I bought these a few years ago and never used them. Cleaning up the garage and thought I should offer these on here. You can simply twist these rear shocks to change the valving. If the shock is on the vehicle you simply un bolt the bottom bolt and rotate the body till it clicks to change the setting. 3 settings. They fit 64-72 A body’s so Skylarks for sure plus others. $100 shipped anywhere in the US or Canada. Just the rear two shocks
Hi, no these shocks adjust so that they change the car acts as you launch from a stop. Each setting changes the valving in the shock so it compresses and rebounds quicker or slower. Depending on the car or the track conditions one setting may work better than another on a given race day.
