Do I need a new lift?

[Bohunker]

I have a Rubicon 4xe that has a 3.5" lift and has 37" tires on it. I have run multiple Jeep events with it and never had any issues, performed exceptionally well. This past weekend I was running some logging roads with a friend, nothing major just some big ditches and deep ruts. On every big rut or ditch, the tires would really rub the inner fenders, happened with both the front and rear tires. One fender had a couple of rivets shear off and I had to duck tape it down. The only difference between the Jeep events and this last time out is that during the Jeep events I would be aired down to about 10 PSI while this time I didn't air down as there was not really a need for it.

Up until this past weekend, I have really enjoyed my current set up, performance, and the on highway driving is excellent. Do I need to look at investing into a larger lift or just make sure I'm aired down whenever I do trails? Just looking for opinions as I am still only been wheeling for about 2 years now.

How much extended bump stop are you currently running? Stock jounces?

No, you don’t need a new lift, unless this is an excuse to upgrade.

Most likely, either longer bump stops or heat gun on the fender liner should do the trick.

I really think I'm just stock. When I got my vehicle, I just went to a shop and told them I wanted to lift it and would at some point upgrade to 37" tires. Think they just put the lift in without doing anything else.

Any lift should have included them.

Can you take two pics for me? One of the inside bottom of the front springs, one of the rear bump pads (they are outside of the springs, they'll be below the yellow jounce bumpers).

Sounds like a Twilight Zone Episode!

So you had this lift how long?

Are you rubbing on both SIDES (drivers/passenger) or just F/R on the same side?

Other than your lift do you have any other mods.

Do you have a different front swayer set up or using the OEM Rubicon?

REAR swaybar

Have you inspected you linkage (draglink Tie rod, track bar for a bend or loose connection somewhere?

Check your spring buckets and Shock connections!



Something seems to have shifted laterly. This clearly is the case if you have inner fender rubbing on one side only.

Please do not go with a bigger lift all that will do is shift you Center of Gravity, lifts beyond 3.5, simply are not needed any place I have wheeled across the US (assuming 37 tires).

It really doesn't matter what lift, who put it on, or anything else. If nothing is broken, then you only need to extend the bumpstops to the point you don't rub. Nothing else you need to consider, EXCEPT what's the difference. Who cares if you rub at full flex? Just leave it be and drive it.

 

[EchoVictor]

You need 3” of bumpstops and wheels with at least 4.5” of backspace.

 

[limeade]

You can either add bump stop, which will limit your up travel and articulation. Or you could add aftermarket inner fender liners. Some aftermarket fender liners increase clearance and could solve your problem.

Here are the pics you asked for.

Whoa, you are running bumpless.

There may be a production adjustable kit that will allow you to bump the front without pulling the coils, I know you have to drill with the MC one, so that won't do it.

I just made mine out of hockey pucks. You can jack up one size and slide them in one at a time. Drill a hole through the center of them and just slide the hardware in.

Rear, you can use any of them, they all just bolt to the pad.

I'd start with 2" front and rear, and add a third if you still rub.

Holy shit those are some really nice looking coils, and some extremely OEM bump stops. You should probably go back to that shop and shoot them!

Hey on the plus side, there's a whole lot of really cool options out there for bump stops. My personal favorite though quite a bit pricey, hydraulic bump stops!!!

If not there's a lot of companies that make normal bump stops. Though I'm still at stock height so I'm probably not a good one for advice in that realm. ?‍

I try to do most of the work on the Jeep myself and have learned a lot over the past 2.5 years. The suspension is one area I leave to people that have more know-how and experience than I do.

If you use the trick I mention above, it'll be an easy driveway add. All the bumps do is keep the tires from jamming up into your fenders and protect your shocks from bottoming out.
