These urethane coil spring spacers fit above your springs and provide added ride height to the front of any Jeep TJ, XJ, or ZJ (actual height is 1.75"). Normally they are placed above the stock isolator to generate a full 1.75" of lift, but the stock isolator may be removed to provide a net lift of ~1-1/8" if desired. The spacers are simple to install and are a perfect match with our Nth TJ Rear Spring Relocators.
