- Cross Tuned technology: exclusive rebound valving plus an advanced compression phase, with Progressive Engagement Valving custom-tuned per vehicle to help reduce initial low-speed impacts and minimize a rough ride.
- Strong and durable: 16mm nitro-carburized piston rod to resist scuffs and corrosion, double-welded loops at stress areas, a 35mm sintered iron piston, and a polyvinyl protective boot.
- Handles temperature swings: large 2-1/4 in twin-tube body filled with all-weather fluid for cooler operation, rated to withstand internal temperatures of -40 to 248°F.
- Reduces fade: nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing, damping fade, and foaming.
A polyurethane rebound bumper and rubber bushings help absorb ride harshness, while a low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression. Backed by Rancho's Limited Lifetime Warranty.
