FOX Factory Race Series 3.2 Internal Bypass Rear Shock for Toyota 4Runner and Land Cruiser GX550 by FOX Part #883-26-169

FOX Factory Race Series 3.2 Internal Bypass shocks for the LC250, GX550, and 4Runner chassis deliver velocity and position-sensitive damping technology, Dual Speed Compression Evolution (DSC EVO) adjustment, and high-speed ready performance in a bolt-on kit. Patented Internal Bypass technology allows for multiple zones of damping control. The result is a comfortable, confident ride with increased damping force through rough terrain. Internal bypass shocks produce more force progressively to control hard bottom-outs, prevent harsh top-outs, and provide an initial catch for landing. Shock fluid bypasses the main piston through bleed holes in the ride zone. As the shock extends past the ride zone in rebound or compression, the bleed holes terminate, forcing fluid through the main piston. Type II anodization prevents corrosion and wear of the 3.2-inch diameter aluminum bodies. Finned reservoirs increase oil capacity, house an IFP, and feature a DSC EVO adjuster. DSC EVO utilizes Variable Valve Control (VVC) on the high-speed circuit. VVC doesn't add preload to the shim stack to adjust high-speed damping. The result is more comfort, independent high and low-speed circuits, and increased capacity for big hits. Add clicks of high-speed compression without sacrificing small-bump sensitivity. FOX 3.2 shocks with Internal Bypass provide the support, adjustment, and confidence you need while driving at speed. Experience race-bred performance next time you leave the pavement. 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.

• Application-specific springs and vehicle-specific tuning maximizes performance.
• Position- and velocity-sensitive damping maximize control through any terrain.
• Patented, internal bypass design Finned remote reservoir with DSC EVO adjuster
• 3.2" impact-extruded and CNC-machined 6061-T6 Type II anodized aluminum body
• Redundant sealing pack system: main seal, wiper seal, scraper seal
• 7/8" hard chromed steel shafts

The FOX Factory Race Series 3.2 Internal Bypass rear shock is engineered specifically for Toyota 4Runner models from 2025+ and Land Cruiser GX550 2024+ with a 0-1.5 inch lift. Designed to deliver race-level performance, this shock features advanced velocity and position-sensitive damping technology that adapts seamlessly to varying terrain conditions. The internally bypassed design allows for multiple zones of damping control, providing a comfortable ride on rough terrain while maintaining exceptional support during high-speed maneuvers. This technology manages hard bottom-outs and harsh top-outs effectively, ensuring a controlled and confident ride in demanding environments.

Constructed with a 3.2-inch diameter aluminum body, the shock employs Type II anodization for enhanced corrosion resistance and durability. The finned remote reservoir increases oil capacity, houses an Internal Floating Piston (IFP), and is equipped with a Dual Speed Compression (DSC EVO) adjuster. The DSC EVO utilizes Variable Valve Control (VVC) to independently adjust high and low-speed damping circuits without preloading the shim stack, resulting in a smoother ride and increased capacity for absorbing big impacts. Fine-tune your suspension with additional high-speed compression clicks, optimizing performance for various terrains and driving styles.

This shock features application-specific springs and vehicle-specific tuning to maximize control and comfort. The 7/8-inch hard chromed steel shafts, along with redundant sealing systems including a main seal, wiper seal, and scraper seal, ensure longevity and consistent performance in harsh conditions. The impact-extruded and CNC-machined 6061-T6 aluminum bodies, combined with features like fins and a robust piston design, guarantee strength and reliability. Whether you're tackling rocky trails or high-speed desert runs, the FOX 3.2 Internal Bypass shocks provide the support, adjustment, and confidence needed for superior off-road performance and durability.
