    Simple and affordable fix

    These rear coil wedges are a simple and affordable fix to bowed coils. Installation is relatively easy. Pop out your coils, place the wedges on the spring perch, and replace your coils. At first, it's a little concerning that the coil has a smaller nub to hold onto, but after the installation it's clear that the springs aren't going anywhere.

    Better safe than sorry.

    Installed RC's 2.5" coils and shocks. I didn't know if I'd need them or not. Rather waiting to find out the hard way, I couldn't resist ordering them for the cost. At 2.5 inches, your axles will pitch back a little. These kept my coils vertically straight.

    They do what they should.

    I bought them to prevent my springs on my 3 in teraflex lift from rubbing the rear trackbar bracket until I get a adjustable one work great and they never shift or slide.

    Works as expected

    An incredibly simple product that fixes bowed coils. They're easy to install, and cheaper than other options. I found that they work best with coil retainers. My Springs are now straight, and contrary to some posts on forums, I didn't gain noticeable height in the back. If you have bowed coils, this is a cheap and effective fix!
