how much wider is a dually rear

[melmount]

Does anyone know how much wider the dually rear end is then a srw?
I have been told 1.5 inches a side. That would be 3 inches wider total? Wondering if anyone has actually measured or knows for a fact. I am making mine a srw.
If its 3 inches total I can use 05-07 wheels and get a normal stance due to the 1-7/8 more back spacing. I need an actual factual number.
thx for the help

Much wider. The fenders are about 4" on each side.

what do you mean fenders? Maybe it was the way i asked.I am only concerned about the rear axell, not fender width. The fenders are coming off.

The 99-04 DRW uses a Dana 80 rear end which, WMS-WMS is 67.5" wide. The 99-04 SRW uses a Sterling 10.5" rear end that has a WMS-WMS of 68.875" wide. All of our trucks, 99-04 uses some variation of the Dana 60 front axle either full Dana 60 or at least a Dana 60 housing with Dana 50 inards and it has a WMS-WMS of 69.25" wide. The outward differences come from the wheels that are used and there is a substantial step out on the DRW bed, but if all you want to do is run a SRW bed/wheel combo you would simply need the correct set of wheels to have a factory spec rear tract width. A 1.375" spacer with factory wheels will do that for you. Hope it helps.

are you saying the dually dana 80 is narrower then the 10.5? I thought it was wider?

resurrecting this thread. I am thinking of converting my 02 dually. So let me get this straight. Get a set of 1.375" spacers for the rear, pull the spacers off the front, new lugs for the front. New set of wheels...
Now for converting the bed...

I can either hunt down a srw bed or pull the dually fenders off. If I pull the fenders off, is it just a matter of patching the mounting holes and a respray? Or are the beds totally different?

only dually rears from cab and chassis are narrower. A regular dually rear is wider! I am positive. I went back and forth trying to gather info.
If you get wheels for an 05 and up truck they have 1 7/8 more back spacin g then 04 back factory stuff. You will need front 2 inch spacers after removing the large ones up front. The back needs none. Its wider.
As far as the bed just fix holes and the cut out at the bottom.
