Rancho RS55152 Pair of Front RS5000X Series Suspension Shock Absorbers fits 1988-1999 K1500/K2500 Model Vehicles with 1-2.5" Front Lift and OE Style Upper Ball Joints | Built to Last

This set comes with two front Rancho RS5000X Shocks. Cross Tuned technology featuring an exclusive rebound valving system and advanced compression phase improves overall handling and performance on and off road. Exclusive Progressive Engagement Valving is custom-tuned for each vehicle to help reduce initial impacts at low speeds and minimizes a rough ride. The RS5000X Series shock features a 16mm nitro-carburized piston rod to resist scuffs & corrosion, double-welded loops at stress areas, 35mm sintered iron piston for enhanced structural integrity and polyvinyl protective boot. Large twin-tube body filled with all-weather fluid allows for cooler operation, increased vehicle control and ability to withstand internal temperatures of -40 to 248°F. 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. Nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixture to reduce damping performance fade and foaming. The compression control valve is custom-tuned for each vehicle to regulate fluid transfer to absorb impacts without disc flutter and help maintain shock motion control. 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, the RS5000X comes with Rancho's limited lifetime warranty. This pair of RS5000X Series shocks are compatible with 1992-1994 Blazer 4WD, 1988-1999 K1500, 1992-1999 K1500 Suburban, 1988-2000 K2500, 1995-1999 Tahoe 4WD, 2000 Tahoe / Yukon 4WD (Old Body Style), and 1992-1999 Yukon 4WD.
