Ball Joint Pin K727 +.400in

The ALLSTAR PERFORMANCE Ball Joint Pin K727 +.400in is a precision suspension component designed for builders and mechanics who require repeatability in front-end geometry. This oversized pin is particularly useful for addressing wear and clearance issues in factory or custom ball joint applications, ensuring proper articulation and eliminating play that can compromise handling and tire wear.

Engineered to tight tolerances, this pin maintains consistent bore engagement and stable suspension kinematics under load. The +.400-inch oversize dimension is critical for compensating for worn ball joint sockets or allowing the use of rebushed housings without sacrificing fit or preload characteristics. Installation requires precision boring or honing of the ball joint housing to match the pin diameter, making it suitable for shops with dedicated suspension expertise.

This pin is ideal for race-prepared vehicles, high-performance street builds, and restoration projects where original equipment no longer meets functional or dimensional standards. It is specifically designed for independent front suspension and control arms, making it a valuable tool for technicians rebuilding upper or lower ball joints in various vehicle types, including hot rods and classic cars.
