Rancho 86-97 Nissan D21 Front RS5000X Shock

The 16mm nitro-carburized piston rod on this Rancho RS5000X shock is built to resist scuffs and corrosion, setting a solid foundation for improved on- and off-road handling for your 1986-1994 Nissan D21. This shock absorber is designed to give you better control and a smoother ride by incorporating Rancho's exclusive valving systems. The application-specific piston and Compression Control Valve work together to manage fluid transfer, absorbing impacts effectively without causing flutter and maintaining consistent shock motion control.

Inside, a large twin-tube body filled with all-weather fluid allows for cooler operation, even in extreme temperatures ranging from -40 to 248°F, which helps reduce damping performance fade and foaming. You'll also notice a smoother ride thanks to the polyurethane rebound bumper and rubber bushings that absorb harshness, while the fluon-banded piston responds quickly to changing road conditions. Rancho also uses a low-friction, self-lubricating seal to keep gas and oil in place for quicker rebound and smoother compression, further enhancing the overall driving experience.

This shock absorber is well-built with double-welded loops at stress areas and a 35mm sintered iron piston for enhanced structural integrity, all protected by a polyvinyl boot. It's a popular choice for those looking to improve their vehicle's handling and performance.
