Description
Bolt-on Fox 2.5 performance from the brand that sets the benchmark for off-road damping.
The Fox Performance Series 2.5 shock brings race-bred technology to daily-driven trucks. A 2.5-inch aluminum body, large-diameter race piston, and precision valving deliver consistent, fade-resistant performance whether you’re commuting, towing, or hitting washboard at speed. Tuned specifically for 2020+ Silverado HD/Sierra HD running 1.5-2.5 in above stock, these front shocks drop right in — no fabrication, no compromise.
