Hi all,
In an effort to determine whether to add air lift for an improved ride to my SO 3500 CCSB SRW order, I set out to determine the differences between the springs both visually and by part number. Below is a table of the part numbers for several configurations (including a 2500). I obtained these by visiting several dealership and taking photos and/or recording the part numbers on the springs. Below the table are photos of two 3500 gas CCLB SRW trucks, one with air suspension and one without. Here are my observations:
3500 without air suspension: four leafs total - two full leafs and one ¾ length leaf strapped together, ends of the fourth leaf are separated from the three leaf pack with bumpers at both ends, three spacers between the spring pack & axle. Three leafs are the same thickness, fourth bottom leaf is thicker.
3500 with air suspension: three full leafs and one front ½ leaf - two full leafs strapped together, ends of third leaf separated from two leaf pack with bumpers at both ends, end of front ½ leaf even with end of 3rd leaf, one spacer between spring pack & axle. ½ leaf is thickest leaf of either spring pack, third leaf thicker than two that are strapped, but thinner than front ½ leaf.
It is interesting that the air suspension front springs part numbers are different from those without air suspension.
At this point I am leaning towards adding the air suspension. If down the road the system becomes problematic or fails I'll replace with the non air suspension spring pack or something after market.
