I'm with DLS..I just swapped out my "B" spring for another "A" spring.

To find the A and B on the springs you have to look at the part number that is on the spring. You should be able to read it on the top leaf between the pin and the u-bolts (on the rear axel). For example, my left rear spring says "CS004RA" The right rear used to say "CS004RB" Now I have two "A" springs on the rear. My rear sits high but I like that..more clearance as I load it up..But it sits almost level side to side. It was over a inch low on the passenger side.

The handling is way better no more diving into left hand turns.

The photo shows my old (less than one year about 2.5K miles) "B" spring next to a new "A" spring. The "A" has been on another rig also, that owner wanted two "B" springs to have a more level "look" I wanted the high rear end for loading up. this is what DLS is talking about. the A and B thing is for rigs not imported to the US. Does not apply to our set up and un-loaded weight distribution. USA rigs probably should have either two "B" or two "A" springs, the A springs will be about a inch higher in lift than the B springs. I've got ARB bullbar and a 8274 on the front so it may have settled more than if without..again I like the idea of the rear being high unloaded..when I add the rear tire/jerry can rack and load her up I bet it will level out

Hope this helps

Having lived in Seattle for the last few years until returning to Sandy Eggroll, I spent much time at ARB. Super nice guys... Just completeing a FJ to HJ-60 transplant just prior to moving, I went thru a few springs during my OME upgrade. For some strange reason the produce "A" and "B" springs "+" and "-" springs...and they wish they would just get one type either the +/- or A/B. I can tell you that the +/- if you get them means (- = just under spec) (+ = just over spec) and there is even a (0 = at spec) the dirrerence is nill to you and me.... in short....put + on drivers side. as with the "A"
And as a side note they make reg, heavy and extra heavy duty (recomend the EHD fronts for the HJs)

so is "decomend" a spelling error or are you trying to say that you "de" "recommend" them?
 
Thanks

Thanks...I am glad I am better with a wrench than a keyboard... It was good meeting you in your office last summer.....we'll have to go back again soon.

Thx C
 
So, what about all the rigs that are set up with the A and B springs already. I got mine from cruiseroutfitters, and that's the way the 'kit' comes. I haven't noticed any lean, then again, I didn't have any lean stock.

If having A and B springs is wrong on USA models, is someone gonna step up and swap out all the setups already out there?
 
phoenixrider, you do realize if you swap to two A's or B's now you will have a lean, right? Why would you want to change springs that are giving you a level truck for some that will create lean? :confused:

OME does not make a "KIT". Each dealer assembles the individual parts as a package. There is another thread going that has some great info from Kurt in it.

In a nut shell, the hundred if not thousands of OME kit that have been put on USA version 60 have no problems. A very small percentage have a lean. Nobody knows why. Most everybody has really good luck installing the A spring on the drivers side.

Everybody who has experienced this FJ60 OME lean is a member of IH8MUD.

I installed my OME on my 60 and have no lean. I went with the CS400.


I personally thing it has to do with the spring rate and labeling at the factory. I think a few CS300 were labeled CS400 regardless of the A or B.
 
Say What?

Here's some questions I have. If anyone has answers, I'd appreciate you jumping in.

Is it typical for cars and trucks to have different springs from one side to the other, or is this uniquely a 60 thing? I always assumed that a left and right spring on a car or truck were identical.

If the dealers are putting the "kits" together, can one request identical left and right springs from the dealer?

Are factory shocks still usable with an OME lift? Or should one buy new shocks?

Not specifc to a 60 to my knowledge.

On all the vehicle I have worked on they are the same left to right.

You can order what ever combination you want from Kurt at Cruiser Outfitters. I cannot speak for the other OME dealers. If you want two CS400 A's you can order it that way.

I believe it is recommended to replace the shocks with longer ones.
You do not want your shock to be what limits you suspension travel. If they are constantly pulled beyond thier recommended travel they will break.
 
Thanks

Thanks, D'Animal.

I'm going OME from Kurt. I'll wrench it myself and see how it turns out.

Got it all covered, but might add that if you do the MAF u-bolt flip kit you will want stock length front shocks...
Stay away from MAF.
Go to Kurt at Cruiza Outfittas. :grinpimp: He'll get you da hookup fo' yo' fix!
 
Cruiser Outfitters for OME - no question about it

There is no question that I am buying my kit from Kurt at Cruiser Outfitters. That guy has so many positive testimonials, it is amazing. I hope my own customers feel similarly about me!

I will digress a bit here and put in a plug for Cruiser Dan as well. I ordered some parts from him today. There is a man that knows Cruisers!

:banana:
 
I couldn't decide which "A and B" spring thread to bring back from the dead, so high desert is the lucky one. How are the kits coming now?? Is there a definitive go with two A's or B's? ARB's website says in the application PDF:

"North American models do not lean so the same spring should be used on both driver and passenger sides, choose CS017RA for a 3”
lif t or choose CS017RB for a 2” lift"

I ask because I pieced mine together from 4wheelparts, and its starting to trickle in. I would have gone with a long time forum supporter, but being in Hawaii shipping made that cost prohibitive. I ended up getting two "b's". Is anyone able to put my mind at ease with this crap? It takes a month to get this stuff, need to put in the order now if a switcharoo is necessary.
 
If you're going to be carrying loads or have a rear bumper; I would definitely swap out for two A springs. Good that you already have an identical set though.
