Track width of SRW Conversion?

[dzzz]

What's the narrowest I can go on a dual to SRW conversion? Match the track of the front tires? Thanks.

You can go as narrow as the front (or even narrower), but you'd have to run two different pairs of wheels with different offsets. Since most people only want one spec wheel for all four corners, you're stuck with the rears being out a little further. (I'm speaking for a second-gen Dodge, don't know about other brands.)

In some cases the cab & chassis rear axle is narrower than the dually pick-up rear axle.

I'd have to measure it to be exact, but on my 01 3500 Ram the rear ended up a couple of inches wider than the front running the same offset wheels. I'm happy to measure it for you if you need the exact difference.

Thanks for the replies. I'm looking at a F350 SRW, or a F450 DRW and doing a SRW conversion. DRW doesn't work for snow and width/driving in track.

If I do the conversion, I will probably use 19.5 5000 lbs. wheels and an aggressive truck tire like G124. That gives me 10K lbs on the rear axle on a 13K to 15K truck.

I've given up on wider tires.
