2011-2025 25/3500 HD 0-2.5" Fox 2.5 HTO Performance Series Front Shock (KRS4010)

FOX's new 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.

• High-flow velocity-sensitive damping
• 5/8” hard chrome shaft
• Hydraulic Top Out (HTO) piston
• Internal floating piston (IFP)
