Summary: The Rancho RS9000XL series is the industry leader in adjustable damping, featuring a globally recognized 9-position manual tuning knob. This Tier 2 adjustable system allows drivers to instantly transition from a soft street ride to a firm setting for heavy towing or aggressive off-road use. Engineered for vehicles with 5-6 inches of rear lift, these shocks provide the versatility required to maintain vehicle control under varying load capacities and terrain types.

Features

• 9-Position Manual Tuning: A globally patented adjustment knob provides nine levels of damping control to ensure the perfect ride for any towing or hauling scenario.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitro-Carburized Piston Rod: The 18mm heavy-duty rod provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.
• Polyurethane Bushings: High-performance polyurethane material provides enhanced durability and responsiveness to ensure a quiet and controlled suspension cycle.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock. Simply turn the dial to your desired setting: 1 for the softest ride and 9 for the firmest.

Do these shocks provide the lift for my truck?
No, these shocks do not create lift. They are specifically valved and sized to function with vehicles that have already been equipped with a 5-6 inch rear lift kit.

What is the benefit of the larger 2.75-inch body?
The increased oil capacity allows the shock to dissipate heat more effectively than standard shocks, which prevents “shock fade” during continuous use on rough roads or while towing.
