The JL Lean

[3TV]

We all know that JL's tend to lean to the right with aftermarket suspensions. What have you done about it? My last JLUR had Eibach springs and King shocks, and after installing MetalCloak skids it leaned to the right badly enough that the right side fenders were 1 1/8" lower than the left side fenders. The Eibach springs were too soft, and even after adding 3/4" spring spacers on the right side it still had some lean to it. My current JLUR 392 XR has a MetalCloak 2.5" lift, and the right side fenders are 3/4" lower than the left side fenders.

Jeep builds these JLs with different spring rates for left and right sides, to compensate for the uneven weight of the fuel tank on the right side. Synergy says that they have different springs for right and left sides, but I don't know of other companies that go to the bother and expense of doing that. So we end up with the JL lean.

I had held off on getting the MetalCloak skids on this Jeep because I wanted to avoid the lean that the heavy dual gas tank skids cause. I thought maybe spending twice as much for the Next Venture aluminum skids that let you remove the stock steel gas tank skid plate, and replace it with aluminum, might be worth it. But my Jeep already leans, even with just the stock skid plates, so what is the point? Just get the stronger and less expensive MetalCloak skids and fix the lean afterwards.

What are people doing to fix the lean? I guess all there is, is to add spring spacers on the right-hand side. I thought about calling MetalCloak and ordering just one of their 3 1/2" springs for the right front and one for the right rear. Then running 2 1/2" springs on the left side and 3 1/2" springs on the right side. Anyone do that?

Anything else that can be done?

Driver weight is a consideration.

Just sayin’.

Thats it then. I just need to eat more potatoes and pasta.

I’m going out on a limb here to say that’s something way more than pasta and potatoes…

Too though, JL’s have slight leaning more so when gas tank on passenger side is full. But there are tons of variations to cause a lean.

Clayton uses different rear spring rates for this reason. I know because I put them in backwards the first time.

My Jeep has the very slightest lean but it's barely noticeable unless you're looking for it.

When I installed the metalcloak 3.5" springs, I trimmed the factory top spring isolator and stacked it on top of the new mc isolator on the passengers side up front. Jeep now sits 100% level with just over a half tank of fuel.

Not surprisingly, I've had the "lean" even with 3/4" spacers on my rear springs and nothing else. The mystery is why this only happens with the addition of a lift and not the stock configuration by itself. I've even had both rear springs replaced with new OEM springs, and the problem still persists.

Offroad shops and Jeep dealerships in my local area can't explain it, but tell me that it's 100% safe to drive this way. I suppose they are right, but my OCD can't ignore the obvious asymmetry and it frankly drives me a little nuts. So...just hoping that somebody here can explain it and perhaps offer a solution. Thanks in advance and happy leanin'...I mean, Jeepin'!

My RK lift comes with the rear passenger spring perch a half inch taller, and I put a teraflex half inch spacer up front….no fux given that it might lean when I’m in it, I can’t see it….?….my own ocd is a real bitch…….

I sometimes think my Jeep leans, but in the three years I have owned it I have not found any flat ground to park it on.

AEV lifts come with shims for the passenger side springs.

Mine had lean stock and lifted. Shims and spacers helped with my OCD.... I mean lean.
