A-Arm 10.5in 20deg Screw In B/J Slotted Bearing

The A-Arm 10.5in 20deg Screw In B/J Slotted Bearing from JOES RACING PRODUCTS is engineered for serious suspension builders and racers who demand precision geometry in their front-end setups. This component is essential for custom A-arm applications where proper ball joint alignment and load distribution directly impact handling, tire wear, and safety on road courses and drag strips. Whether you're building a tube chassis race car, upgrading a vintage hot rod, or fine-tuning an off-road competition vehicle, this screw-in bearing assembly delivers the adjustability and durability required for high-performance suspension systems.

The 10.5-inch length and 20-degree geometry are optimized for specific suspension angles commonly used in competition setups, allowing you to dial in caster, camber, and kingpin inclination precisely. The screw-in design enables fine adjustment without requiring complete arm replacement, making geometry changes quick and cost-effective during setup refinement. The slotted bearing surface reduces friction and wear while the ball joint interface handles the lateral and vertical loads imposed during acceleration, braking, and cornering. JOES RACING PRODUCTS manufactures these arms to exacting tolerances, ensuring repeatability across multiple vehicles and maintaining dimensional stability under sustained g-loads and shock inputs.

Professional race teams, suspension shops, and dedicated enthusiasts building custom front ends will appreciate the modular nature of this screw-in bearing system. Installation involves secure mounting to your tubular frame using proven JOES mounting standards, with the slotted bearing design accommodating both horizontal and slight angled loads. This arm pairs seamlessly with JOES steering components, uprights, and brake systems for a fully integrated, geometrically optimized front suspension. Weighing 3.84 lbs and dimensioned at 13.6 x 3 x 13.7 inches, it integrates efficiently into tight chassis layouts while maintaining structural rigidity critical for high-speed stability.
