Lower Ball Joint Prec Screw In +.500

The Lower Ball Joint Prec Screw In +.500 by Howe is an essential suspension component designed for serious drag racers, street rod builders, and high-performance car enthusiasts. It provides the precision geometry and repeatable handling characteristics necessary for optimal vehicle performance, especially in custom and fabricated front-end suspension systems.

This screw-in ball joint features a +.500 sizing designation, indicating it is oversized by half an inch from OEM standards. This design accommodates fabricated control arms and non-traditional suspension layouts, allowing for precise caster and camber adjustments. The screw-in mechanism eliminates common press-fit tolerances, enabling technicians to achieve exact geometry specifications critical for cornering consistency and tire wear management.

Mechanics and enthusiasts benefit from this design in various applications, including bracket racing and road course competition, where suspension tuning is an iterative process. The +.500 offset extends the effective stud length, ensuring proper king-pin inclination (KPI) and scrub radius compensation in modified front ends. This product is particularly valuable for those who require repeatability between setups in their custom builds.
