QA1 GM (K6024) +.500in Stud Upper Bolt-In Style Ball Joint

This QA1 adjustable ball joint is what you get when you need a solid replacement for your upper ball joint. It's designed for a bolt-in installation and features a stud that's extended by half an inch, which can be helpful for certain alignments. You're also getting a patented, self-lubricating design that means less maintenance down the road, and it's built so you can rebuild it yourself if needed.

The key feature here is the preload adjustability. This lets you fine-tune the joint for bind-free operation, ensuring smooth movement through its range. This isn't just about a smoother ride; it's about making sure your suspension components work together as they should. The extended stud length is also a notable detail, offering a bit more flexibility when setting up your alignment, especially on vehicles like the Ford Pinto from 1971-1980.
