Calculating Lift Height...?

Have yet to find a good answer so will throw it out there...

Does anybody know how to calculate what height your lift is?

My lift is completely homemade and I get the question all the time of how much lift I'm running. No idea how to figure it.

I'm guessing maybe locate another '03 TJ that is still stock and measure the height from the axles (front and rear) to the frame then compare to mine and figure the difference.

Anybody have suggestions or web sites that might help?

I would measure from the center of the wheel hub to the bottom of the transfercase skid plate. That would be the part that hangs the lowest.

I read some where that rating lift heights shouldnt be based on one number. And that it should be based on a set of numbers. And i would have to completely agree.

a set of numbers that should be important should be angles of approach and departure, ground to lowest point under the jeep, and ground to axle. numbers like that mean a lot more which im sure you are well aware.

Sorry i didnt help answer your question.

I think maybe the difference between stock wheel center to a point on the fender and the center of the wheel and the same spot on the fender with the lift.

the first picture has to do with springs, and the second is two screen shots i took from roughcountrys youtube video on their 4 inch lift. Hope these help.

That would likely work if I still had the stock spring buckets and fenders. Both are long gone. Thinking center of axle to the frame would (hopefully) be best.

'cause I'm OCD and don't really like having an unknown in the rig. Yes doesn't change anything, but piece of mind is a good thing

New guy with comment;

It seems to matter because when i go to buy shocks, they want to know how much lift there is. just my 2 cents.

You should be buying shocks based on shock travel not suspension lift anyway.

Another reason to know is for the FAQ by other gawkers. "How much of a lift is that?" Sucks to be honest and say, "I don't know...maybe 3"-5".

I am looking at new shocks online through quadratec. After choosing the model and year, they ask how much lift.

Measure from mount to mount at full droop and at full compression.

Thinking probably closer to 6-8", but therein lies the question...
