Rancho Suspension Shock Absorber P/N:RS55144
$90.99
Smooth out rough roads and keep your Toyota planted with the Rancho RS5000X Suspension Shock Absorber (RS55144). This rear (right-side) shock installs as a direct-fit replacement for the 1984-1985 Toyota 4Runner, 1988-1989 Toyota Land Cruiser, 1984-1992 Toyota Pickup, and 1995-1998 Toyota Tacoma. Built around Rancho's exclusive Cross Tuned technology — a rebound valving system paired with an advanced compression phase — it's designed to improve on- and off-road handling and performance.
- Progressive Engagement Valving: custom-tuned for each 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 twin-tube body (2 1/4 in) filled with all-weather fluid for cooler operation and rated to withstand internal temperatures of -40 to 248°F.
- Reduces fade: nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing that causes damping fade and foaming.
A polyurethane rebound bumper, rubber bushings, and fluon-banded piston help absorb harshness for a smoother ride, and a low-friction, self-lubricating seal retains gas and oil for quicker rebound. Backed by Rancho's Limited Lifetime Warranty.
