Never heard of a failed coil spring for a vehicle in my life but hey I'll go with it, sure there's got to be someone like you to fullfill the variety of options on this planet and even that is a problem. Ok you forgot to mention some things for all of us to respond correctly like the YEAR and MODEL of the vehicle but it's ok here a couple suggestions... : Some junkyards may get you the springs for your vehicle for about $25 dollars a piece. Also aftermarket spring set are designed for performance for some vehicles and may cost $200 bucks for a set. Then take the springs to a mechanic and he'll put them in for you.
