Fabtech uniball upper control arm kit for 2017–2018 Ford Raptor replaces the factory upper ball-joint arms with spec-built uniball arms for greater strength and alignability. The design uses 1.50in ID FK American uniballs, 17-4 heat-treated stainless steel pins and 4130 chromoly arm construction with FK American heim mounts to eliminate the stock upper ball joint and provide a more durable direct-replacement solution.
