Product Description

The Rancho RS994112 is the 4th-generation RS9000XL shock absorber, replacing the discontinued RS999112 with updated construction and a refined finish. Designed for trucks, SUVs, and light-duty 4WD platforms across Chevrolet, GMC, Ford, Dodge, and Mazda, this shock delivers a wide fitment range covering vehicles from 1967 through 2010. Its defining feature is the 9-position manual adjustment knob, letting drivers dial in ride feel from soft everyday comfort (positions 1-3) to firm heavy-load control (positions 7-9) - all without tools.

Built on a 2.37-in. tri-tube body with nitrogen gas pressurization at 120 PSI, the RS994112 resists heat buildup and fade under sustained off-road or towing stress. The 18mm nitro-carburized chromed piston rod, double-welded mounting loops, and self-lubricating seal are engineered for long-term durability. Whether you're running a stock lifted Blazer, a working Dodge Ram, or a Mazda B-series with larger tires, this shock installs directly using factory mounting hardware and is backed by Rancho's Limited Lifetime Warranty.
