Height of your 73?

[fossilcruiser]

I am contemplating a new suspension set up, for my HZJ73 but have some height constraints that need to work within. To gather some data, I thought that I’d poll the group of 73 owners to see what tire/wheel and lift combination yields what max height of the truck.

Hopefully this might be useful information for others down the line. Thanks!

For example, mine is:
255/85 R16, unknown suspension = 7’0”

285/75r17, soft top unknown suspension= 81”

I’ll re-measure when hardtop is on.

285/75r16 - Dobinsons 2” lift - 82”-83”

Any other 73 owners out there who can chime in?

315/75R16 - Dobinsons shackles with OME springs. 85-86"

33/10.5/15
Unknown Lift but with Iron Man Stabilizer that looks the same age as the shocks-- so maybe an Iron Man lift?
80"

Hello,

OEM suspension, 31 x 10.5 x 15 in. tires: 80 in. or 2.03 m.

Same on mine
EDIT:
31 x 10.5 x 15 in. tires
Front frame clearance: 54cm (21")
Rear frame clearance: 61cm (24")
Hub to fender (front, fender flares): ~57cm (22.5")
That's 64mm (2.5") of lift

I think we should all add hub to fender measurement as that will help people understand or figure out how much lift they have.

Hello,

I forgot to mention that there is a simpler way to find out about suspension height.

It is possible to measure the clearance between the front frame rails and the rear frame rails. The rear is around 1/8 in. or 2 mm higher than the front.

Depending on the tires, clearance varies between 18 1/2 in. or 471 mm and 19 3/4 in. or 501 mm.

Using these values, a 2 in. lift will increase the clearance by 20 1/2 in. or 521 mm and 21 3/4 in. or 552 mm, respectively.

This is where the measurements are made.

The clearance values for stock suspension and stock tire sizes are below.

Hope this helps.

LJ73 (yes, a coiler)
255/85 R16, unknown, 1.5” lift, ~80”

Here’s my BJ74 measurements

Front
Frame to ground 22.5”
Hub to fender 21 3/4”


Rear
Frame to ground 25 3/4”
hub to fender 23 1/2”

Looks like 6’6” (78 inches) is not gonna happen with any reasonable lift/tire combination. I had a BJ70 before and didn’t realize that the FRP would add to the total height so significantly.
