This is the easy way to swap in your new 63" Chevy springs! These springs are pretty much the most desirable springs you can get in any yard for under $100 and they love to flex! This kit comes with our Frenched Chevy Spring hangers, the Wayback shackle hangers to match, and 4 - 5" Shackle plates to finish it off. The shackle hangers are really a must so you don't end up having to cut off and reposition the weaker stock ones. Add a ton of flex quick!
