single and dually

[crashz71]

hello can anyone tell me what the track width is for a dually and a single wheel truck with the aam rear end.Or are the rears the same width.

I know theres at least 2 diferent rear widths. I just cant seem to find them.

 

[Chevmeister]

Ok the two I can confirm are DRW and cab chassis DRW are different but i cant find measurements. I know the brakes and hubs on the DRW vs SRW are diferent, but I cant find data on the measurements.

DRW is 2" per side wider than SRW. I can't remember what the mounting surface to mounting surface distance is though.

Mounting points are the same, the dually axle is just wider to give clearance on the leaf springs. You are correct on the 2" per side.

Well the spring perches are the same distance apart, but they are different heights off the tube (2500HD comparing to 3500 DRW GMT800's) so it will affect the rear height of the truck.
