Fabtech Uniball Upper Control Arms (MPN: FTS21126)

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

Fabtech Uniball Upper Control Arms are engineered for severe duty applications, compatible with 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 4130 chromoly tubing, these arms feature a tubular design with a positive 2.5 degree caster built in, ensuring improved handling and stability.

The heavy-duty construction includes a welded gusset that reinforces the uniball cup to the chromoly arm tubes, providing exceptional strength. The arms are designed with a large 1 inch inner diameter stainless steel PTFE lined FK uniball bearing, which is indexed to the arm for increased travel when used with Dirt Logic coilover shocks. Additionally, the heat treated 4340 uniball pin allows for straightforward installation without modifications to the spindle, ensuring that the arms can be removed and returned to stock configuration without complications.

Included with the control arms are misalignments made of 17-4 stainless steel, which facilitate uniball travel without interference, while enhancing the strength of the pin's cross section. This set of two control arms is painted black for durability and corrosion resistance, making them a reliable choice for off-road enthusiasts seeking to enhance their vehicle's performance.
