Schmidty Racing Suspensions to convert the OEM, Walker Evans side-by-side shocks into truly adjustable dual rate shocks. These collars will thread right onto the OEM shock body without any shock modification. They allow you to adjust when to transition from both springs being active to where the shock transfers to the lower main spring alone, giving you the secondary spring rate.
Our collars are made of tough co-polymer with tight manufacturing tolerances, to give you second-to-none reliability and "quiet" operation. They also have two (2) stainless steel pinch screws to keep the collar locked in place.
The collars are sold as a Single, Pair, or 4 Piece Kit for the Walker Evans 2.0" front and 2.5" rear shocks found on XP1000, RS-1, and XP1000 Turbo. One (1) cross-over collar needed per shock.
