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.

Used this to raise the front end on my 86 Monte Carlo SS with Drop springs. You need to bend the tabs in the spring pocket to have it sit flat, but it works until i can save up for coilovers.

I purchased these to raise my 68 Camaro w/2" drop spindles on stock A-arms ~ 1". My coil spring ends are very pronounced (not flat). Should I be concerned that top A-arm spring perch alignment pocket to accept pronounced spring ends will be eliminated with the flat spacer? Maybe create a pocket in spacer or cut top of spring flat to match flat spacer? Other alternatives? Don't worry about it?

Inside diameter ? I know it says 2 7/8" center hole for a stock location shock if this is used in the front, can you verify that this is correct? In the picture it appears to be sitting on a 5" rear spring and the hole looks small. Thanks
