Jeep Wrangler JK’s sit about 1.5″ low in the front from the factory; add more weight from bumpers, winches, and tire carriers and you may find you could use a little extra boost in the front or rear. These front coil spring spacers are designed to give you that extra boost on a budget. They are easy to install and will maintain your factory ride. These JK specific coil spacers can be used to gain 1.75″ of lift when installed with the factory spring isolator or approximately 1″ of lift when installed with the factory isolator removed.
