Dial in the back end of your 2014+ Ram 2500 / 2013+ Ram 3500 with the FOX 2.5 Performance Series IFP HTO Rear Shock, valved for 2–3 in. of rear lift. You get extended drop-out travel for more off-road capability and performance-minded valving for a connected on-road ride with less sway.
Why Choose the FOX 2.5 Performance Series IFP HTO Rear Shock?
- Tuned for 2–3 in. of rear lift – valving built specifically for this Ram application at this lift height
- Hydraulic Top Out (HTO) – position-sensitive rebound control forces oil through a secondary shim stack to slow shaft speed and stop harsh top-outs, a big help on lifted trucks running heavier, aggressive tires
- More drop-out travel – extends usable travel in most applications so the rear axle stays planted off-road
- True internal floating piston – the IFP separates oil from high-pressure nitrogen to prevent aeration and keep damping consistent
- Fade-resistant aluminum body – aluminum sheds heat four times better than conventional materials, so performance holds up on long, rough runs
- Fully serviceable – torture-tested, race-proven, and resistant to corrosion and harsh environments
