WHY is a 1 ton spring perch width different? Just the hangers?

    We all know a 1 ton rear end has a different pad spacing than a 1/2 or 3/4T, is it just due to the spring hangers being different spacing, or is the whole rear end tapered in?

    The hangers are different. They're more or less straight down instead of angled outward. Having the hangers tighter in to the frame allowed GM to use the same chassis on the assembly line for both SRW and DRW applications.

    To add to John's point the hangers allowed the 1 TON Cab Chassis to use the super narrow dually axle that would allow the fitment of several aftermarket utility boxes - the Cab Chassis were available in SRW / narrow dually and wide dually versions.The narrow sring hangers amde the same package more versital and less part changes on the 1 TON's .
