About this part

Product Details

This QA1 screw-in style ball joint is designed for upper mounting on special Mopar and NASCAR applications. You get the ball joint itself, featuring a patented, self-lubricating design that's also 100% owner rebuildable. This means you can easily adjust the preload without removing the joint from your vehicle, allowing you to fine-tune your roll center for smoother, bind-free operation.

The precision tolerance ball-to-race conformity ensures even load distribution, which leads to better wear resistance over time. It uses a precision ground 52100 bearing steel race for long life and smooth operation. Because it's owner rebuildable, all parts are replaceable at economical prices, making it a solid choice for racing applications where geometry changes are common.
