I am running a 3 in FT ultimate lift with 35 in tires. I would like to go to 37 in tires next. I would like to use as much of the current lift as possible but gain a inch or so to clear the 37's. Has anybody tried the JKS ACOS adjustable coil over bumpstops on the front instead of replacing the spring and being able to dial in the height? I would probably replace the rear springs for a 4 in.
I know I wll need to replace the shocks also.
What do you think?

 

Anybody running these on the front or back? I hear they are great but would like to hear from those using them.

Thanks

 

I had a weird 1 3/8" sag on the RH side. My springs were within 1/4" under load and could not figure it out. I finally went with the ACOS front and rear. It allowed me to level the Jeep plus give it a rake to compensate for the gear I carry on the trail. At minimum, the front will give you 1 3/8" lift and the rear 2". It's basically an adjustable spring seat that allows you to set each spring at the exact height you want.

 

hi I'm running the jks acros pros with the nitrogen bumpstops.. i am very happy with them.. give you adjustably from 2 -4 inches.. so you can find tune and level everything out .

 

Very nice rig!

 

Are there any draw backs to usng them front and rear? Any issue with the rear springs wanting to come out of their seat during extreme flex? It looks like they add a tower to the back similar to the front which I would think would help realign the top if the flex let them unseat.
What about replacing shocks to compensate for the added lift?
If you use them at all four corners, and wanted to run level at minimum lift you would run the rear at minimum, 2 inches, and extend the fronts one inch beyond their minimum, providing 2 inches of lift?
The approximate cost of $250 listed on Northridge is that per corner or for a set?

 

I put mine over the 2" OME lift. Then I got some LT OME shocks from David. The rear ACOS come with rear spring retainers to take the worry out of losing the springs. To level front and rear, all things being equal, you'd bump the fronts up 5/8" over minimum. Look for me around town -silver unlimited, Eugene the Jeep deacal on the sides with the Offroad Heros top to get a closeup look at them.

 

Thanks guys, Did you run into any issues setting up the rear pinon angle for the driveshaft and getting the Acos bumpstop to line up correctly?
I am thinking the ACOS front and rear with new shocks. That will put me at 5 inches of lift for the 37's. I just replaced the front DS with a Tom Woods and hope that will still work. Also just replaced the front brake lines, not sure if they will work or not. I would like to run without replacing the rear driveshaft for awhile. Probably will need longer rear brake lines.
Seer 1: For some reason I have not seen you around....? I am not in town alot since I work out in Grandview.
