If someone were to buy a Jeep that has a "brand unknown" lift kit & wanted to measure how much "lift" the kit actually provides; how could you properly measure that?

I honestly do not know if the lift on my Jeep is a 4", 4.5", or 6" lift. I need to get new shocks for it soon & want to make sure I get the right height of shocks.

Thanks again guys,

Not sure, you could always pull a shock off and measure it fully extended. Then look up shock specs for different length shocks and see which one has about the same fully extended length.

Ok, I'm going to try to rephrase the question.

How would one measure to know what type/size of shock they need to order for a vehicle with an unknown lift?

Basic way would be to take the shocks off and fully the compress one side of the axle against the bump stop- measure from mount to mount. Go to other side where it's at full droop (tire should be off the ground so you know it's at full extension)- measure mount to mount.

Awesome link!!! Thanks :dance:

One question ... would this work for leaf springs as well???
I just looked on your profile and realized you had a yj... :facepalm:
I'm still researching for you. Try to use google and type in yj lift kit measuring. That's what I'm doing now. Be right back :)

LOL ..... Thanks, that's actually what I did originally & hadn't come up with anything straight forward. I was hoping one of the fab guys would add to this as well. I really do appreciate the help :Thanx:

OK, took the measurements. They say stock height to the rocker panels on a YJ Wrangler is 18"

It measures 27" to my rocker panels & I have 35" tires (which actually measure out to 34" from the concrete) Stock tires are 29"

This tells me ... 27" (-) 18" = 9" total lift;

34" tall tires (-) 29" for stock tires = 5"

9" total lift (-) 5" for the taller tires = 4" of suspension lift :angel:

I do not have a body lift, so I am pretty content with saying that I have a 4" suspension lift now.

Thanks for the help Kevin :thumb:

The stock spring height on a TJ, from seat to seat, is 12". Any more and that's all lift. I don't know about other models, and a YJ has leaves.

Increasing the tire size from 29 to 34 inches will only raise your jeep by half the difference. The axle moving upwards is what raises your jeep and since only half the diameter of the wheel is under the axle you only rise by 2.5 inches.
so it looks like you have a bigger lift than you thought.
