Rancho RS5000X Front Strut for 2007-2014 Chevrolet Avalanche, Silverado, Tahoe & GMC Sierra, Yukon (RS55786)

Fits select 2007-2014 Chevrolet Avalanche, Silverado 1500, Suburban 1500, Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL 1500.

The Rancho RS5000X series front strut (RS55786) utilizes a patented progressive engagement valving system to deliver a smooth ride on-road while maintaining the damping control required for off-road environments. Built with a twin-tube body, this strut features a larger fluid capacity to dissipate heat more effectively, ensuring consistent performance during extreme temperature shifts ranging from -40°F up to 248°F.

• Precision Valving: Progressive Engagement Valving (PEV) is custom-tuned to reduce initial impact at low speeds and minimize disc flutter for improved handling.
• Resilient Construction: Features a nitro-carburized piston rod for superior corrosion resistance and double-welded loops at stress areas for added structural integrity.
• Anti-Foam Design: Nitrogen gas pressurized to 60 PSI minimizes the air-to-oil mixture to prevent foaming and damping performance fade during heavy use.
• Enhanced Protection: Includes a polyvinyl protective boot to shield the rod and a polyurethane rebound bumper to absorb ride harshness.
• Specifications: Application-specific sintered iron piston, low-friction self-lubricating seal, and fluon-banded piston for increased responsiveness.
• Manufacturer Part Number: RS55786
