Transform your suspension with FOX's Factory Race Series 2.5 Coilover Reservoir Shocks – front and rear – engineered for lifted 2007–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 (2WD & 4WD). The front coilovers (883-02-121) deliver up to 2 inches of front lift with a shock travel of 4.36 inches, giving you the clearance and comfort you need on- and off-road. These bolt-on coilovers feature FOX’s patented internal bypass zones for a plush ride on pavement and controlled damping in rough terrain. They're built with 2.5" smooth bore zinc-plated steel bodies, hard-anodized aluminum components, and 7/8" chrome-plated steel shafts to endure heavy off-road abuse.
In the rear, FOX’s 2.5 Factory Race Series Shocks (883-24-003) offer up to 0–1.5 inches of lift with a massive shock travel of 8.97 inches, making them ideal for high-articulation rear suspension setups. The remote reservoirs provide increased oil capacity and consistent performance during extended use or aggressive driving. With a race-developed piston, redundant sealing systems, and application-specific valving, these rear shocks deliver the control, comfort, and reliability needed for overlanding, towing, or off-road adventuring. Fully serviceable and tunable, this front and rear coilover and shocks set is a no-compromise upgrade for serious performance.
