Overall Assessment

Customers commend the high-quality and practicality of our product. Its confirmed qualities include solid material construction and fitting perfectly onto the A-Arms. The product has been described as a 'great replacement' and users have consistently expressed willingness to repurchase. However, a customer faced difficulties during installation due to shaft threading issues, suggesting a potential area of improvement. Beyond this, the product outshines competitors in quality, usability and performance. Customers notably prefer our product for its matchability with other parts. Despite a few minor setbacks, our product remains an excellent choice for many.

Big ball joint

Nice product although was delivered heavily scratched. You are required to ream out your stock spindles to fit these larger ball joints in a 70-81 camaro.

Threads on shaft stripped while installi

Can't recommend this one. The price is right, and the ball joint itself looks big and beefy, but the threads on the shaft stripped while bolting it up to the spindle on my IMCA modified. I was using a short open end wrench and it wasn't remotely tight when it stripped. The nut would not unthread and I had to grind it off. Whoever is making theses, their machining is decent but their metallurgy is terrible.
