Hey guys! I just installed an OME lift that I bought from a local jeeper and can't decide if it is sagging in back or not. The rock rails measure damn near identical front and back but the fenders do not. I don't know if they should be or not.

Spring numbers are:
OME617
OME619


Is it just my imagination or is the back lower? Is the hard top to blame?

Also, I added some Teraflex bump stop extensions and it seems like it would bottom out on some road bumps at speed.

If you are running stock tire size you do not need any additional bump stop.

is it healthy for the coil to be fully collapsed? Only reason I ask is my buddy without bump stops and stock tires ends up fully collapsing his coils I was looking at it when fully flexed and told him he needed bump stops but if that is not an issue I will tell him. there was plenty of space fender wise but the coils were completely squished.

measuring lower edge of fenders my fronts are taller then rear. Measuring rock rails the front is about 1/2" lower then the rear. Mine looks about like yours to the naked eye. Running a level on the rock rail shows it level.

Mr. Incredible

I don't plan on running the stock tires for much longer. Planning ahead! Besides w/o the rear bump stop the OME track bar bracket smashes the right rear shock.

TheDirtman

Depends on the coil but in most cases you don't want to fully bottom out the coils. Shocks will aslo require bumpstops if they are longer then stock. Forgot to mention that.

TheDirtman

You should raise that track bar on the axle side at least 3" for a more stable and improved ride. It may solve the bar hitting the shock as well.

Did you check your brake lines for travel at full droop? I see you are still running stock ones.

Mr. Incredible

Track bar relocation bracket is OME on the frame side.

Back to the question, anyone think it looks lower in back or am I crazy?

This is the pic I sent to ARB USA asking that question. They forwarded it to the head engineer at ARB Australia. He stated that you will not harm OME coils by fully compressing them, but did suggest that you should bumpstop to keep it from happening. I can't find the email now, but he added a bunch of numbers to prove that whatever metal they use is up to the task.

Doesn't matter what we think or whether it is or isn't. What matters is what you think. If you think you need to raise the rear a bit, add spacers.

For me, I was talked into HD coils up front (bumper and winch) and MD coils in back (stock bumper). The rear MD coils sagged very noticeably. Added an extra 1/4" to the rear, then they sagged again. Not really noticeable when I had the chopped factory flares on, but I can see it with the soft top and un-cut flares, and it is very noticeable with the hard top and un-cut flares.
