Rancho RS90000XL 5-6″ Rear Lift Shocks for 1999-2004 GMC Sierra 2500 4WD

Part Number: RS999056

Summary: The Rancho RS9000XL series delivers unmatched versatility for heavy-duty applications through its industry-leading adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting for heavy towing or aggressive off-road use. Specifically configured for vehicles with 5-6 inches of rear lift, they provide the necessary travel and control to manage increased ride heights without sacrificing comfort.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride quality for any load or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure consistent performance and reduced fade during extreme use.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road irregularities to ensure maximum tire-to-ground contact.
• Protective Boot: A heavy-duty liquid metallic finish and included dust boot provide a secondary layer of protection against debris to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features an external 9-position knob at the base of the shock that can be turned by hand to increase or decrease damping resistance.

Will these shocks lift my truck?
No, these shocks do not create lift; they are specifically lengthened and valved to accommodate vehicles already equipped with a 5-6 inch lift kit.

Can I use these on a stock-height GMC Sierra 2500?
No, these shocks are significantly longer than factory units. Installing them on a stock-height vehicle will cause the shock to bottom out and fail.
