The Probearing Pro 4 Series Ball Joints are built to outperform uniballs in aftermarket upper control arms. Featuring a high-strength 4140 steel ball stud and forged 4140 housing, they provide higher side impact strength and durability. In addition to their increased strength, they enhance on-road steering feel, providing better straight-line stability and smoother return to center. With 38 degrees of articulation, they allow maximum suspension travel without sacrificing pull-out strength.
Manufacturers looking to transition to Probearing ball joints will appreciate the universal housing design, which matches the outer dimensions of most 1” uniball cups. The pivot is centered within the housing like a uniball, allowing for a seamless swap without altering the geometry.
