I have 34s (actual 33.4) and when we were offroad last week when fully flexed I had plenty of room up front but was about 1/4 from rubbing in the rear. I know OME is designed without bumpstops but they also suggest 33's and I think that with the 35's it would be tight.

I could be wrong, I have been before, ask my wife.

Then a larger lift is needed. The OME is only designed to be a 2" lift.

A 3" kit should work with 35" tires with no problems. If you get a 3" kit you should make sure that it has adjustable control arms and track bars so you can adjust your suspension properly. You will also want extended brake lines if it doesn't come with them. Most will come with bump stops.
A lot of people are running TeraFlex 2.5" kit with 35" tires and are not having any problems either.

Check out some of the lifts here. Northbridge4x4

Bump stops are evil. They rob you of uptravel.

A BL is better, as a 1" BL allows a 2" taller tire to stuff....33's fit stock...so 35's fit with a 1" BL. The BB SL or OME SL, etc, is for ground clearance, articulation and ride height

A suspension lift in of itself does not change the tire clearance except at ride height, and that the tire does have further to go up before it hits something.

If you are offroading anywhere that actually requires full articulation, you get your tires stuffed here and there.

If your tire can't stuff, the truck gets picked UP at that corner...which makes you less stable.

A PERFECT suspension would allow your truck to glide over a rock field of boulders, staying perfectly level, while the tires went up and down by themselves without upsetting the truck.

In real life, the tires climbs as high as it can, and then the truck starts riding up too on that corner or side, etc.

This can tip you over if too far off camber, etc.

Same with downtravel/droop....when the tire can't drop by itself, it then starts to pull the truck down with it, etc.

So - A bumpstop makes the tire unable to continue upwards... a bad thing.

Obviously, unless you remove your fenders, etc, the tire WILL have some constraints...so a stock bumpstop is a reasonable compromise...but raising the fender out of the way with a BL, or getting flat fenders, or other measns of letting the tire continue to rise as far as practical, is a GOOD thing.



The other scenario is for very tall lifts that use coils (Or shocks) that simply can't compress as far as stock coils or shocks allowed...the bumpstop prevents over compression damage to these items.

Long shocks with too small a travel range, or coils that can't pack tight enough, are typically what you are protecting with a bumpstop. Unfortunetly, many lift kits throw in a set of bumpstops, assuming you're getting bigger tires, and they KNOW that the SL doesn't make room for larger tires, except at ride height, etc.




Hell, large enough bumpstops ARE a lift.

Teraflex 2.5" Budget Boost + 17 x 8" wheels with 4.5" backspacing = 35" tires.

This is what I run (with 3/4" spacers up front to level it).

My only rubbing has been on the front air dam at full lock, which is junk anyway, but is flexible enough not to break or damage anything when it does rub. Easily trimmed in about 5 minutes too.

If I could do it over, I would go with Old Man Emu. Probably will in the coming months. Nothing rides like OME springs + shocks.
