A-Arm 11in Screw In B/J Slotted Bearing

The A-Arm 11in Screw In B/J Slotted Bearing upper control arm from JOES RACING PRODUCTS is engineered for racers and high-performance enthusiasts who demand precision front-end geometry adjustments. This tubular aluminum and steel control arm with a 10-degree bend is designed for circle track racing, road course, and drag racing applications where adjustability and reliability directly impact lap times and chassis balance. Built to withstand the lateral and vertical loads of competitive motorsports, this component replaces OEM control arms with a stronger, lighter alternative that accepts screw-in ball joints for tool-free serviceability.

The 11-inch length and 10-degree geometry are critical for controlling caster and camber angles in custom suspension setups where factory mounting points are retained or modified. The slotted bearing design accommodates ball joint movement with minimal bind, while the screw-in ball joint interface allows quick replacement without pressing or special tools—essential during pit stop adjustments or mid-season component swaps. Powder-coated in black for corrosion resistance and durability, the tubular construction minimizes unsprung mass without sacrificing torsional rigidity. The 3.9-pound weight keeps rotating mass low while maintaining the strength required for repeated shock loads at speed.

Competitors in dirt late models, asphalt modifieds, and bracket racers benefit most from this control arm when building or refreshing a custom front suspension system. Installation pairs with adjustable ball joints, tie-rod ends, and suspension bushings tuned to your specific track geometry and driving preference. Verify mounting bore alignment with your frame or spindle assembly before purchase, as this arm is sold individually and requires a matching lower control arm and related hardware to complete your suspension.
