QA1 Precision Products Adjustable Upper Ball Joint GM Small

The QA1 Precision Products Adjustable Upper Ball Joint for GM small applications is a rebuildable, greasable performance ball joint. It suits racing, street stock, and high-performance suspension builds. The bolt-in, 4-bolt housing design replaces the stock upper ball joint. Each joint is sold individually. It gives you more control over suspension setup than a standard fixed ball joint.

Key Features:

• Adjustable design: You can fine-tune preload while the joint is on the car. This helps remove slop and reduce binding.
• Precision-ground steel race: A bearing-steel race gives smooth operation and long wear life.
• Low-friction, self-lubricating operation: The joint is also greasable, which makes maintenance easier.
• User rebuildable: The joint can be serviced and rebuilt, so you don't have to replace the whole unit.
• Bolt-in 4-bolt housing: The upper GM-style joint bolts into the control arm.
• Hardware: A castle nut and cotter pin hole are part of the design. Dust boots are not included.

QA1 builds its Ultimate Ball Joint line for strength, wear resistance, and consistent, bind-free motion. The line is available in more than one stud length, so you can choose the geometry that suits your build.
