A-Arm 9.5in Screw In B/J Slotted Bearing

The A-Arm 9.5in Screw In B/J Slotted Bearing from JOES Racing Products is engineered for serious suspension builders and fabricators who demand precision adjustability in their vehicle's front-end geometry. This component addresses a critical need in street rod, off-road, and race car builds where fine-tuning camber, caster, and toe-in settings is essential for handling balance and tire wear optimization. The 9.5-inch length positions this bearing as an ideal upgrade for mid-sized A-arm assemblies found in classic hot rods, modern race cars, and heavily modified street vehicles.

The screw-in design with slotted bearing allows for micro-adjustments without full disassembly, a feature that separates professional-grade suspension geometry from basic bolt-on solutions. The ball joint (B/J) interface provides robust articulation under load while the slotted bearing configuration enables precise alignment dial-in during initial setup or mid-season tuning. JOES Racing Products' manufacturing standards ensure concentricity and bearing preload consistency, critical factors that prevent binding, excessive play, or premature wear under the dynamic loads encountered during acceleration, braking, and cornering.

This bearing excels in applications where suspension geometry optimization directly impacts lap times and tire longevity—primarily circle-track racing, road course competition, and high-performance street builds. Installation requires basic mechanical knowledge and access to a torque wrench and alignment equipment; many builders pair this component with a four-wheel alignment check to verify camber and caster targets. Compatibility depends on your specific A-arm length and ball joint configuration, so verify mounting points and thread specifications with your chassis manufacturer or suspension designer before purchase.
