The springs come with labels so you know which is A side and which is B side, but looks like yours are not there.

This is the latest from ARB and also shown in the OME FAQ:

"The way we recommend to install the coils on the 80 is with the B spring (B is taller than A for this truck) front driver and rear passenger. We recommend it this way due to the additional weight on the front driver corner. However, as long as you stagger the A and B coils the vehicle should sit level unless you have added more weight to one side than the other in aftermarket accessories"

So from what ARB is saying the taller of the two rear springs should go on the passenger side.
 
Taller spring for the front goes on driver
&
Taller spring in the rear goes driver

Correct ?
Cause PACNW96 was saying from that quote that it should be taller front driver, taller rear passenger.

Front - Taller on Driver
Rear - Taller on Passegner

That is how I read the email from ARB.

that's the way that I place mines ..
 
I did taller on driver front and rear and have about a 1/2" lean. Pretty sure if I like mention and Tapage it would sit perfect.
 
Prior to receiving the e-mail from ARB I followed the below:

"A is for Australian driver side, so in the US this should go on the passenger side and B should go on the driver side."

I installed it this way, but per the latest ARB e-mail its opposite for the rears...I would just install per ARB's e-mail with the taller rear B spring on the passenger side.
 
Anyone want to clear things up?
 
Judging by the picture in post one and the quote from OME's FAQ in the second, you have them sitting in the correct positions for the rear (taller "B" spring on the right/USPS)...this assumes your vehicle is left-hand drive.

When we just did my J coil lift. We put the springs marked with a B(taller spring) on the Driver side. Reason for this is the gas tank is on the driver side. ARB did this to compensate for uneven vehicle weight distribution.

Just reviving to confirm this. Front and rear B springs go on the DRIVER SIDE on US model trucks. I tried the rear with the B on the passenger and A on the driver side and the truck sag'd to the left by 3/4". Swapped the rears around and now it sits perfect. The truck sits perfectly level with both B springs on the driver side.
