Rancho RS9000XL 4″ Rear Lift Shocks for 1992-1999 Chevy Suburban 1500 4WD

Part Number: RS999227

Summary: The Rancho RS9000XL series provides industry-leading versatility for the 1992-1999 Chevy Suburban 1500 and GMC Yukon. Featuring a manually adjustable 9-position damping system, these shocks allow drivers to instantly tune their ride quality from soft street cruising to firm, controlled towing. Specifically configured for 4-inch rear lift heights, they deliver the necessary travel and damping control to manage the heavy chassis of classic GMT400-platform SUVs.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the perfect balance between highway comfort and off-road stability.
• Large Shock Body: A heavy-duty 2.75-inch diameter reserve tube provides increased oil capacity to ensure consistent performance and reduced fade during high-temp operation.
• Nitrogen Gas Charged: High-pressure gas integration provides immediate response to road imperfections to ensure zero aeration and consistent tire-to-ground contact.
• Polyurethane Bushings: High-durability polyurethane material provides superior resilience against environmental debris to ensure long-term service life and reduced noise.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a manual 9-position knob located at the base of the shock body, allowing you to click through settings without tools.

Will these shocks lift my Chevy Suburban?
No, these shocks do not create lift. They are specifically valved and length-matched to accommodate vehicles already equipped with a 4-inch rear lift kit.

What is the benefit of the larger shock body?
The 2.75-inch body holds more fluid than standard shocks, which helps dissipate heat faster and prevents the “fading” feeling during long trips or off-road use.
