To know which ones you need, you need to know the [sales codes] for your build.
SDA = Normal Duty Suspension
SDM = Export Tuned Suspension
+ ZCV = Spring - Left Rear, Or ZRV = Spring - Right Rear
+ ZCW = Spring - Left Rear, Or ZRW = Spring - Right Rear
+ ZCT = Spring - Left Rear, Or ZRT = Spring - Right Rear
+ ZCU =Spring - Left Rear, Or ZRU = Spring - Right Rear
+ ZCX = Spring - Left Rear, Or ZRX = Spring - Right Rear
+ ZCY = Spring - Left Rear, Or ZRY = Spring - Right Rear
As you can see each spring can be used in either location.
For proper ride height you need to know which one to use where,
for your particular build.
IE;
ZCV = My Left Rear, But ZRU = My Right Rear.
Do not assume your build is the same as mine...Not all OEM springs are created equal, in length, or rate, or both. Which is why a lot of folks that lift with = rear springs, find one corner that sits just a hair lower than the other side.
If you go to a dealer with your VIN, mileage, and prof of ownership, they can print out an "Options Report"(build sheet) for your rig. Some may charge a small fee for this...
One last thing. The Options Report may have an extra letter by the code. So in my case ZRUP is really ZRU and ZCVP is really ZCV. Not sure why they do this.
Hope this sheds a little light on things.
