JM92 Advanced Suspension Fluid 1 Quart

The JM92 Advanced Suspension Fluid 1 Quart from FOX FACTORY INC is engineered for serious enthusiasts and mechanics who demand precision performance from their suspension systems. This premium formulation is specifically designed to maintain optimal damping characteristics across extreme temperature ranges and demanding driving conditions. Whether you're maintaining a high-performance off-road rig, a track-focused vehicle, or a custom build, this fluid is essential for preserving the integrity and responsiveness of FOX Racing Shox components that demand consistent, predictable behavior under stress.

JM92 is formulated to resist viscosity breakdown and maintain stable damping performance in both cold starts and sustained high-heat cycles—critical when pushing suspension through repeated compressions or extended high-speed runs. The advanced fluid chemistry ensures minimal foaming, superior heat dissipation, and consistent pressure response within FOX dampers and accumulators. One quart volume allows for complete fluid refreshes in most FOX Racing Shox shock absorbers or multiple top-up services across a vehicle's suspension system, making this the professional choice for serious rebuild and maintenance work.

This product is essential for owners of FOX-equipped vehicles who perform their own suspension service—including off-road trucks, rally builds, desert racers, and street performance vehicles with coilovers or coil-over conversions. Mechanics and enthusiasts rebuilding FOX shocks or performing mid-life fluid flushes will appreciate the 1-quart format, which balances waste reduction with sufficient volume for complete service intervals. Proper fluid maintenance extends shock service life, restores responsiveness after extended use, and ensures your suspension investment continues delivering the handling precision FOX products are engineered to provide.
