BUILT TO LAST -- Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression while the application-specific piston delivers heightened control of shock motion due to the expanded piston area
BUY WITH CONFIDENCE -- Comes with Rancho’s Limited Lifetime Warranty

IMPROVED HANDLING AND PERFORMANCE -- Cross Tuned technology featuring exclusive rebound valving system and advanced compression phase improves overall handling and performance on and off road

MINIMIZES ROUGH RIDE -- Exclusive Progressive Engagement Valving is custom-tuned for each vehicle to help reduce initial impacts at low speeds and minimizes a rough ride
REDUCES FADE -- Nitrogen gas pressurized to 60 PSI to minimize air-to-oil mixture to reduce damping performance fade and foaming
SMOOTH PERFORMANCE -- Polyurethane rebound bumper and rubber bushings help absorb ride harshness while the fluon-banded piston enhances responsiveness to changing road conditions for an overall smoother ride
