RS5000X Strut
If your original Shock / Strut is surrounded by a Coil Spring, replacing just the bare cartridge may require a Coil Spring Compressor to safely remove and reuse the spring and mount (not included) from your original assembly.
Featuring a unique, exclusive valving system and advanced compression functionality, RanchoŽ RS5000X struts deliver improved overall on- and off-road handling and performance.

Features:
  • Improved Handling & Performance - Cross Tuned technology featuring exclusive rebound valving system and advanced compression phase improves overall handling and performance on and off road
  • Minimizes Rough Ride - Exclusive Progressive Engagement Valving is custom-tuned for each vehicle to help reduce initial impacts at low speeds and minimizes a rough ride
  • Strong & Durable - Features a nitro-carburized piston rod to resist scuffs & corrosion, double-welded loops at stress areas, sintered iron piston for enhanced structural integrity and polyvinyl protective boot
  • Handles Extreme Temperature Changes - Large twin-tube body filled with all-weather fluid for cooler operation, increased vehicle control and ability to withstand internal temperatures of -40 to 248°F
  • Smooth Performance - 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
  • Reduces Fade - Nitrogen gas pressurized to 60 PSI to minimize air-to-oil mixture to reduce damping performance fade and foaming
  • Maintains Vehicle Control - 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
  • Built To Last - Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression while the piston delivers heightened control of shock motion due to the expanded piston area
