Jeep Grand Cherokee WJ

The Jeep Grand Cherokee WJ was offered from the years 1999–2004 and was the second generation of Grand Cherokees after the ZJ model.

In this article, we will be discussing some tips and tricks on how to install a budget boost 2-inch spacer lift kit on your Jeep.

Make Sure You Have All the Parts and Read All the Instructions Beforehand

Look over the parts that came with your kit. There are two types of kits, one with just the spacers, and the other with spacers and bump-stop extensions. We will talk about how to install the front spacers first, then the rear spacers. The bump-stops will be explained as they are needed in the installation process.

Please read these instructions over a few times and familiarize yourself with the install process. The night before the installation, it might be wise to spray penetrating spray on the bolts you will remove to help loosen the nuts and make for an easier install. Remember to take your time and do things right, inspecting parts and cleaning necessary parts along the install process.

Installing the Front Spacers

Before you begin, make sure the vehicle is parked on a flat surface with plenty of space on either side of the vehicle to work on. Loosen the lug nuts on the front wheels and use a heavy duty jack under the front pumpkin to lift up the front of the Jeep.

  1. Place axle stands to support the Jeep. Make sure you do not put them on the axle tube, as you may need to drop one side of the axle to remove the springs easily. Leave the jack supporting the axle under the pumpkin.
  2. Remove the wheels from the axle and set them to the side out of the way. (Tip: You can use the wheel to sit on as a stool, as you may be sitting on the ground a lot.)
  3. It is easiest to do this one side at a time, rather than dropping the whole axle. Starting on one side, disconnect the lower shock by removing the bolt, and lower the sway bar link by also removing the lower bolt. You do not need to remove the top bolts.
  4. Now you can slowly lower the axle on the one side enough so you can remove the coil spring. You may need to do some manipulation to get the coil out, or use a coil spring compressor to get them out. Also remove the coil spring isolator, and inspect them both for damage, cracks, or wear. Make sure you take notice of how the coil seats into the bottom coil seat mount. (Tip: A coil spring compressor may help in putting the coil spring back in when installing the 2" spacers.)
  5. Install the new front spacer where you removed the coil isolator from. If the isolator is good, you can re-install them. Or you can leave them out if they're bad. Install the coil spring isolator if desired at this time.
  6. Optional: Front bump-stop installation. The included aluminum extenders are used to extend the front bump-stops. Remove the front bump-stops, and install the extenders using the included hardware.
  7. Re-install the coil. You can remove the track-bar to lower the axle even more. But I recommend you use a coil spring compressor, because removing the track-bar may cause issues when re-installing it later.
  8. Once you re-installed the coil, make sure it is seated correctly (as you noted the orientation in Step 4). Then jack up the axle so you can re-attach the lower sway bar end link bolt and the lower shock bolt. Torque all bolts to correct specifications. Check that the spacer is not pinched in any way, and the coil is seated correctly.
  9. Repeat this step for the other side.
  10. Next, re-install the wheels and tighten lug nuts hand tight. Then jack up the axle and remove the jack stands. Lower the axle all the way down. The front should now be significantly higher than the rear. Tighten the lug nuts in a star pattern until they are secured. Now proceed to the rear.

Installing the Rear Spacers

This install is similar to the front in many respects but with a few exceptions. So some steps may seem redundant.

Before you begin, make sure the vehicle is parked on a flat surface with plenty of space on either side of the vehicle to work on. Loosen the lug nuts on the rear wheels, and use a heavy duty jack under the rear pumpkin to lift the rear of the Jeep. Make sure the parking brake is not engaged.

  1. Place axle stands to support the Jeep. Make sure you do not put them on the axle tube, as you may need to drop one side of the axle to remove the springs easily. Leave the jack supporting the axle under the pumpkin.
  2. Remove the wheels from the axle and set them to the side out of the way. (Tip: You can use the wheel to sit on as a stool, as you may be sitting on the ground a lot. Also make sure you don't lose any lug nuts.)
  3. It is easiest to do this one side at a time, rather than dropping the whole axle. Starting on one side, disconnect the lower shock by removing the bolt and rear sway bar mount. You do not need to remove the top bolts on the shocks.
  4. Now you can slowly lower the axle on the one side enough so you can remove the coil spring. You may need to do some manipulation to get the coil out, or use a coil spring compressor to get them out. Also remove the coil spring isolator, and inspect them both for damage, cracks, or wear. Make sure you take notice of how the coil seats into the bottom coil seat mount. (Tip: A coil spring compressor may help in putting the coil spring back in when installing the 2" spacers.)
  5. Optional: Rear bump-stop installation. The included UHM (plastic-like) bump-stops are used to replace the rear bump-stops. Remove the rear bump-stops, and install the rear extended bump-stops using the included hardware.
  6. Install the new rear spacer where you removed the coil isolator from. If the isolator is good, you can re-install them. Or you can leave them out if they're bad. Install the coil spring isolator if desired at this time.
  7. Re-install the coil. I recommend you use a coil spring compressor, because it will aid in the installation of the coil at this time.
  8. Once you re-installed the coil, make sure it is seated correctly (as you noted the orientation in Step 4). Then jack up the axle so you can re-attach the sway bar and the lower shock bolt. Torque all bolts to correct specifications. Check that the spacer is not pinched in any way, and the coil is seated correctly.
  9. Repeat this step for the other side.
  10. Next, re-install wheels and tighten lug nuts hand tight. Then jack up the axle and remove the jack stands. Lower the axle all the way down. Tighten the lug nuts in a star pattern until they are secured. And now you should be done.

After the Installation

After the installation is done, you will need to do a few things to make sure the vehicle is safe to drive.

  1. First, walk around the vehicle and make that all sides are level. Test drive the vehicle a few miles to make sure there are no issues in driving or handling of the vehicle.
  2. Make sure you get the vehicle re-aligned. This is very important and most people skip this step.
  3. After 50 miles, make sure you re-tighten the lug nuts. The vehicle will sit higher, so a headlight adjustment might be needed.
  4. After 100 to 150 miles, you will need to check all suspension bolts and re-torque.

Questions & Answers

Question: Should I change my sway bar links on my Jeep Grand Cherokee?

Answer: This is up to you - if you want to disconnect them for off-roading purposes then yes replace them. If the stock ones are bad then replace them. But as for the lift itself, you do not need to replace them.
