Customers say

Customers highly appreciate the product for its quality, usability, and practicality. They mention the product is great for adjusting ride heights, and most found it easy to install. Users have reliably used the item in varying car models and applications, from racing vehicles to street rods. The feature of easy adjustability without having to disturb the entire suspension was praised. Users recommend it over alternatives like rubber coil spacers and air shocks, noting it performs superiorly. The product is perceived as a cost-effective solution until one can afford coilovers. Material quality stood out as robust, and it was reported as working wonderfully, delivering expected results. Some suggested a lock-ring or stub screw inclusion could enhance the product, facilitating installation.
