Rear axle Q
 

A question about dually axles. I know in the square body tracks the pickup and the C&C rear are different widths,is it the same with the newer trucks?

Yup, but dunno what the widths are....

There are three different Chassis Cab rear axle widths. One is within millimeters of a dual rear wheel pickup, the other two are narrower. One is 8" narrower (w/o RPO: GTY), the other 6-1/8" narrower. The 6-1/8" narrower one is the 10-lug rear axle found in the 3500HD chassis cab trucks.

I am looking at a table of track width measurements for DRW trucks. The track widths are: ~73" for a regular DRW pickup and one type of C-C, ~65" for the narrow C-C, and ~66.75" for a 3500HD. That is measured center of dual-center of dual.
