'91 PZJ77 Suspension

CanuckMariner · 10-29-09, 09:23 AM

Looking for a new suspension as mine is quite weak (~20 years old) and has a bit of body roll (stock I suspect).

Anyone know if OME makes a system for this truck and if so, where in the catalogue it is? Part numbers? What other trucks have equivalent leafs?

If not OME, what do you suggest? I have found that Dobinson of OZ has them but no N. American reps and very expensive once they get here.

Any help is most appreciated.

As far as I know OME never built a kit for the 77. My PZJ77 had been lifted prior to me purchasing it, but seller said that he bought an OME kit and installed everything but the main leaf. I think that the spring eyes are longer than that of a BJ70. Sorry I dont have much for details, but hopefully some of this info will work.

The front springs are the same as BJ70,but the rears are longer.
Dan at 4wheelauto lifted his 77 with OME springs.
l use ZEAL springs from Japan.

I figured as much, thanks!

Spoke with Dan yesterday and he used the main stock leaf (eyelets) for the rear and the rest are 75 leafs.

Still figure the 76 series should work but no confirmation.

umm, i want you to think this through.
IF the 75 series springs did work then they would be listed as fitting the 77. you will need to fabricate your own rear lift.

Dobinsons list the front as being the same as a HZJ75 but the rears seem to be on their own.
They list the rears on the new 76 being the same as a 77

I figured as the 77 was never sold in OZ (Japan only, I believe) that OME would not have anything about the 77.

Catalogues

That the same thing I was thinking but no way to check for sure unless one knows someone with a 76 to confirm measurements.

go measure the rear springs eye to eye center and then make a call...

Dobinsons are big enough to research the info. Much of their product is exported and I would bet they have it right

I agree with you! and thanks for the info.

A late model 76 is about 24 1/4" from the fixed pin to the center and about 31 from the centre to the shackle. The stock pack has 5-6" of camber.

There are *J77s running around with OME suspensions so it is just a matter of finding the part numbers. Was Airlocker USA no help?

Could have sworn I answered this once but can't see/find the post. No ARB was of no use.

However, Dobinson (OZ) was kind enough to confirm the 76 rear IS the same as a 77 rear, just normal 70 series shackles. Will oder the 76 rears and 73/74 front leaf. So no need to custom build or use a 75 as suggested.

Thanks RoscoFJ73 for keeping me on track.
