OME Spring Question

[LCnAZ]

A few years ago I had the OME suspension installed on the 62. I don't remember which level I got. Maybe this is a clue and you guys can tell me. The bottom leaf is not in the arc. It is horizontal in its last quarter or so on each end. I suspect that means "light."

How does one change that?

I'd provide a photo, but it's still in the paint barn.

Check out the Cruiser Outfitters website!
All the info you need!
Just count how many total leaves per pack.

I have the light version but dont have the flat end you described

Richard, here is a shot of my rear OME. It’s a heavy. It’s all I have on my phone but can take more when I get back home later today.

Hope this helps. Jim.

That flat leaf is an overload leaf to prevent the springs from frowning if you pack too much weight or really flex the suspension with a lot of weight.

Aha! The photo matches mine...and the answer explains it. Thank you guys.

That's where I bought mine. He shipped it all to me on a pallet.

If they have a record of the sale, they can tell you exactly what you got.
Or/and: Check out the questions section of the 60 series OME KITS, and the details of their site.
It lists the number of leaves for the different “levels” of heaviness.

 

[89BIGBLUE]

I added the OME add a leafs to turn light packs into heavy packs.
That’s one way to change them.
Or you could remove leaves to make them lighter, but careful if they are light duty to begin with. Know what I mean?

These are mediums, CS004. The heavies have an additional leaf.

Jim, you will want to remove the steel hat channel and rubber isolator pads from this installation. They are supposed to be removed when installing a spring pack that is a different thickness from stock. The hat is designed to keep the U bolts from over squeezing the isolators. With the thicker pack, it doesn't touch the mounting plate so it can't protect the isolators. Over time they will crack and fall out, leaving the U bolts loose. ARB sells a steel bushing to center the axle on the spring pin. It's necessary when the isolators are removed.

Hmmm...I learn something everyday. My system is off a parts truck so installed it the same way. However I’ve done a handful of other sets family members have bought from Kurt and I never realized this. As for the spring pack, how many leafs make up a medium vs a heavy. Curious as I had Kurt on the phone (buying something else) and asked him about my springs. As I recall he said the 8-pack meant they were heavies. Regardless, most people who ride in my truck claim they ride like heavies. . And I appreciate the tip. Question...if I only put 4-5k on the truck each year should I worry about changing it? Thanks. Jim

I hesitate to disagree with Kurt. He is a primary source of correct information for Land Cruisers. For the OME springs, I use the number of full length springs in the pack to designate stock, medium, and heavy. This leaf is the first full length leaf after the leaf with military wrap on the fixed pin (see the red arrow). It does not have a UHMW greased slider at the tip. Two of these leaves are in the heavy; CS005, one in the medium; CS004, and none in the stock packs; CS003. CS stands for 'Car Spring'. Adding a DX1L leaf will bump up the pack to the next duty rating.

Frankie has medium packs, p/n CS004. Perhaps ARB has changed the number of shorter leafs in recent years. Here is a picture of a complete heavy kit. The rears have 9 leafs.

I would recommend removing the hat and isolators at your earliest convenience. So long as the U-bolts remain tight it should be safe.

Man...that is great information. Will get with Curt and order some bushings. I have a few installs I’ll need to correct . Thanks for the insight.

Can you please show us (who don't know...like me) what the steel hat channel and rubber isolator pads look like...maybe another photo?

 

[60Works]

This is a blurry and ugly photo but it does show the hat and isolators. There are 4 rubber isolators on the rear axle, none on the front. They sandwich the spring pack top and bottom to give a smoother ride. The hat bridges the springs and sets the amount of squeeze the U-bolts can apply to the isolators. If the spring pack thickness changes then this loading is changed. OME's lift is designed to not use these parts.

Here is a picture of the hat and rubber...and a spider.

I also found this...
So I took the opportunity to get a u bolt flip kit and install it at the same time I did the spring install...
Front and rear.
(It was a bummer, manefre increased the price after I bought the rear, but before I bought the front. It was like a week difference in time!)

Fwiw ARB used to call their rears springs Med, Heavy and Heavy Plus, in the recent years they went to Stock/Lightl, Medium and Heavy, yet the exact same spring part number and specs. We don't really get too tied up in the nomenclature rather discuss the needs and then sort out the A/B/+/-/o on a case by case.

Give us a buzz at the shop and we can quickly sort out exactly what you have, we save all the build information for kits even 15+ years old.

There are a couple ways to address the spring isolators, spacers for the isolator or the center bolt spacer. We prefer the center bolt spacer and send them out with aall of our 85+ kits, if you purchased a kit from us and need a pair, holler and we'll set you up. A bit more info here: Cruiser Outfitters
