QA1 Precision Products Adjustable Ball Joint Upper GM Extended Stud

The QA1 Precision Products Ultimate Adjustable Upper Ball Joint for GM applications is a high-performance replacement ball joint kit with an extended-length stud. It is built for racing and performance suspensions where alignment and geometry matter. The extended stud lets you change front-end geometry and fine-tune roll center. Customers also search for it as an adjustable upper ball joint, extended stud ball joint or GM upper control arm ball joint.

Key Features:

• Infinite preload adjustment: breakaway torque can be set as low as 0 ft. lbs. for smooth, bind-free operation.
• On-the-car adjustability: you can adjust preload without removing the ball joint from the vehicle.
• Wear-resistant design: precision tolerance ball-to-race conformity spreads load evenly for long wear life.
• 52100 bearing steel race: the precision-ground race is made for long life and ultra-smooth operation.
• Self-lubricating and greasable: self-lubricating components help keep operation smooth and reduce friction.
• Patented, owner-rebuildable design: exclusive to QA1. Every part is replaceable, so you can rebuild the joint instead of replacing it.
• Multiple stud lengths: the range offers different stud lengths for easy geometry changes.

QA1 Ultimate Ball Joints are designed for racing and performance use. They suit drivers who want precise control over front suspension geometry and a joint they can service themselves.
