Description
Upgrade your truck’s front suspension with the Fabtech K1181M Uniball Lift System with Shocks. Designed for increased wheel travel and mild lift performance, this heavy-duty system combines tubular upper control arms with Fabtech Dirt Logic coilover and rear shock technology. It is engineered to enhance off-road suspension performance while maintaining a durable, well-tuned ride for demanding trail and street use.
The upper control arms are constructed from 1.25-inch outside-diameter chromoly tubing with a .120-inch wall thickness for strength and rigidity. Stainless steel 1-inch uniballs replace the factory upper ball joints and attach to the factory spindle without drilling. This design provides improved suspension articulation and helps eliminate the limitations of the original upper control arm configuration.
The Fabtech K1181M system is designed to work with Dirt Logic 2.5 coilover shocks at the front and Dirt Logic 2.25 shocks at the rear, creating a complete suspension upgrade with carefully tuned damping characteristics. The system is listed with a 0-inch lift/drop height and is engineered for select heavy-duty GM trucks, including the 2020-2021 Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD. Professional installation is recommended, and applicable California Proposition 65 warnings apply.
