Obs Dually conversion

[williamc51]

So I want to change my obs to a dually I'm trying to figure out the best way if I should just get a new rear axle or if I should just change up the one I have I don't really now what the diffrence is in the two but I'm guessing the axles are diffrent

THe axles are the same and I believe the wms to wms are the same as well. You'll need different front hubs, a bed or at least the fenders, and the wheels.

on a side not why do you want to change it to a dually?

The DRW axle is about 4" wider and has larger drums.

So JS your saying it would be best to just get front and rear axles from a dually or can injust use diffrent axles and put larger drums and Terry I have always wanted a crewcab obs dually but there hard to find in 4 wheel drive so I figure I would just make mine into one

[JSchuricht]

Sorry left that part out... Rear axle is wider and has larger brakes, front axle uses bolt on spacers. You should be able to get the spacers from arrowcraft. Rear axle isn't too hard, two people can swap it out in a few hours.

Ok well I'm already running two inch spacers all the way around so can I use those or are there a diffrent kind of spacer for a dually I'm lifted 6 in with 37 in tires

wms? What's that mean?

[JSchuricht]

Two inch would work for the rear, but it will be hard on the barrings. Lots of people run spacers, just not as strong as using the correct axle. The front needs much larger spacers due to the way dully wheels mount up.

[williamc51]

Ok I'll get smaller ones for the rear what size would be needed for the front

[terryknight]

I stand corrected...

The two that I mentioned built their own around here one guy is still running a srw axle with duals

WMS = wheel mounting surface
