Summary: The Rancho RS66351 LEVEL IT Torsion Key System provides a leveled stance and improved ground clearance for your GMC Sierra 2500HD.

• Cross-Flow Technology: The RS5000X shocks’ unique valve design provides a faster response to road imperfections to ensure consistent damping during daily driving and hauling.
• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between low and high-speed impacts to ensure maximum driver comfort.
• Protective Boot Included: High-quality polyvinyl accordion boots provide a barrier against dust, mud, and debris to ensure the longevity of the polished chrome piston rods.
