Just installed 2.5"/2" front/rear spacer lift. Everything went together without a hitch, but the front end is now sitting about 1" higher than it is supposed to. Installed the rear and it lifted exactly 2". I next installed the left front, lowered it to the ground and it sat perfect, 2.5" and even with the rear. After I installed the right front and dropped it to the ground, both left and right fronts ended up sitting about an inch higher (3.5") than they are supposed to. Any clue what I did wrong in the "put everything back together" stage of the install? Did I do something out of order causing both sides in front to sit an inch too high?
First off, I'll reiterate what Swanny said - Go get an alignment done ASAP. It won't effect the way your Commander is sitting - but when you have that big a change in your suspension geometry, a post-lift alignment is an absolute must-do, or you will kill your tires in no time at all.
Now that being said Jeremy, I'll say this; I don't think you did anything wrong and I'll use this pic of my XK when it was stock - when I first bought it to illustrate why;
See how my Commander sitting when it was stock - with the rear higher than the front?
Most spacer lifts, like the RC lift for example are designed to be leveling lifts.
Well how do they accomplish leveling the Commander out?
Well, the spacers in the front are typically designed about an inch to an inch and a half higher than the spacers for the rear and are designed to raise the front an inch to an inch and a half higher than they raise the back - to have your Commander sit perfectly level - or very close to perfectly level.
So if you ask what did you do wrong? I would say absolutely nothing - other than maybe not being aware of what the lift you were going to install was supposed to do.
Even though it raised the front an inch and a half higher than the rear - I'd bet your Commander is sitting perfectly level - or very close to it.
That's what spacer lifts are designed to do.
