OME rear leafs too short?
« on: Apr 27, 2018, 06:47:32 AM »
I recently put some OME leafs on the rear of my '80. They are the 2" lift leafs and when I got everything back together, they were short and the shackles pointed towards the front of the truck. I was told to put a lot of weight in the bed and let them "settle" but they are still pointing down.. I've heard I should have bought '85+ rears since they're longer..



I could move the rear hangers a bit? Or do I have any other options?

Well I sure hope not. I put them on with the arrow towards the hard mount, just as I did with the front ones.

Just stock ones. Since I bought new OME I'd hate to waste money buying a whole different set.

I would move the shackle hanger forward. That's the best fix in my opinion. If you go that direction maybe consider setting it up with a shackle a bit longer than stock as well.

That brake line looks kinda tight.

Is that at full droop?
Tight brake line says yes so what's it look like with full weight on the springs?
Is eye to eye measurement the same/similar to what you took off?

They do look short. Do you have the axle on jack stands the weight of the truck on it? If not you have the frame supported and axle hanging from springs which is the exact opposite of what we need to see.

I ask cuz it's happened before. Were there directions included that said which way to mount them?

Pull a straight line from eyelet to eyelet. Then go check your old ones.

I went off the ARB website. They said the leafs have a yellow mark on the side that goes to the hard mount (non-shackle).

Yup. The truck has been on its tires for a couple of weeks now and had extra weight in the bed to help "settle" them.. The shackles still point down, not slightly back.

Yeah I seem to have put them on correctly.

You have them pointing the right way.  Mine look like that unloaded but with the bed on and a little weight they are almost 90 degrees, still not the angle I want.  I guess OME makes them a little shorter length to help them be the right shackle geometry when they are loaded down.   I carry a 200 gallon water tank twice a week so this was desirable for me.  I may end up taking the to two stock leaves from my old packs and replacing the top two emu leafs if I don't like it.  I have seen pics of them on 1st gens with a little weight and some miles though and they look more acceptable.  I am in the same boat as you so I hope they work as is. I haven't got a chance to use the truck yet though as I don't have my t-cases or drive lines in.  Soon I can give you some real feedback.

Can we see a pic of them with the weight of the truck and a couple hundred pounds in the bed on them?

Here are mine with the bed on, bumper and a spare tire and some junk in there...

Oh and the longer rear springs start in '89 for our US pickups.  The '85-'88 pickup rear springs would be the same as you got.  The center pins are in a different location so I'm not sure they would work that well on a 1st gen without moving the rear front hangers.

Gotcha. Yeah, I had quite a bit of weight in the bed for a while and they looked like yours in the photo. I should have my new engine soon and be able to drive the truck and we'll see how it goes.
