Questions & Answers

1 Question • 1 Answer

Leaf springs are worn out on my 57 chevy 3100 pickup. Looking for an easier fix than replacing leaf springs. Will this coil over eliminate the problem of "bottoming out" when hitting bumps? Is it just a matter of pulling out the current shocks and installing these in their place?
