  • USEFUL when making future plans for heavy bumpers and/or winches (typically adding 100lb+)

  • Can be installed with just a few tools: installation is no more difficult than a Budget Boost

  • Available for the front and rear springs on ZJs and TJs, and the front coils of XJ.

  • Adjustable in just minutes from 1.25″ to 3.00” (recommended maximum) of lift.

  • Compensate for sagging coil springs, which will invariably sag over time

  • Adjust to compensate for uneven spring heights from side to side.

  • Ultimate add-on lift for those who don’t want to swap out springs.

NOTE: At this time we don’t have any way to modify these spacers to work on the WJ, but we are working toward a solution.  We will post info as soon as we know how we are going to pull it off.

*Free shipping to the 48 states

IMPORTANT NOTE: ADDING LIFT TO YOUR JEEP REQUIRES ADJUSTMENT TO ADDITIONAL COMPONENTS TO MAKE IT SAFE. CONSULT YOUR INSTALLER FOR YOUR SPECIFIC NEEDS.

**ZJ Rear ACOS Installers: We have had an issue with the rear UpCountry springs being wrapped slightly too tight to go over the ACOS threaded post.  You can easily clearance the spring with a Dremel tool, or just simply removing a small portion of the “pig-tail” from the top of the spring with a right-angle grinder or saw.  This ONLY affects the rear UpCountry springs, so far as we can tell. -Kevin-
