Why Aftermarket A-Arms Create Ball Joint Clearance Problems

Aftermarket suspension arms are often designed with additional material around the ball joint pocket for added strength — which is great for durability, but creates a clearance problem when installing standard top caps. The extra material prevents the cap from seating flush, leaving the ball joint improperly secured or requiring modification to the arm itself. The Black Ops Machine Tight Clearance Top Cap solves this with a profile specifically designed to clear that excess material while still providing a solid, rattle-free seat for your HD ball joint. It's the right part for the job — no grinding, no improvising, no compromises.
