How to Install Old Man Emu 2 in. Front Heavy Lift Load Coil Springs (07-18 Jeep Wrangler JK 4 Door) on your Jeep Wrangler

Installation Time

2 hours

Tools Required
  • Basic Metric Mechanics Tool Kit
  • Large Prybar (optional but helpful)
  • Jack and Jack Stands

Because every suspension is a little different, there may be additional wire looms, brake line brackets, breather hoses, etc that may be necessary to loosen or remove prior to dropping your axle. This installation is based on an already lifted Jeep, so all of those items have been previously addressed and rerouted on earlier installs. If you do not already have extended brake lines, now would be a good time to consider adding them. 

Installation Instructions:

1. Raise vehicle from the frame, support with jack stand(s). Relocate jack under axle. Pick one front corner to start with and after jacking that end of the axle, remove the wheel. (Easiest and recommended to do this install one side at a time)


2. After verifying that tension is off of the sway bar link (adjust the tension by raising the jack still under the axle), Use a pair of 18mm wrenches or ratchets to remove the axle side of the sway bar link. Lower axle as necessary and use the same wrenches to remove the lower bolt from shock (not pictured).


3. After verifying that all necessary brake line brackets and wire looms are loosened as needed, carefully lower axle. You will likely be able to simply remove existing spring by hand at this point.


4. Reusing rubber upper spring isolator, slide new spring into place on upper tower, and then using your favorite method of axle manipulation/spring compression, slide new spring into place on lower perch. I typically use a 3ft pry bar to lift spring into place from the bottom.


5. After verifying that the end of the spring is resting in the groove/spring stop on the lower perch, use a jack to raise axle and replace bolt through shock mount, (it is recommended to wait to torque shock bolt to spec after the vehicle is resting at ride height and on all 4 wheels). Raise axle further and reconnect the sway bar link. Now reconnect diff breather hose, brake line bracket, wire loom clips, etc that were loosened or removed during installation. Reinstall the wheel and lower vehicle. Now torque lower shock bolt.


6. Repeat process on the opposite side. Recommended pairing these springs with OME rear springs for best performance. Enjoy your fantastic new ride!
