JKS Manufacturing Front Adjustable Coil Spacer - 2007-2018 Jeep Wrangler JK

By design, coil springs are more sensitive to load changes because they lack the inherent friction produced by leaf springs. As a result, simple modifications like installing a bumper, winch or second battery can easily affect vehicle ride height enough to create tire clearance problems.

Poly spacers are often used to improvise, although not recommended due to a lack of proper sizes and abundance of inferior designs. And purchasing new coil springs to compensate for each modification simply isn't practical, yet most Jeep owners have had no other choice...that is, until now!
