Valve Shim Kit

The FOX FACTORY INC Valve Shim Kit (SKU FOX803-01-024) is a precision valving component designed for Fox Track shock absorber systems. This kit serves riders and off-road enthusiasts who need to fine-tune damping characteristics on their suspension, whether for trail refinement, competition use, or ride quality optimization. Valve shim kits are essential for custom shock tuning, allowing users to adjust compression and rebound damping curves without replacing entire shock assemblies.

This valve shim kit operates by modifying internal damping valve stack geometry, which controls oil flow rates through the shock's piston during compression and rebound cycles. Shims—thin, precision-engineered discs—change the stiffness and engagement point of the valve stack, directly affecting how the suspension responds to terrain input. FOX FACTORY manufactures these kits to exacting tolerances, ensuring consistent performance across repeated cycles and maintaining the reliability expected from factory-level suspension components. The kit's compact packaging (9.2 x 4.8 x 13.5 inches, 2.92 lbs) allows for practical storage and transport to service locations or race venues.

Suspension technicians, track-focused riders, and serious enthusiasts benefit most from this valve shim kit when pursuing incremental damping improvements on Fox Track shocks. Installation requires knowledge of shock internal geometry and fluid mechanics; professional shock service is recommended to ensure proper assembly and tuning results. Compatible exclusively with Fox Track shock platforms, this kit enables custom valving configurations that factory presets may not provide, making it invaluable for competitive or specialized riding applications requiring precision damping control.
