How much have our springs sagged?

Have been toying with the idea of replacing the springs on the 80 series for a while now. With the winch, bullbar and dual batteries on the front, it has slowly sagged giving it the bum in the air look. The springs are currently 50mm lift OME all round. Well they used to be 50mm a long time ago. They are about 6-8 years old from what I can work out and due for replacement.

Out of interest, out with the measuring tape this morning to get some numbers that hopefully other 80 series owners can reply to with their measurements. I am mostly interested in heights of owners with a newly installed lift, 50 or 75mm. The numbers are as follows and are with full fuel tanks and cargo draweres, all recovery gear and tools in the back.

If you reply can you let me know if you took measurements with full fuel, and whether you have winch, dual batteries, etc. Also, who makes your springs adn were they supposed to be a 50mm, 75mm, etc lift as stated by the manufacturer.

Measurements are from the centre of the axel to the bottom lip of the guard (on a GXL).

RL = rear left, FL = Front Left, etc. Car is fitted with Polyairs on the back, but the first set of numbers is with 0 psi (same as with no polyairs fitted)

RL 562mm FL 527mm difference 35mm
RR 570mm FR 535mm difference 35mm

For those interested:
Polyairs 12 psi:

RL 570mm increase 8mm
RR 576mm increase 6mm

20 psi:

RL 575mm increase 13mm
RR 580mm increase 10mm

35 psi:

RL 585mm increase 17mm - difference to front 48mm
RR 590mm increase 20mm - difference to front 55mm and looking really silly.

Thanks in advance for replies.

What kind of OME do you have on?
I had 851 fronts and 864 rears, which are the heaviest springs OME make for your cruiser. If you dont run these, then think about it. Just having the diesel in the front would be enough to warrent the 851 spring. 864 are best with l/r tank and rear bar, but a draw full of gear would be thesame weight.
In the book, OME state weighty accessories on the front (bar/winch/batteries) gives a 50mm lift, and 400 constant kg in the back give 50mm.

Andrew,

Not sure of the spring number. I can't see it stamped on it, I assume it is on the top or bottom of the spring. You (or someone at ARB) could probrably tell just by looking at them what they are. They are the springs that were in it when i got it about 3 and a half years ago.

851 and 864 will probrably be my starting point when I put the new ones in. Especially seeing as I am thinking long range tank in the future.~

Best way to find out is to put a tape measure up against them (rear) and the thickness of the wire will tell all....20mm for 864, 19mm for 863 (200kg constant@50mm lift) , 18mm for 860 (50kg constant@ 50mm lift)
Fronts use thesame wire (17) but an extra coil is there for the 851 over the 850:-)
Send me your email addy and i will send you a photo of my springs.

Andrew,

I have 18mm on the back (must be 860's)

and the front has 8 coil's from top to bottom.

A pic of your front spring would be good. What you running in there now, still OME?
