Not sure if I should post this in here or with the 15-18 guys...

Anywho, what little reading that I have done on them indicates both truck use the same suspension. Many (if not all of) of the leveling blocks interchange.

aand then there is Auto Spring with their rear add-a-leaf kits that has 2 different part numbers for these trucks. AAL1501 and AAL1502

Anyone know why this is? Are both AAL kits interchangeable?

I know someone selling an AAL1502 kit and just wondering if it will fit my '12.

Thanks
