Product Description

The FOX 985-26-191 is a 2.0 Performance Series front smooth body reservoir shock with low-speed compression adjustment for 2011-2019 Chevy Silverado and GMC Sierra 2500 HD and 3500 HD trucks. It is designed for drivers who want stronger front-end damping control, improved heat management, and added tuning flexibility over a standard non-adjustable shock. The external reservoir increases fluid and gas capacity, while the LSC adjuster allows the shock to be tuned for changing terrain, ride preferences, and vehicle load.

Verified trusted-source data supports front fitment for 2011-2019 GM 2500HD and 3500HD applications with 1.5 to 3.5 inches of front lift. The lift amount applies to the front only; rear lift is not provided by this part number. Cross-validated specs include 7.12 inches of travel, 20.28-inch extended length, 13.18-inch collapsed length, bar-pin upper mount, clevis lower mount, and an included aluminum reservoir clamp.

This shock is best suited for leveled or mildly lifted heavy-duty Silverado and Sierra builds used for towing, hauling, rough-road driving, and off-road travel. This part is sold individually, so 2x shocks are typically required for a complete front axle installation.
