Hey everybody,

I'm trying to figure out how much lift is on this jeep I bought a few weeks ago. I'm having a hard time understanding what I'm looking at and as a beginner would really benefit from someone walking me through this. I took some pictures. Anyone have an idea how much lift this is?

Just measure the springs and any body lift you may have.

The springs on a stock TJ were front 12" and rear 8". Anything over that is the amount of suspension lift.

E.g. If front = 14" then 14"-12" = 2". You have 2" of lift in the front
If rear = 11" then 11"-8" = 3". You have 3" of lift in the rear.

Also see if you have a body lift. There are 13 locations. The three on each side under the doors attached to the frame rails are the easiest to spot for most people. Common are 1", 1.25", and 2".

You add the suspension lift to the body lift to get the total lift.
E.g. if you have 2" suspension lift and 1" body lift, then your total lift is 2" + 1" = 3"

That's super helpful. Does it appear to you that there's a rubber spaced on top of the coil spring? Or is that just the coil seat.
 
Does that look like a rubber spacer to you on top of the coil spring?
That is called the coil spring isolator. It is a rubber piece about 0.5" thick that isolates the coil spring from the upper perch to dampen.

Thanks everyone for the insight! So it looks like the jeep has 31 inch tires and a modest 1 inch lift. Is it possible that it came from the factory this way? The PO also put a winch on it, which I only thought was helpful if you were doing serious off-roading. In which case, wouldn't 33inch tires be more appropriate? I'm just trying to understand what this jeep is best suited for so that I don't get in trouble off road. Any commentary is welcome 🙏🏻
 
Not without 3 more inches of lift,regearing,sye and some other things.

A winch can be helpful anytime something needs pulled.

Your jeep did not come factory with a lift

Your next homework is to find out what axle gearing it has

That's a great question. So I took a look at the build sheet of course, but I also know that there's a detroit autolocker in the rear. So I think it's possible that while they were in there they re-geared it. However I figure they probably left it stock seeing that they were only running 31 inch tires. Do you know if there's another way to check without opening up the pumpkins?
 
Your springs are aftermarket. They were likely 2" lift springs and are sagging due to the weight of the winch, age, etc. Although there may be some silver 1" lift springs out there, the only 1" springs I've seen are the H&R springs and they're not silver.

As for determining gearing, Is your speedometer correct? If so, what's your engine RPM at 60, and what transmission do you have? Another is to rotate a tire with it off the ground and count the driveshaft revolutions, or vice versa.
