WP Bladder Kit Available for the latest 2023 WP XACT 5057 shock absorbers with the larger reservoir. The WP bladder conversion is designed to reduce the amount of friction generated inside the shock absorber and increase the gas volume inside the reservoir. This product drastically improves compliance on low-speed movements of the rear wheel and makes the shock react more consistently over differing temperature ranges. This bladder kit is a huge advantage in a three-hour hair-scramble race as well as that extra edge needed on a beat down motocross track! ZF10011 Fitment: Stock Shock only.
