Product Description

The Fabtech FTS21128 Uniball Upper Control Arms are engineered to enhance the front suspension of 2007-2018 Chevrolet Silverado and GMC Sierra 1500 models. Designed for vehicles with a 0-6" lift, these control arms replace the factory ball joints with robust 1" ID stainless steel uniballs, providing increased strength and durability for off-road applications.

Constructed from high-quality .120" wall 4130 chromoly tubing, these control arms offer superior strength and resistance to flex. The inclusion of 17-4 stainless steel misalignment spacers and heat-treated 4340 tapered uniball pins ensures a secure and reliable fitment. Additionally, the arms feature built-in caster adjustments to improve alignment, particularly beneficial for vehicles equipped with leveling kits.

Installation is straightforward, as these control arms are direct replacements for factory forged black steel upper control arms. They are compatible with Dirt Logic 2.5 coilover shocks, allowing for increased wheel travel and improved handling performance. Whether you're tackling rough terrains or seeking enhanced off-road capabilities, the Fabtech FTS21128 Uniball Upper Control Arms are a reliable upgrade for your vehicle.
