Rancho RS9000XL 1-2.5″ Rear Lift Shocks for 1988-2000 GMC K2500 4WD

Part Number: RS999190

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC K2500, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable shock allows owners to instantly tune damping levels to compensate for varying payloads, towing demands, or off-road conditions. Engineered for vehicles with 1-2.5 inches of rear lift, these shocks provide a custom-tailored ride quality that transitions from street comfort to firm control with a simple turn of a dial.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the perfect ride for towing, hauling, or daily commuting.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road irregularities to ensure consistent tire-to-road contact.
• Polyurethane Bushings: Durable polyurethane material provides enhanced responsiveness and longevity to ensure quiet operation under extreme stress.

• Performance Benefit: Drivers gain the ability to firm up the suspension for stable towing and soften it for unladen highway driving, eliminating the compromise found in non-adjustable shocks.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The shocks feature a 9-position knob located at the base of the shock body. You can manually click the dial to a higher setting for more firmness or a lower setting for a softer ride.

Do these shocks create the 2.5-inch lift?
No, these shocks do not create lift. They are specifically valved and length-matched to be used on vehicles already equipped with 1 to 2.5 inches of rear lift height.

What is the benefit of the large 2.75-inch body?
The larger body allows for more oil capacity, which helps dissipate heat faster. This prevents “shock fade” during long periods of towing or off-road driving.
