Adjustable Lift Kits for Jeep Cherokee

With all the high-tech doodads being produced for suspension nowadays, it's a wonder this trick product took so long to reach the market. Delightfully simple yet strong and functional, the new ACOS (adjustable coilover spacer) from Off Road General Store (ORGS) solves a multitude of problems that coil-sprung Jeeps have suffered from. From lift to lean and sagged out springs, there is now an answer.

Regardless of which lift you put on your XJ, TJ, or ZJ, the front coils simply index into the stock upper bracket, and maybe a spacer or two will be needed to further adjust the ride height. The trouble is the addition of a big bumper or a winch will cause the front end to compress the springs, giving your Jeep a nose-down attitude. And even though the left and right sides of the Jeep are identical, minor manufacturing differences can cause the vehicle to lean to one side, as can funky lift springs or crushed spacers.

The ACOS from ORGS simply bolts in place of the upper spring isolators, and provides a new location for the springs to rest on. Many lift kits are simply an aluminum or polyurethane spacer, which spaces the coil away from the mount. The ACOS does the same thing, but allows a wide range of adjustment so that you can literally dial in the suspension height that you need, and alter it from side to side if needed. We slapped on a set of ACOS in less than an hour over at ORGS, and wouldn't be afraid to try it at home either. Check out the simplicity of the ACOS, and see if it's the answer to your coil-sprung Jeep's suspension.

On this Jeep a plastic spacer was installed along with Rancho springs to gain the proper ride height. The addition of a brushguard up front caused the nose to come down a bit too far, so a set of adjustable coilover spacers was prescribed as a solution.	The easy way to install these...        read full caption The easy way to install these spacers is to drop the front suspension. Removing the track bar bolt to unhook the track bar allows the suspension to move downward. We used a hoist and stands, but jackstands and a floorjack can be used as well. We also removed the lower arms for ease of installation. With the weight off the coils and the lower coil clip unbolted, pull the coils off the vehicle. Note the factory isolator and aftermarket spacer, both of which are removed for installation of the new spacer.

Underneath, most holders are bolted on and can be removed with a wrench. If it's welded on, you need to cut it off according to the supplied instructions.

Adjust the large ring to touch the top, back off the center bolt, and screw the ring one-half turn up. Now you can tighten the 8mm bolt for the final time.	Adjusting the lower ring to...        read full caption Adjusting the lower ring to the proper height depends on what height the Jeep was before and where you want the Jeep to end up. We measured the old spacers and adjusted the lower ring to match. If we want to change the ride height once the vehicle is assembled and back on the ground, all pressure must be removed from the ACOS unit.
Final adjustment is simply...        read full caption Final adjustment is simply tightening the bolt in the adjuster ring. Notice that new polyurethane spring isolators come with the new ACOS units. The spacers lift the vehicle anywhere from 1 1/4 to 3 inches, and you get to select what is best for you.

The ACOS is a simple unit that works exactly as planned and allows you to fine-tune your coil-sprung Jeep's suspension.
