The Factory Race Series 2.5 Internal Bypass shock delivers patented race-dominating position sensitive damping technology and performance in a hassle free bolt-on kit. Patented, position sensitive internal bypass technology contains internal passages that allow fluid to bypass the piston through regulated ports as it moves through the travel. They allow for a plush predictable ride over normal off-road driving conditions and also have the ability to ramp up damping force for extreme use.

These heavy-duty, steel-bodied shocks are loaded with anodized billet aluminum components and race-bred internal valving. They are designed to bolt right on with your aftermarket long-arm suspension lift kit. Large 2.5 inch remote reservoirs with a large -10 hose increasing the shocks cooling capabilities. The Factory Race 2.5 Series Internal Bypass shocks utilizes all of the same components from our race winning Trophy Truck shocks with stainless steel shock shafts, PTFE-lined spherical bearings, proprietary racing oil and high-temp Viton® seals.
