Hey all,
I have a significant lean in the rear. My DS rear is about 1" lower than my PS rear.

I have the SLEE 2.5" Heavy Load kit installed. This includes the SOF2RH Rear Coil Springs.

I know that one of these rear springs is longer than the other, but I actually thought it was the DS spring that was longer to compensate for the driver's weight on a consistent basis.

Then I remember that I removed my swing-outs last fall for the winter months. The tire swing-out is on the PS which might compensate for the sage on the DS. But I just noticed this a few weeks ago...

What the heck is going on here? Any ideas?

I think the rear springs are equal height.
Are they fully seated in the axle-side mount?

I'll check, but I made sure they were when I installed them last summer. I just noticed this lean fairly recently.
I know for a fact the springs are not equal hieght. Sitting next to each other prior to installation, one is taller than the other. And, I may be wrong, but I thought the SLEE install instructions mentions which side to put the taller one on.

Hows the front? Did you set the torison bars with the rear swing out on? Sometimes the torsion bar settings affect the rear suspension. Make sure you have a full tank of gas when you retweak everything.

I have a full tank of gas now, which I thought might have something to do with it since the gas tank is on the DS.
I didn't have the rear bumper when I installed the suspension and adjusted the torsion bars. The front has not changed. I did have to re-adjust the front after I installed my TJM front bumper and Warn M8000 winch. When I installed the front bumper the swing outs had already been removed from the rear bumper.
It's just not all adding up. Why would having a full tank of gas require me adusting the front DS torsion bar to correct a rear DS sag?

Thanks for the reply.

If the front is not level, the rear will either sit higher, or lower depending on the front height. (Park with a front tire in a hole, same concept).

Always level the truck with half tank of gas and nothing in the cargo area.

Spring not seated correctly... assuming the AHC is removed.

If AHC is in place you have other issues.

Your assumption is correct, AHC has been removed and replaced with OME torsion bars, OME shocks, and SLEE rear springs.


Springs are seating correctly.

Rear control arms twisted
Shock Bound up
Sway bar massively bent
Torsion bars adjusted improperly
Rear springs mis-matched

As I've mentioned, this has seemed to happen recently, which would eliminate a few possibilities: Torsion bar adjustment, mis-matched springs -- IMHO.
That being said, how does a shock bind up or a sway bar massively bend or a rear control arm twist?
I haven't been in any accidents and off-roading has been non-existent during the winter months in which this has seemed to happen. The only thing I've done to put stress on the truck as of late is trailer the snowmobiles up to the mountains...

Pull coils and see if one of them is bad. Can also check the antisway bar and shocks at the same time.

How the heck does a coil go bad? No offense, but that seems like a far fetch to me. And even if one of the shocks was bad it wouldn't allow the vehicle to suddenly droop at that corner...

Curious what the acceptable amount of difference is in rear height from DS to PS?
Click to expand...

I normally have about 1/8-1/4" of difference between the front PS and DS. Until recently the rear was always slighly less than that. But >1" is unacceptable to me when it's this noticeable.

Thanks for all the replies guys,

Coil springs can crack. Jack up the rear until the shocks are fully extended and take a look with a flashlight.

You can also try jacking the front up using the center jacking point on the "skid plate." If the rear levels out side to side, then I'd suspect your front suspension.

Thanks for the tip, Hoser. I appreciate that. I'll do that this week...

Raising the front wheels off the ground did not change anything - it's still way off.
I inspected the springs and sway bars visually and everything appears to be normal. I don't see anything obvious. I have not yet raised the rear to do a more thorough inspection...

From Slee's install instructions on their website,

"Note; Some coil spring applications include a short and long spring. The longer spring installs on the driver’s side of the vehicle."

Maybe this doesn't apply to the OME springs, but this does apply to the Slee springs.
