Initially developed for our ATV shock conversion kits made in 2004, we set out to develop the best adjustable shock under $250.
Due to popular demand, we have created the DIAMOND+ model shock withadded compression adjustment and a high quality machined body for only $399!
After years of response and improvements, we are happy to provide a shock that can be used on ATVs, Motorcycles, and other off-road vehicles to upgrade stock suspension performance.
Compatible with our Adult ATV Shock Conversion Kits. (Same size as 400ex stock shocks)
These shocks are adjustable in preload, compression, and rebound:
Preloadcan be adjusted using included tool to tighten the nut/collar above spring coils.
Compressioncan be adjusted by twisting the top knob on the reservoir.
Reboundcan be adjusted by twisting the bottom knob on the reservoir.
Spring Rate:
400mm x 9mm Coils:172 lbs/in
