Fox Racing Shocks 980-02-058-1 2.0 Factory Series 18in. Emulsion Coilover Shock 7/8in. Shaft Custom Valving Black

The Fox Racing Shocks 980-02-058-1 is a 2.0 Factory Series emulsion coilover shock absorber featuring 18 inches of travel, a 7/8-inch (0.875 in.) shaft diameter, and custom valving in a black finish. This is the universal, rebuildable coilover shock built on Fox's race-proven damping platform, designed for off-road, performance, and competition suspension builds.

The emulsion design integrates oil and gas in a single seamless alloy body, delivering consistent damping performance without the added complexity of a remote reservoir. Custom valving (indicated by the "-1" suffix) means this shock is tuned beyond the standard 50/70 compression/rebound specification — ideal for builders and fabricators who require application-specific damping characteristics.

Sold individually. This shock is designed for dual spring rate setups and accommodates a maximum combined total spring length of 39 inches — typically paired with an 18-inch top spring and a 20-inch bottom spring. The custom valving designation makes this unit well-suited for fabricators building specialized suspension systems or those pairing it with a bypass shock as a coil carrier configuration.
