The Fabtech 0-6 inch Uniball Upper Control Arm Kit is a high-performance suspension upgrade designed for GM trucks from 2014 to 2018. Featuring a robust 1-inch diameter stainless American Uniball, these arms eliminate the factory upper ball joint, providing increased durability and strength. The design incorporates additional caster built into the arms, enhancing alignment capabilities and helping to resolve problematic leveling kit alignments. When paired with Dirt Logic 2.5 coilover shocks, these control arms allow for increased wheel travel, improving off-road performance and ride quality. Constructed from chromoly tubing, the arms reduce flex compared to stock components, resulting in a more positive road feel and improved handling. The stainless steel Uniball pin fits into the factory ball joint taper without modification, enabling easy return to stock if needed.

Designed specifically for 2014-2018 GM trucks, these control arms are a direct bolt-on upgrade that enhances suspension performance and durability. They are suitable for off-road enthusiasts, daily drivers, and those seeking improved wheel travel and alignment precision. The kit includes the upper control arms with stainless Uniballs and necessary hardware for installation. Compatibility with factory spindles and ball joint tapers ensures straightforward installation without additional modifications. These arms are ideal for applications requiring increased suspension articulation, better alignment, and enhanced handling on and off-road.

The kit is ideal for drivers looking to optimize their suspension geometry while maintaining factory-like ride quality and reliability.
