Rancho RS5000X 2.5-4″ Lift Shocks for 1969-1980 Chevy Blazer 4WD

Part Number: RS55001

Summary: The Rancho RS5000X series leverages a patented progressive engagement valving system to deliver a smooth, controlled ride for lifted Chevy and GMC SUVs. Designed specifically for vehicles with 2.5 to 4 inches of lift, these gas-pressurized twin-tube shocks provide exceptional durability and dent resistance during off-road use. By minimizing aeration and foaming, these shocks ensure consistent damping performance whether you are navigating highway expansion joints or rugged trails.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a soft initial response for comfort to ensure stability during aggressive maneuvers.
• Gas Pressurization: Nitrogen gas charging provides a reduction in fluid aeration and foaming to ensure consistent damping force in high-duty cycles.
• Twin-Tube Body: A 2.25-inch diameter outer tube provides protective shielding for the internal piston rod to ensure long-term durability against rock chips and trail debris.
• Polyurethane Bushings: High-density mounting material provides enhanced road vibration isolation to ensure a quiet and comfortable cabin environment.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift; they are specifically configured for vehicles already equipped with a 2.5 to 4-inch suspension lift to ensure the piston operates within its optimal travel range.

Does this include all four shocks?
Yes, this specific SKU (2xRS55001_2xRS55112) is a complete set including two front and two rear shocks for a total of four units.

Are the boots required for installation?
While the shocks will function without them, the included red boots are highly recommended as they provide a barrier against mud and debris that can damage the internal seals.
