4" rough country w/ 2" spacers?????

I've got a buddy looking to sell a 4" rough country lift and would like an easy way to run 35's without spending money on a bodylift. I currently have a 2" BB and wondered what you guys thought of running the 2" spacers on top of the rough country lift.

4" is about the limit for a properly functioning/ decent riding, short arm suspension. After this point the control arms are nearly vertical, and instead of absorbing bumps and flexing, the control arm will just push up on the frame, resulting in a horrible ride.

My recommendation is to sell your budget boost and invest that money in some quality shocks (which you will need bc rough country shocks ride very stiff) Then add a one inch body lift to that 4" RC lift and you will be ready to clear 35's.

6" of lift on a short arm? Not for me. I'd bet you could sell your BB for enough to buy a BL. IMHO

damn....you beat me to it

Control arms angles would get too steep with the RC short arm lift.
You could probably get by with 3/4" ontop if you need it.
I have SA's and like them. I might do it down the down the road if I need the extra clearance.

a friend has a 5.5" LA lift and a 2" BL and the 35s still rub.
if you want good flex and offroad capabilities you΄ll need more than 5" (4" coil lift + 1" BL) for 35s.

Your friend needs to adjust his bump stops then. With that amount of lift he should be clearing 37's.

My approach is to usually keep a low COG and still have room to flex. If he installs 35's with about 5" of lift and sets his bumpstops accordingly, this (in my oppinion and taste) will give him a good balance of height/ground clearance/ flex without being too outrageous or unusable.

first he installs an expensive 5.5"longarm lift for better offroad capabilities and then he extendes the bumpstops what decreases these capabilities? does that make sense?
i don΄t think so.
but he will install some other fenders, after that he will have enough place for the tires.

With any lift installed on a wrangler (whether they are cheap or expensive) the bumpstops should be replaced or adjusted accordingly. The purpose of a bumpstop is to limit the UPTRAVEL of the suspension to where it will not hit the fender. By doing this, you are not decreasing cababilities, you are simply saving your fenders and tires front contacting.

If your friend with an expensive 5.5 longarm lift and 2" body lift is still rubbing with 35's, you should probably adivse him to properly setup his bumpstops. Every piece is crucial to making the entire suspension system work properly.

I'm running a 4" RC and 3/4" Tereflex spacers with 315/75R16's with no rubbing. I would not go any more that a 3/4" spacer. If you do you're really pushing the limits of your short arm suspension.

you should be able to tuck 35s under the 4in alone, just adjust your bumpstops and youll be fine

Before getting into the 4 inch lift, are you prepared to do an SYE and CV driveshaft install?? Does his 4 inch come with the track bars? I'm new to rough country lifts and don't know if they do or not.

Wait, you have a 35 and want to run 35s? That wouldn't be such a good combo offroad. I have 32s on a 35 and I'm scared to do anything to harm it. There's more to it than just going from a 2"BB and 32s, to a 4" and 35s. What are your gears?? Its more likely that you have 3.07s or 3.73s, also not a good combo with 35s. Sorry for my negative comments, but you have to think about what you're getting into and be prepared to spend a whole lot more. There are more underlying issues and upgrades that are necessary to run a 4" lift with 35s. Don't forget about the stronger brakes too. How will you stop those 35s??

yeah like mentioned above, your stock axles and gears wont be able to support the weight of the 35s off road. as far as the sye and cv, i didnt have to do that to mine, and i dont get any vibes at all

Don't be such a wussy. I ran the gambit between 31's to 36's and never broke my dana 35. I was prepared for it if it did break, but I certainly wasn't scared of it. Big deal you just change the axle shaft. I found the brakes to be adequete. As far as gears go if he has a 4.0L he will have the torque to turn 35's no matter what gears he has. Back before my and my firends had ever heard of the internet we were running wranglers with Dana 35's and never had a problem. It wasn't until I got online that I heard it had such a bad reputation.

To the other dude. Lowering your bumpstops does not hurt your off road ability. It in fact increases it. You really need to understand how things work before you spout off misinformation. By extending your bumpstops you not only keep the tires out of your fenders, but it also forces the oppisate tire down and makes it have better traction.
