The Fox 883-26-105 Factory Race Series 3.0 Internal Bypass shock is specifically tailored for the GMC Sierra 1500 and presents cutting-edge, race-dominating damping technology. These shocks feature patented position-sensitive internal bypass technology, using regulated ports allowing fluid to bypass the piston during initial travel. The technology forces fluid through as the piston reaches extreme compression and rebound, ensuring a plush and predictable ride over typical off-road conditions. The shock can increase the damping force to counteract harsh bottom-outs or top-outs, preventing trail disruptions.

These shocks are constructed with massive 3.0-inch hard-anodized aluminum bodies, including race-bred internal valving. Designed for easy installation, they seamlessly bolt onto your aftermarket suspension lift kit using OEM shock mounts. They feature a remote recirculating reservoir bridge with a hard-anodized, CNC-machined aluminum remote reservoir equipped with external fins, acting as a heat sink for enhanced heat dissipation. Drawing inspiration from our race-winning Trophy Truck shocks, the Factory Race Series 3.0 Internal Bypass shocks incorporate top-notch components, including stainless steel shock shafts, PTFE-lined spherical bearings, proprietary racing oil, and high-temp Viton® seals.

DSC Adjusters

A Dual Speed Compression (DSC) adjuster allows you to dial in high-speed and low-speed compression settings. With the DSC adjusters, you can swiftly tailor your shocks to suit different loads, environmental conditions, and your preferred driving style. Adjust is made simply by turning the high or low-speed dials to your desired settings (10 low-speed settings, 12 high-speed settings). Meanwhile, the high-flow piston ensures stability across various terrains. FOX shocks are meticulously engineered to accommodate various activities, allowing you to unlock your vehicle's full potential on your next adventure.
