FOX Factory Race Series 3.0 Internal Bypass shocks deliver true race-bred performance in a direct bolt-on system engineered specifically for the 2019–2025 Silverado 1500 and Sierra 1500 platform. Designed for aggressive off-road driving and high-speed stability, these shocks combine patented Internal Bypass technology with advanced heat management and precision tuning.
Position-sensitive Internal Bypass technology creates multiple zones of damping control. During normal ride height operation, shock fluid bypasses the main piston through precision bleed ports for controlled comfort and stability. As the shock cycles deeper into compression or rebound, those ports close off, forcing fluid through the main piston to progressively increase damping force. This produces excellent bottom-out control, prevents harsh top-outs, and improves landing stability when driving aggressively in rugged terrain.
A finned remote reservoir with a Recirculating Reservoir Bridge continuously exchanges shock fluid between the reservoir and main body using checked ports. This system dissipates heat quickly, keeping damping consistent during sustained high-speed use.
Constructed from impact-extruded and CNC-machined 6061-T6 aluminum with Type III hard anodizing, the 3.0-inch body resists corrosion while reducing weight compared to steel designs. The Dual Speed Compression (DSC) adjuster allows independent tuning of high- and low-speed compression to dial in performance for load, terrain, and driving style.
