Rancho RS5000X 4″ Rear Lift Shocks for 1988-1999 GMC K1500 4WD

Part Number: RS55227

Summary: The Rancho RS5000X series leverages CrossFlow technology to provide a versatile ride for your GMC K1500. Designed specifically for vehicles with a 4-inch rear lift, these gas-pressurized twin-tube shocks excel at absorbing harsh impacts while maintaining smooth street manners. The larger shock body allows for increased fluid capacity, ensuring consistent damping performance during daily driving or light off-road use.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between damping forces to ensure maximum comfort on varied terrain.
• CrossFlow Technology: A unique internal valve design provides consistent oil flow to ensure the shock remains cool and responsive under load.
• Nitrogen Gas Pressurization: High-pressure gas charge minimizes aeration and foaming to ensure immediate damping response and reduced fade.
• Nitro-Carburized Piston Rod: A 16mm heavy-duty rod finish provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.

Frequently Asked Questions

Will these shocks lift my GMC K1500?
No, these shocks do not create lift. They are specifically configured for vehicles that already have a 4-inch lift kit installed to ensure proper travel and prevent bottoming out.

Does this include both rear shocks?
Yes, this SKU (2xRS55227) includes a pair of shocks for the rear of your vehicle.

What is the benefit of the CrossFlow technology?
CrossFlow technology helps circulate oil more efficiently through the valving system, which prevents the shock from becoming harsh during rapid cycling over rough roads.
