Fabtech 2021 Ford F-150 4WD 4-6in Uniball UCA Kit

If you're looking to beef up the front suspension on your 2021-2023 Ford F-150 4WD, especially for offroad adventures, Fabtech's Uniball Upper Control Arm (UCA) Kit is a solid choice. These arms replace the stock ball joint UCAs, which can wear out under heavy use. By upgrading to these, you're adding significant strength to your front end, making it more durable for rugged conditions. They're also designed to provide additional caster compared to stock, which really helps with steering stability and handling when you're running larger tires on the road.

Fabtech builds these arms using .120 wall, 1.50 inch OD 4130 Chromoly tubing, which is a strong and reliable material for suspension components. Inside, they use American-made 1 inch FK Stainless PTFE lined Uniballs. These are known for their smooth operation and durability. The Uniball pins are made from heat-treated 17-4 Stainless Steel and are designed to fit directly into your F-150's factory ball joint tapers, meaning you won't need to modify your spindles to install them, and you can easily switch back to stock if needed. For the frame side, they've included quality urethane bushings that help absorb road noise and vibrations, contributing to a more comfortable ride and longer component life.

This kit is a substantial upgrade for your F-150's suspension, whether you're starting with a stock setup or already have a lift. It's built for drivers who want dependable performance and increased capability for their truck.
