Spacer lift installed. Front sitting too high

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?
TIA

If you just lowered the XK to the ground after installing the kit, and measured it then I would take it around the block a couple of times ans see if the XK stretches a little bit and settles in to where it wants to be. May be have your alignment checked?

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.

" I next installed the left front, lowered it to the ground and it sat perfect, 2.5" and even with the rear."
From this statement it was level but after the other side was installed it's now nose high by an inch, so the rake now is reversed

I'm curious to know if he actually measured the front and back as it sits now, with a tape measure.

Spacer lifts do give the illusion that the front looks higher than the rear - when it actually is not.

I'd like to see/hear what the actual height in inches is, on a level surface, from the ground to the center/bottom of each fender flare front & back.

In other words, this distance measured (see pic below) on both the front and back fender flares.

Then you'll know without any question, if it's really sitting an inch high in the front - or not.

To me the more accurate measurement is from the center of the wheel to the lip of the flare. There are lots of different tire sizes which adds or detracts from lifts when we compare - but the center of the wheel to the flare remains consistent since the tire size is removed from the equation.

Also, the front wheel opening is bigger than the rear opening so if the ground-to-flare measurement is the same the front will actually be slightly lower than the rear. I measure the height from the ground to the top edge of the rocker just below the doors - one measurement at the front edge of the front door and the rear edge of the rear door. On mine, the height from the ground to those two points is 18 3/4" - so my XK is sitting exactly level. But the hub-to-flare measurement in the front is 22" and the hub-to-flare in the rear is 21 1/2" - the difference is the larger opening of the front wheel well.

When comparing lift heights of our XK's if we all use the hub-to-flare method we know how much lift we have compared to others. There are too many different tire sizes to get an accurate idea of lift measuring from the ground to the flare.

My 2 cents...

Posting some pics would definitely be helpful.

This thread has me concerned as I was going to order the RC lift and spacers this week. I did see one lifted XK the other day by me and the front also looked higher. It was a larger lift though. Maybe 4".
I'll prob just be running my stock tires for a while since they were just put on when I bought the XK.
Unless someone would want to buy my stock 245s. Then I may be able to persuade the boss lady into getting some larger tires. That would be nice, maybe I will post something in the for sale section after the lift gets on.

To each his own.

I have the 2 inch RC Lift and it's been awesome for me, I have no complaints.
