Determine my EXACT Lift

Is there an easy way to determine exactly how much lift my TJ has?

Maybe measure from spring bucket to spring bucket? But, I need to know what is the stock dimension.

I have a 2" BDS lift with 1/2" spacers up front and I think I re-used the little 1/4" spring rubber ring also. But, it's been on for 5 years and may have sagged. I need new shocks and so I'm trying to determine my front a rear EXACT lift.

It might be 2"...but it might be 3"

Any suggestion on where to take some measurements?

If you know you have 2" lift with minor spacers, I would just get +2" shocks and don't over stress about it.

for purposes of buying shocks, we'll just say you have a 2" lift.

the bigger problem when you buy shocks is making sure the compressed and extended lengths are appropriate for you - which doesn't necessarily correlate with advertised "lift height". and making sure you have enough bumpstop extension to prevent those shocks from bottoming out and causing damage.

The way I heard to determine lift is measure your front coil springs and subtract 12 inches. Although I am not sure all TJs/LJs come stock with the same ride heights.

These measurements are from the bottom to the top of each spring, with the jeep on level ground, full weight being applied.

Welp, I went through a bunch of posts about shocks, lifts, and bumpstops. My brain hurts but I have learned a lot.

I'm not done researching but I'm a little closer to getting my new shocks. I may get one of these three for the front...

OME N66 (13.2 - 22.4)
Bilstein 24-186810 (13 - 21.8)
BDS 55979 (13.9 - 22.9)

OME seem to have a nice range and I wouldn't need bump stop extensions.

I'm not sure about the rear yet....I wanna check the axle movement first.

Plus, I'm thinking about a 1" body lift and 1" MML. That will help keep bump stops shorter and also give me a bit more clearance. That might make the rear selections a bit easier.
