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

Part Number: RS999152 / RS999190

Summary: The Rancho RS9000XL series provides industry-leading adjustability for the GMC K2500, allowing drivers to switch between nine levels of performance via an integrated manual knob. This system solves the compromise between daily street comfort and heavy-duty towing stability by allowing for instant damping recalibration. Configured for vehicles with 1-2.5 inches of lift, these shocks feature a massive 2.75-inch body to maximize oil capacity and maintain consistent control under heavy loads.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the perfect ride for street, towing, or off-road applications.
• Large 2.75-in. Body: An oversized shock housing provides increased fluid capacity to ensure cooler operation and reduced fade during heavy-duty use.
• Nitrogen Gas Pressurized: High-pressure gas charges provide immediate response to road irregularities to ensure consistent tire-to-ground contact.
• Liquid Metallic Finish: A premium zinc-plated coating provides superior corrosion resistance to ensure long-term durability in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
Each shock features a 9-position knob at the base; simply turn the dial to your preferred setting—1 for softest and 9 for firmest.
