QA1 GM Large (K5208) +1.000in Stud Upper Bolt-In Style Ball Joint

QA1 is known for making well-built suspension components, and this Ultimate Ball Joint is a great example of their work. If you're working on a large GM vehicle from the 70s, 80s, or even into the 90s and early 2000s, this upper ball joint is designed to give you precise control over your suspension geometry. It's a bolt-in style, meaning it's made to replace your stock ball joint directly, and the extended stud length is particularly useful for fine-tuning your roll center or making geometry changes without needing to swap out entire components.

What really sets this ball joint apart is its patented, self-lubricating design that's also 100% owner rebuildable. This means you can adjust the preload to achieve completely smooth, bind-free operation, setting the breakaway torque as low as you need it. The precision ground 52100 bearing steel race ensures even load distribution and long life, so you can count on consistent performance. Plus, you don't even need to remove the ball joint from the car to make adjustments, which can save you a lot of time and hassle.

This ball joint fits a wide range of large GM applications, including models like the Chevrolet Camaro, Impala, and S10, as well as the Pontiac Firebird and LeMans. Because it's owner rebuildable, you can keep it running smoothly for a long time, and replacement parts are available at reasonable prices.
