Overall Assessment

Customers affirm the superior quality and practicability of our product in their builds, notably praising the QA1 coil-over shocks as some of the best on the market. The product stands out for its functionality in different projects, including 36 Chevy Bobber Trucks and 56 Chevy rear suspension. Users highly recommend our product for future builds, highlighting its performance and usability. The lack of availability in certain sizes, such as 5/8" bolt size, distinguishes our product from its competitors, offering an advantage in versatility.

The QA1 coiler shocks worked great on our 36 Chevy Bobber truck. I wanted to use the heir end shocks, but they were not available in 5/8" bolt size.
