Rancho RS999058 Shock Absorber - Rear
Rancho RS9000XL Rear Shock Absorber
The Rancho RS9000XL RS999058 is a rear suspension shock absorber built for drivers who want adjustable ride control for towing, daily driving, and off-road use. With nine manual settings, it lets you tune damping to match load, road conditions, and driving style.

RS9000XL Product Line
Rancho’s RS9000XL line is known for manual adjustability, giving you control over shock response without changing the hardware. That makes the RS999058 a practical choice when the vehicle sees mixed use, such as commuting during the week and towing or trail driving on the weekend.
Detailed Description
The Rancho RS999058 rear shock absorber is engineered for vehicles that need consistent control under changing load conditions. Its nine-position adjustment range helps tailor rear suspension response for smoother unloaded driving, firmer towing support, and more controlled handling on uneven surfaces. The LS47 loop bushing and sleeve mounts at both ends simplify application matching on the listed rear positions, while the included dust shield adds protection in exposed underbody environments. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Excessive rear bounce after bumps or dips
- Rear-end instability when towing or carrying cargo
- Harsh or inconsistent ride response on mixed road surfaces
- Reduced control on rough pavement or light off-road terrain
- Need for a rear shock absorber with adjustable damping
Installation Notes and Tips
Verify rear fitment by year, make, model, and suspension notes before ordering. This shock fits 2011-2013 Ram 2500, rear; 2006-2010 Dodge Ram 2500, rear; 2002-2006 Chevrolet Avalanche 1500, rear; 2000-2006 Chevrolet Suburban 1500, rear; 2001-2006 Chevrolet Tahoe, rear; 2001-2006 GMC Yukon, rear; 2000-2006 GMC Yukon XL 1500, rear; 2000 Chevrolet Tahoe, rear; and 2000 GMC Yukon, rear.

Confirm the vehicle does not have self-leveling suspension or electronic adjustable suspension where noted.
Quality Assurance
Rancho positions the RS9000XL series as a manually adjustable shock line for on-road and off-road use, towing, and load-sensitive driving. RS999058 follows that product-line approach with application-specific dimensions and mounting details for the listed vehicles.
