A-Arm 11.5in Screw-In B/J 10 Deg.

The A-Arm 11.5in Screw-In Ball Joint with 10 degree geometry is a precision suspension component engineered for high-performance vehicles and race-oriented builds. Designed for builders and mechanics who demand adjustability and reliability in their suspension geometry, this screw-in ball joint allows for fine-tuning of front-end alignment angles that directly impact handling, tire wear, and steering response. The 10-degree specification addresses specific geometry requirements common in lifted trucks, performance street cars, and off-road competition platforms where factory a-arms fall short of tuning capability.

This 11.5-inch screw-in design offers adjustable caster and camber correction without requiring complete a-arm replacement—a significant cost and labor advantage over solid-arm alternatives. The screw-in mechanism allows field adjustment by simply rotating the threaded stud, enabling you to dial in precise angle changes that compensate for lowering springs, lift kits, or custom frame modifications. At 4.94 pounds and measuring 13.75 x 1.75 x 14.2 inches, the component integrates into standard a-arm cavities, and the robust construction handles the stress cycles inherent in both street and track duty.

This ball joint suits mechanics and enthusiasts performing suspension geometry correction on independent front-end platforms where caster or camber adjustments are essential. Installation requires standard hand tools and basic suspension knowledge—unload the vehicle, support the frame, disconnect the tie rod and control arm, then thread in the new ball joint and adjust to specification using alignment equipment or a ride-height gauge. Verify compatibility with your specific vehicle's a-arm bore diameter and thread pitch before ordering, and always recheck alignment after installation to ensure optimal tire contact and steering feel.
