Fox CHEVROLET SILVERADO & GMC SIERRA 2500/3500 | 2.5 PS 4-6" Rear shock

The FOX 2.5 Performance Series HTO delivers precision engineering tailored for Chevrolet Silverado and GMC Sierra 2500/3500 applications. This bolt-on shock integrates position-sensitive damping technology with vehicle-specific valve tuning and oversized pistons to enhance both highway and trail performance. The 2.5-inch body features a Type II anodized aluminum construction that excels at thermal management while resisting oxidation. An internal floating piston design isolates shock fluid from pressurized nitrogen, ensuring consistent damping response across varying terrain and load conditions.

Hydraulic Top Out (HTO) technology offers usable position-sensitive rebound damping control on and off the pavement. HTO reduces harsh top-outs and increases comfort by forcing shock oil through a secondary shim stack to slow down shock shaft speed; HTO is particularly beneficial after installing heavier, aggressive tires and applications lifted higher than OEM specification.
