FOX Factory Race Series GEN2 2-Inch Universal Front Bump Stop IFP, Threaded Body – FOX983-02-170

Developed in racing and refined for everyday use, FOX Factory Race Series bumpstops are the perfect addition to any aggressive offroad build, working together with your FOX shocks to create the feel of near bottomless travel. Rebuildable and serviceable. Uncompromised performance through FOX’s patented internal bypass technology delivers the feel of near-endless suspension travel. Exclusive internal bypass technology allows oil to flow around the piston at some points of the stroke – while creating humongous pressure at other points – supporting the vehicle like no other product can. Floating through terrain is accomplished with FOX’s ride zone – combining a race-developed shock piston, internal bypass and Dual Speed Compression adjustment – allowing fine tuning for weight, terrain and speed. Dominate any terrain with the brute strength of 3- and 2.5-inch aluminum bodies, cactus cooler reservoirs and 7/8” shafts with redundant seals, all proven in the harshest of environments under the toughest of conditions.

Brief Description: The FOX Factory Race Series GEN2 universal front bump stop is designed for aggressive off-road vehicles that demand controlled suspension performance near the end of travel. Developed through racing and refined for everyday use, the FOX983-02-170 works with FOX shock technology to help absorb hard impacts while maintaining predictable vehicle control. Its threaded body, internal floating piston (IFP), and rebuildable design make it a durable and tunable addition to demanding suspension builds.

Patented internal bypass technology manages oil flow through different portions of the stroke, helping provide progressive support as the suspension approaches compression limits. FOX ride-zone technology combines a race-developed piston, internal bypass control, and suspension tuning capability to help tailor performance for vehicle weight, terrain, and driving speed. The aluminum construction helps dissipate heat quickly, while the hard-chromed 4130 alloy steel shaft and redundant sealing system support dependable performance in harsh off-road environments.

The FOX Factory Race Series GEN2 bump stop is serviceable and rebuildable for extended product life. It includes a replaceable Delrin bump strike pad for quieter operation and durable impact control. Black-anodized CNC-machined aluminum components, FOX Racing Oil, and a high-pressure nitrogen system separated by the IFP contribute to consistent performance. This universal front bump stop is intended for custom installation and should be selected according to the vehicle’s suspension design, available mounting space, and required stroke.

Fitment: Universal front application; vehicle-specific fitment and installation requirements should be confirmed before purchase.
