Overall Assessment

Customers appreciate the product's quality and practicality, notably its excellent build and the right fit with Camaro tubular uppers. It also adds extra height. It delivered exactly what customers needed for their street stock, affirming its usability. However, some inconsistencies were found between two ball joints, believed to be from different suppliers. A minor adjustment resolved the issue, revealing the product's adaptability. The fasteners and the gland also witnessed a significant, 30% quality upgrade, setting it apart from competitors.

Fit great. Had a slight issue getting the nut to start due to a bent threat, but was able to get it to finally go on properly.

Good price, will see how they hold up. The two ball joints were slightly different, probably from two different suppliers. Rubber boots differed and one didn't sit squarely in a-arm. Minor beveling of a-arm fixed it. Both had same dimensions otherwise.

How much "taller" is this ball joint than its stock version? Also will this ball joint require me to ream my 2nd gen fbody spindles even though they are already at a 10° angle? will these ball joints bolt into your tubular control arms part #91034397 it says to use a k6024 ball joint with a 7° tapper. I want a longer ball joint shank to increase my negative camber gain. Thanks.
