Fabtech 3.5in HD Uniball Upper Control Arm Kit | GM C/K2500HD/3500HD 11-18 2WD/4WD (FTS21126)

The Fabtech 3.5-inch HD Uniball Upper Control Arm Kit is a high-performance suspension component designed for GM C/K2500HD and 3500HD trucks from 2011 to 2018, available for both 2WD and 4WD configurations. Constructed with chromoly tubing for enhanced strength and reduced flex, these control arms feature a super strong 1-inch ID stainless American uniball that replaces the upper ball joint, providing increased durability and precise steering feedback. The design incorporates additional caster built into the arms, improving alignment capabilities and addressing problematic leveling kit alignments. The 4340 heat-treated uniball pin fits into the factory ball joint taper without modification, allowing for easy return to stock if needed. These arms enable increased wheel travel when used with Dirt Logic 2.5 coilover shocks, making them ideal for off-road and performance applications.

Designed for 2011–2018 GM C/K2500HD and 3500HD trucks, these control arms serve as a robust upgrade for lifted or leveled suspensions. They are a direct bolt-on replacement for stock upper control arms, offering improved strength, alignment, and wheel travel. Suitable for off-road enthusiasts, daily drivers, and those seeking enhanced suspension performance, the kit includes the control arms and necessary hardware for installation. Compatibility with factory components ensures straightforward installation without modifications, making these arms a reliable choice for upgrading the suspension system on heavy-duty trucks.
