After reading the threads i decided to go with a 2"Rc lift. i also ordered spidertrx spacers and im going to be putting 265/70 toyo m/ts. today i got the lift and it measures 1.75" both the front one and the rear one. i ordred 2 pairs of rustys spacers to make up for the nose down of the jeep. it sits 2" lower in front than the rear i already double checked it. So the question is what to do. i was thinking of just installing the fron RC spacer on the strut just to level the jeep but don;t know if tires will fit. or install the RC front lift with 2 rusty spacers on each side but im still going to be 1" shorter in front. i wonder why my front end is 1/2 lower than most commanders what could be the problem could it be the stuts or somethng?i have a 2007 commander limited 4.7.4x4

You didn't read all the threads.
Because the front strut/spring assembly attaches to the lower control arm at approximatly mid-point, the lift ratio is about 1 to 2.
For example, installing the 1/4" plate above the strut mounting plate will realize approximatly 1/2" lift.
As more spacing is added, the lower control arm drops, and as a result, the ratio becomes less.
The levelling kit I make adds 7/8ths to the assembled strut length, but because the lift ratio changes, results in 1 1/2 lift.
If the 1 to 2 ratio was constant my 7/8ths would result in a hair under 2" lift.

BTW What are you using for measuring points to come to a 2" rake?

Your only going to want to use one pair of rusty's spacers for the front to make up for the nose down. That should even it out nicely.

Like robby stated, for the front your going to get about double the amount of lift then the actual thickness of the spacer. However for the rear youll get the exact amount of lift as the spacer.

It sounds like he already received the RC lift.

The RC lift leveled my Commander out all by itself.

Have you actually measured from the ground to the fender flares?

Quarter-inch lower in the front. That could be tires, too, more weight in the front.

It was obvious from a visual standpoint, however, when I got it installed. Before the vehicle had an obvious downward nose, and when I got it back, it was practically leveled out.

Found a pic that best shows the "levelness". Again, quarter-inch difference on level ground, but you can hardly tell just eye-ballin' it:

i have the RC 2"...i went over board on the spacers but after installing the lift i calculated it out and if the install the Rusty's leveling spacer up front it will level out the commander with a 2" lift
