- Cross Tuned technology: Rancho's exclusive rebound valving system and advanced compression phase help improve overall handling and performance on and off road.
- Progressive Engagement Valving: Custom-tuned for each vehicle to reduce initial impacts at low speeds and minimize a rough ride.
- Strong and durable: 16mm nitro-carburized piston rod resists scuffs and corrosion, with double-welded loops, a 35mm sintered iron piston, and a polyvinyl protective boot.
- All-weather twin-tube design: Large twin-tube body filled with all-weather fluid runs cooler and withstands internal temperatures of -40 to 248°F; nitrogen gas pressurized to 150 PSI helps minimize air-to-oil mixing to reduce fade and foaming.
A polyurethane rebound bumper, rubber bushings, and fluon-banded piston smooth ride harshness, and a low-friction self-lubricating seal supports quicker rebound. Backed by Rancho's Limited Lifetime Warranty.

What are signs my shock absorber may need replacing?
Common signs include excessive bouncing after bumps, a rougher ride, nose-diving under braking, or visible fluid leakage. Have the suspension inspected to confirm the shock is the cause.
Should I replace shocks in pairs?
