Has anyone noticed whether your rear OME springs are the same exact height? I installed mine this weekend and noticed one about 1/2" taller than the other. Both have the same model number and I cross checked them with the OME manufacturer's application list to make sure they were the correct ones for the WK, but one has an 'A' on the sticker and the other a 'B' so I wasn't sure if they were a right and left. I installed the taller one on the driver side in case it's meant to compensate for the driver's weight...I'll have to let them settle to see if they even out. I wasn't sure if I have a slight taller spring due to manufacturing error or if they are meant to be that way...
Ok, so I just found this online at ARB (I guess I made the logically correct choice):
As a general rule, the A springs have a higher free height than the B coils. This is to allow the fitter to compensate for driver weight, aftermarket accessories, vehicle weight distribution, and chassis twist. We suggest taking measurements at each corner before fitting the new suspension components. This will allow for more accurate A/B fitment.
In vehicles with front and rear A/B springs, most of these vehicles will be happiest with an A coil fitted to the front, driver corner and the opposite rear, passenger corner. In vehicles with only rear A/B springs, most will end up with the A spring on the rear, driver corner.
It must be understood that due to the A/B variation, the first spring selection may result in the vehicle to be unlevel. If this is the case, swapping spring locations is necessary before trying other trimming methods."
