Fabtech 15-18 Ford F150 4WD 4130 Chromoly Steel UCA 0-6in Lift System - Component Box

Fabtech is known for building tough suspension components for off-road vehicles. For your 2021-2024 Ford F-150 4WD, these Uniball Upper Control Arms are a significant upgrade over stock. They replace the factory ball joint arms, which can wear out under aggressive off-road use, and are built for serious longevity in rugged conditions.

These heavy-duty arms are constructed from .120-inch wall, 1.50-inch OD 4130 Chromoly tubing, a strong and durable material. They feature American-made 1-inch FK Stainless PTFE-lined Uniballs, which offer greater range of motion and strength than stock ball joints. The included 17-4 stainless steel heat-treated Uniball pins fit directly into the factory ball joint tapers, meaning no modifications to your spindle are needed, making it easy to return to stock if desired. The arms also provide additional caster compared to stock, which helps with steering stability when running larger tires on the road. For the frame side, quality urethane bushings are used to absorb road noise and ensure long service life.

These Uniball Upper Control Arms are a solid option for both stock and lifted F-150s, especially if you demand the best performance and durability from your suspension system.
