Exactly! I'm under the impression you need to do both the spacer and a driveline if you expect full droop on a '12 or newer. I'm thinking about trying the rancho pipe.


Oh - and it doesn't matter if you're running a 2.5 vs 3.5 lift. The exhaust issue from droop - not the amount of lift.

 

I am ordering GC ARB 3.5" for my jkur tomorrow and after speaking to matson he recommends 3.5 for 4 door and exhaust spacer. Then replace driveshaft when it fails.

 

Not exactly true. I run a GC with 6Paks and an aftermarket driveshaft. Does the shaft touch the crossover at full droop? Yes. Is that an issue? Very unlikely. Unless you are racing in the desert, both front wheels will not fully droop at the same time. With one stuffed, there is lots of clearance. I'd say the ideal solution is an aftermarket shaft and a limit strap.

I assume that anyone spending the cash on a MC (or comparable) lift, is planning to run their Jeep off-road on moderate to hard trails. The big box exhaust solutions seem like a bad idea. They all push the crossover below the frame crossmember. That means any aftermarket skid that bolts to the crossmember, won't fit. If you don't have a skid there, kiss your exhaust goodbye. Also, the bolt on products are begging for an exhaust leak.

In my view, if you want to fix the exhaust, find a good muffler shop. If you climb under your Jeep you can see how easy it would be to weld in a couple 2" sections that would push the crossover back, but not down. Can likely be done for the same price as spacers.

 

We are getting close to order up the GC lift. Going to go with the 3,5" on a 2 door. For all of you out there with the 3,5" lift on 2 doors, or even 4 doors, how bad is the bump steer? We have the 2,5" Teraflex BB with 35" tires on now and I can feel the bump steer over stock. Not bad but it is there. Just concern that with the 3,5" lift, the bump steer will drive me nuts. Thanks.

 

Im curious also. I run the highsteer kit on my current 3.5 to kill the bumpsteer. But i am moving to the mk3.5 soon and I was thinking about dropping the high steer. And running minimal bumpstops. Mk says you dont need it, so ill try it, get a good alignment and let you know if no one else does in a few weeks.

I dont always drive where others cant. but when I do, its in my Jeep. Stay muddy my friends

 

Why a 3.5"? Unless you run really heavy, the 2.5" will net 3". More than enough to run 37s.

Bump steer with a BB is a result of bad suspension geometry (2 doors are much more sensitive to lift height). The 3.5" lift will give you a good 4"+ of lift. Your money and preference, but I'd never do it with my 2 door. Unless you are running 40s, in which case, you do what you have to do.

 

You've fully cycled your lift and it's not limiting your down travel at all? That's good to know - especially with 6-packs.

I would get hi-centered on ledges and get both tires at full droop causing contact but that was on my old jeep. Was told the newer ones (3.6) were worse by mc and they recommended both.

 

you will also have to lower your trackbar back down.

 

I know i was generalizing about removing the whole setup.

With the 2,5" lift we scrape over the rocks in SoCal a lot and I am tired of scraping. That is why we want 3,5" of lift. Might go up to 37" tires when this set is done. The price for the 2,5" and 3,5" is the same, so why not.
