Chevrolet Silverado 2500 HD Shock Absorber - Rear - FOX Performance Series 2.5 (2020–2023). A purpose-built rear shock that pairs off-road control with confident on-road manners for your Silverado 2500 HD.

Featuring a 2.5 in impact-extruded 6061-T6 aluminum body and a race-developed main piston, this IFP design separates gas and oil for consistent, fade-resistant damping. Application-specific valving for 2020–2023 GM 2500/3500 reduces sway and keeps response predictable across rough terrain and highway miles alike. Compatible with 6.5 in lift rear setups, the Type II clear-anodized finish helps resist corrosion, while the fully serviceable, re-tunable architecture supports long-term ownership.
