MU leaf springs - Tough Dog or Ironman

Postby Justsomedude » Fri Jan 05, 2018 8:49 am

Hi all, I'm a returning MU owner. Had one about 15 years ago and should never have let it go. Anyways, I'm back in the fold now and restoring/modding a '91 MU 2.8TD I've picked up.

To the point. The previous owner has managed to install what look like springs that are too long in the back, the rear wheels are significantly off centre in the arches. So thought I'd kill two birds and get the wheels back to centre and get a little lift at the same time.

I've trawled through all the posts I can and it looks like Jackaroo/Rodeo leaf springs are a direct fit ? Please correct me if I'm wrong, going to be painful to return them after I order them!

I can get either Tough Dog or Ironman for around the $500 here in Tasmania. Both are meant to be 0-300kg (their lightest ones) and both claim to be 45mm lift, so it'd come down to the brand I guess. My MU will be mostly empty or very occasional camping trips so don't want HD and may have to remove a leaf as it is to get a decent ride.

Any thoughts which way to go? Thanks

Mu springs seem to be a major drama. I would measure the front pivot to the top shakle pivot and see id they can verify that the springs are this length under no load. That would see the shakle pretty much vertical with no load and about a cm back loaded

Thanks and will do. The Ironman vendor assures me the springs he has are good for a MU - so that's a +1 for them, and they're in Hobart. The guy from Dobinsons gave me a figure of 553mm from front eye to center pin (ubolt). Wondering if I can reverse the current springs now, as the centre pin is off centre (currently towards the back). The front bush seems to be pressed in but might move with a sledge - worst case is I replace the springs either way.

I'm going to order the Ironman leaf springs today, mainly cause its from a local supplier. Might have to take a leaf or two out no matter what springs I buy from the sounds of things, they're all setup for more weight than an empty MU bum.

While I was taking my springs off today I thought my front spring mount (for rear spring) looked odd, is this normal or has someone 'modified' it for a bit of lift ? It's like it's got 2 sets of mounting holes in it, one set about an inch higher than other - or am I missing some part from there ?
