Dually SRW swap

[Wing Nut OOA]

so my brother has a 98 K3500 crewcab and i've got a 95 K2500


he wants SRW and i want a dually.

what is the easiest way to do this?


i know there are adapters for my font end but what about his front?


would it be easier to just change the whole hub?

how much of this is interchangeable.

It's hard to say, with a 95/98. Your 2500 must be an HD (8600 GVWR) to consider it. Measure and compare the components. You may luck out and have a direct swap of the control arms-out. The rear should be a no-brainer, for the most part. Steering and brake components (like the master cylinder) may or may not be an issue.

What about the beds? Are they the same size? Are you planning a swap of those, as well? Duals under a fleetside bed won't work, and singles under a dually bed looks just plain silly.

Swap trucks....

I think you can just remove the dually adapters in the front. Unbolt them, put on the single wheels and and see if the track is the same. The adapters are just bolted to the studs on the front rotor. What I am not sure is if you can bolt the adapter to the 2500 rotor.

You may want to go to something like Rock Auto and do some part # comparisons.

lol, i would love a crew cab dually but his is kind of rough.

dont get me wrong its got all the bells and whistles mine does but the engine is a 454 that is almost on its last leg.

i tried getting him to buy that fubar'd duramax engine off ebay for 2k a while back but he didnt have the money.




i'll definetely be looking into that front end spacer thing.

i wasn't aware thats all they did.


yes my truck is the 8600GV


the only down side is i dont want 4.10's

so i may make him keep his rear and i'll just get the spacers for the back.

The dually rear is actually narrower than a single wheel truck, so you would need the dually rear end. The gears on a 14bolt are not that hard to change.

[Wing Nut OOA]

dually rear ends are wider than SRW

so the inside dual tracks in the same line as the front wheel.



the kits come with a spacer to compensate for this.


its about 1.5 inch thick.

Hi
Daully rear ends trac both wider and narrower than the srw diffs.The wide ones are for trucks with pickup boxs,and the narrow ones are for cab and chassis.I happen to have both sitting in my parts pile.You can convert a srw diff to dauls by changing the backing plates and drums fror a daully diff.The daul wheels wouln't go over the srw drums.But if you change a pickup daully rear diff to srw the trac will be way off and will look odd.And if you change a srw to daulls you will have to cut out your wheel wells in a pickup box.I was going to put dauls on a srw diff on one of my trucks.Was going to cut the wheel wells out of the box,then it wouldn't be as wide as the dually trucks are,but i wouldn't be able to haul anything that was 4ft wide between the wheels,eg a camper.I think the look would be nice the duals would stick out a little,a flare would take care of that.
Have fun

so all else aside with the rear.

i need some suggestions for the front or this isnt going to happen.

As I mentioned earlier, measure and compare front end components and the frame mounting points. If they match up, replace the fronts from the control arms-out, which will likely also include the torsion bars. Only 4 bolts, and the correct hub and brake components go where they need to.

why replace a arms and all? act like you are installing new rotors and wheel bearings strip each truck down one side at a time and switch them over only real difference up front is the dually adapter on the rotors (which you may be able to unbolt cant remember).. rears its really as easy as measuring drum to drum on both trucks and seeing how close they are.. I know of few guys running the narrow DRW axle with duals on a truck with normal bed... just use a small fender flare to cover the tires (since they dont stick out as far as normal duals)

It's been a few years, but I remember looking at my friends '95 K-3500, and the front adaptors looked like they just bolt on over the hub assmby. As in, by the looks of it in my memory, you could in theory, un bolt the adaptor for duallys, and bolt on a reg single wheel rim, with the correct lug nuts.

My guess is you could swap adaptors on the front, swap drums and backing plates on the rear, keep your own front rotors and calipers, and front and rear gears, and be good to go...

But haveing both trucks side by side, on jack stands with the tires/rims off, and a tape measure and note pad in your hand, and your thinking cap on, you'd be able to tell the diffrences easy enough. Just compair one to the other very closely.

Good luck... Duallys are nice... I've got a few... my chevy is a wanna be, still has single wheels on front, but I've run dual rears for a few years when it was a work truck.
