Service Kit Ball Joint 1.625in

The QA1 Service Kit Ball Joint 1.625in (SKU QA11210-523) is a greasable, adjustable ball joint assembly designed for suspension maintenance and repair on vehicles requiring 1.625-inch ball diameter components. This steel service kit provides the wear-resistant, corrosion-resistant properties needed for both street and performance applications where suspension geometry and ride quality depend on precise ball joint fitment and adjustability.

Built from steel construction with a natural finish, this 1.625-inch ball joint service kit is engineered for adjustability, allowing technicians to dial in suspension settings during alignment and setup procedures. The greasable design enables field maintenance without full disassembly, extending service intervals and reducing downtime. QA1 ball joint kits are recognized for precision tolerances that maintain consistent caster, camber, and toe specifications across repeated adjustments—critical for drag racing, circle track, and road course platforms where suspension tuning directly affects handling and tire wear.

This service kit is suited for builders and technicians restoring or upgrading independent front suspension systems, particularly those using standard 1.625-inch ball diameter control arms. The adjustable feature accommodates various mounting applications and allows fine-tuning of suspension geometry without purchasing multiple part numbers. Weighing 0.57 lbs with compact dimensions (4.05 x 1.95 x 6.2 inches), the kit ships efficiently while providing all necessary components for a complete ball joint replacement or service operation.
