A-Arm 10in Screw In B/J Slotted Bearing

The A-Arm 10in Screw In B/J Slotted Bearing control arm from JOES RACING PRODUCTS is purpose-built for high-performance suspension tuning and competitive motorsports applications. This tubular upper control arm delivers the adjustability and precision that serious racers demand when dialing in front-end geometry for maximum grip and consistent handling. Whether you're preparing a street-strip machine, circle track competitor, or road-course platform, this component addresses the critical need for accurate caster, camber, and ride height control.

Engineered from aluminum and steel construction with black powder-coat finish, the A-Arm 10in control arm features a 10-degree geometry offset and screw-in ball joint design for easy replacement and field adjustment without press equipment. The slotted bearing style allows riders to fine-tune suspension geometry mid-season without full arm replacement, saving both time and cost during setup iterations. The tubular design minimizes unsprung weight while maintaining rigidity, and the precision machining ensures accurate pivot points that maintain suspension compliance and predictable brake dive characteristics under hard deceleration.

This component benefits independent front suspension systems where bump-steer correction and geometry optimization are critical to lap-time improvement and driver confidence. The 10-inch length and 10-degree included angle suit mid-sized chassis and modern independent suspension architectures common in club racing, drag racing, and vintage motorsports builds. Installation requires basic hand tools and suspension knowledge; the screw-in ball joint interface simplifies maintenance and allows technicians to swap worn joints without specialized shop equipment, making it ideal for owner-operators and professional race shops alike.
