Fabtech Uniball Upper Control Arms (MPN: FTS21128)

Heavy-duty control arms for enhanced off-road performance and reliability.

Fabtech Uniball Upper Control Arms are engineered for severe duty applications, compatible with both stock and aftermarket suspension systems. These control arms replace the factory upper control arms, which are often susceptible to flex and ball joint failure, with a robust design tailored for aggressive off-road driving. Constructed from 0.120 inch wall 4130 chromoly tubing, these arms provide exceptional strength, making them suitable for high-performance environments.

The design features a welded gusset that reinforces the uniball cup to the chromoly arm tubes, ensuring durability under extreme conditions. A large 1 inch inner diameter stainless steel PTFE lined FK uniball bearing is indexed to the arm, allowing for increased travel when paired with Dirt Logic coilover shocks. Additionally, the heat-treated 4340 uniball pin facilitates installation without modifications to the spindle, allowing for easy reversion to stock configurations if necessary.

Included misalignments made of 17-4 stainless steel enhance the uniballs' travel capabilities while maintaining strength in the cross-section of the pin. This product is designed to provide a reliable upgrade for vehicles seeking improved suspension performance without the need for extensive modifications.
