2015 RAM 3500 DRW to SRW conversion - what backspace is needed?

I’m pretty sure on a newer Ram the axle length is negligibly larger on a DRW. We are talking millimeters not inches.

I want to say it’s less than an inch difference. Which when you consider it’s centered the same you’re looking at less than half an inch on each side.

If so, Id run the same wheel on all 4 corners.

thats what I've read on an AEV forum also. someone said it was a 1/2 inch difference in length in total.

If it is ½” difference, then you’re looking at a quarter inch side to side. That’s like 7mm.

Run the same wheel on all 4 corners and save yourself money and headache.

I think it is more around a few inches difference if you are talking the standard Ram dually. It's closer on the cab and chassis with the front hub spacer removed. The rear axle lengths are different from the cab and chassis as compared to the regular dually pickup
