Cross Tuned technology: Rancho's exclusive rebound valving system and advanced compression phase help improve overall handling and performance on and off road.
Strong and durable: 16mm nitro-carburized piston rod resists scuffs and corrosion, with double-welded loops at stress areas, a 35mm sintered iron piston, and a polyvinyl protective boot.
Large twin-tube body: The 2 1/4 in twin-tube body is filled with all-weather fluid rated to withstand internal temperatures of -40 to 248°F for cooler operation.
Reduces fade: Nitrogen gas pressurized to 150 PSI helps minimize air-to-oil mixing to reduce damping fade and foaming.
A polyurethane rebound bumper, rubber bushings, and fluon-banded piston help absorb harshness for a smoother ride, and it's backed by Rancho's Limited Lifetime Warranty.
