Features

  • BUILT TO LAST -- 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 -- Comes with Rancho’s Limited Lifetime Warranty
  • HANDLES EXTREME TEMPERATURE CHANGES -- 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
  • IMPROVED HANDLING AND PERFORMANCE -- Cross Tuned technology featuring exclusive rebound valving system and advanced compression phase improves overall handling and performance on and off road
  • 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
  • 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
  • REDUCES FADE -- Nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixture to reduce damping performance fade and foaming
  • 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
  • STRONG AND DURABLE -- 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
