QA1 Precision Products 1210-104 Adjustable Ball Joint Upper GM Large - 4-Bolt

The QA1 Precision Products 1210-104 is an adjustable upper ball joint (GM Large) in the 4-bolt style, built for racing suspensions. QA1's Ultimate Ball Joint design is strong and highly wear resistant, and the line is offered in 4-bolt, press-in and screw-in styles.

Key Features:

• Low-friction operation: Infinite preload adjustment lets breakaway torque be set as low as 0 ft. lbs. for smooth, bind-free movement.
• Wear-resistant design: Precision-tolerance ball-to-race conformity spreads load evenly, and a precision-ground 52100 bearing steel race supports long life and smooth operation.
• On-the-car adjustability: Preload can be adjusted without removing the ball joint from the car.
• Self-lubricating: Fully greaseable, with self-lubricating components for smooth operation.
• Multiple stud lengths available: Various ball studs make geometry changes easy, so you can fine-tune your roll center.
• Owner rebuildable: Rebuilding is simple, and all parts are replaceable.

Note: For hard core racing only. Not for street use.
