FOX Factory Race Series 2.5-Inch Remote Reservoir Coilover Shock Set with DSC Adjusters, Part 880-06-420

Developed from our off-road race shocks, FOX Factory Race Series combines race-proven technology with new, cutting-edge features to provide enhanced ride-quality and winning damping performance you can bolt onto your truck or SUV. Application specific valving to maximize performance. 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.

Upgrade the suspension performance of your 2000–2003 Toyota Tundra with the FOX Factory Race Series remote reservoir coilover shock set, part number 880-06-420. Developed from FOX off-road race shocks, this vehicle-specific system delivers race-proven damping performance, improved ride quality, and precise suspension control. The set is designed for applications requiring an upper control arm and features a black anodized finish for durable, professional-grade performance.

FOX internal bypass technology controls oil flow through multiple zones of the shock stroke, helping provide smooth operation over smaller impacts while delivering increased support during aggressive compression events. The integrated ride zone combines a race-developed piston, internal bypass design, and Dual Speed Compression adjustment, allowing the damping characteristics to be tuned for vehicle weight, terrain, and driving speed. The external reservoir helps dissipate heat quickly for more consistent performance during demanding off-road use.

Built for harsh environments, the FOX Factory Race Series coilover shocks use durable aluminum components, heat-treated spherical bearings with Teflon-lined surfaces, and a seamless alloy body with zinc plating. A redundant sealing system helps promote long-lasting reliability, while the 7/8-inch shock shafts provide strength for demanding trail and performance applications. The shocks are fully serviceable and tunable, allowing maintenance and future adjustments to help extend their useful life. This set fits select 2000, 2001, 2002, and 2003 Toyota Tundra models; verify vehicle configuration and required upper control arm compatibility before installation.
