4" Rough Country Lift - 2" unlevel?

Installed the lift on my brothers stock 92 YJ that was sitting level from start. Now that lift is installed the front droops down at least 2". Called RC and they sent out another set of springs and still the exact same thing. Any one else have this problem?

Does he have a heavy after market front bumper and a winch? Anything to cause extra weight in front?

No, it is completly stock. Just doesn't seem to be sitting the right height. We have to jack the front end up about 2 plus inches to get it to be close to level front to back.

Any chance there were different shackles front VS back???

Take the springs off and measure there lift and make sure they are all the same. Just run a string through the eyes and measure from the string to the highest point of the spring arch, should be the center of the spring at the pin.

Will give this a try. The shackles are the stock ones front and back.

Have tried everything including second set of front springs from RC. Have spoken with marketing manager from RC who says it is the back that is to arched and we should be able to hang off them and straighten them out abit to level things out. I still think it is the front springs. We only have 1 inch of gap between the stock bumpstop and the new bumpstop that RC sent with the kit. Can someone tell me how much room they have between bumpstops in the front?

What size tires does your brother have? It looks to be sitting a bit high in the rear. Maybe they sent the 6" springs for the rear?

By chance, did you put the front and rear springs side by side before the install? To see if they had the same arch?

Those are the stock 30" tires. He has 35s for it when we get the lift figured all out. Just starting the build and having a hell of a time with this lift.

Had all the springs laying together and didn't notice one arched more then the other. We must be doing something wrong. We have checked to make sure the springs are not turned end for end or have the wrong springs on the front vs rear. Not sure what else it could be.

I have looked at alot of pictures of YJs with the RC 4" lift and none of them sit like this.

A body mount is only 1" so I don't think that is the problem.

i think its your shackles, look at the last picture of the jeep:


Your rear shackles are straight up and down at the far end of the leaf spring, however the shackles at the front of the jeep are at an angle. If the shackles are the same length this will cause the height variance you are experiencing.

they could have sent you springs for a four cylinder jeep, the heavier six cylinder will compress them more, im not sure if they make different springs for the different engines, its just a thought i have the same lift on my yj and i had no probems, Here's a picture of mine on 33's.

I know this might sound silly but did you install the lift and torque down the bolts while it was still jacked up, or did you put it down on the tires and then torque the bolts down? I have a buddy who torque his lift down while still jacked up off the ground and had the same issue.

I was thinking the same thing. I have an RC kit installed and everything should be tightened up after installation. I would focus on the shackles as something doesn't look right up front. They really should be hanging downward and not an a forward angle.

I recently tightened up all my suspension and found a rear shackle plate turned outside in.It was limiting its travel range by rubbing against frame. Just a thought. Also found both rear shocks bad,and front ones were not even for the lift.Ive had my jeep for a little over a month and have had fun finding stuff like that. good luck.

I am working thru some lift issues with a 4" RC installed by the PO. The guys at RC have been helpful. After adding XRC bumpers, 33x12.50 spare and hard top my rear sagged 2 3/4". Clearance on rear 4 1/2" at top of tire. Not knowing how old the RC kit was I replaced the rear springs to find the same condition. So the springs were not the problem.
The guys mentioned using the rear shackle as a visual gage. They said it should be close to vertical. Which looks true because if I take all the additional weight off that is about where they end up and I'm back to 7"+ clearance above the tire in the rear.
My front has 4" clear at top of tire. The front shackle angle looks just like the ones in the picture. I inquired from the RC guys if you could use the front shackle angle as a guide like the rear and they said not in the same way.
I too, only have an inch or so before it is on the bump stops.

Thinking of AALs all the way around to raise it back up.

Wow! Crazy! Mine was too high in the front. This is right after my 4.5 lift with soa. I had to get aal's for the back... Now my back is too high. First pic is after the lift, second is after the aal. They may be able to send you a hd one to compensate.

Is that a boomerang shackle in the front?

Not on mine. I really never understood the purpose of those.

Well I have to say we worked with RC on this and finally decided to send it all back. We then ordered a 4" lift from Rusty's Offroad. Sits level now. Will post up a full review once we get it all buttoned up and rolling.

good deal

I was working on a plan to check my caster angles and correct if needed with shims to get the positive angle needed for straight steering. Have you looked into that area yet to see the effect the lift had on your caster angles ? Just some food for thought. Glad to hear lift issue got resolved.

No we haven't had the time for any road testing yet. I hope in the next few days to be able to get this accomplished. Between work, being sick and waiting on parts seems like there is not enough time in the day.

This happens a lot with Rough Country. Granted they are inexpensive which is why people buy them, but they dont make the best quality products, so the front end will droop because of the weight of the motor with nothing to balance it out in the rear. I would suggest getting a shackle lift for your front end and keep a full tank of gas.
