Anybody ever seen or done a Avalanche dually?
 

i've always wondered why no one has converted a 2500 Avalanche to a dually. 4 doors, big block short wheel base for easy turning. I remember Chevy made a 4 door short bed dually in 2000 or so that was marketed towards people who pull fifth wheels and campers. I have sen the adapters to convert the 3/4 axles to dually hubs but never seen dually fenders for a Avalanche.

The Avalanche is on the Suburban Frame, not the pickup. Putting dually fenders on one woud be tough and resale tougher.

Go ahead and give it a shot!!!!

I owned one, but never considered it. The problem with the Avalanches is their wheel openings are small. That restricts your wheel/tire size choices unless you lift.
Upgrading an Avalanche to a dually is never going to give you the stability you are looking for. I LOVED my Avalanche, but the frame just isn't that of the HD line of trucks. I could see my frame flexing aft of the rear axles when I was towing within factory specs. That's when it was time for me to sell it; and I bought a dually.
Now I have an F350 Superduty & a 2500HD Chevrolet.

My 2003 2500HD Chevrolet long bed/extended cab,
4x4, 4.10 gears, 8.1L gas & Allison 5 speed automatic; pretty much stock on 33" tall tires.
My 2002 2500 Avlanche was:
4x4, 4.10 gears, 8.1L gas & M32 4 speed automatic; lots of bolt-ons including 32" tall/wider tires (see mods below), exhaust, tuner, FIPK, and a few others.

My 2500HD truck tows 12K lbs. MUCH better than my Avalanche EVER did.

I know we can't all afford to have multiple vehicles, but I would suggest dumping your 2500 AV and getting an older HD/Superduty truck for towing only, and picking up a 1500 Avalanche for a daily driver.

Found this pic online, but looks to be a photoshop. To my knowledge, all of the 2500 Avalanches had cladding.

The best bang for your buck to improve towing stability on the 2500 Avalanche (or 2500 Suburban):

2" rear wheel spacers
Ditch the factory 6.5" wide pizza cutter wheels and go to 8" or 9" wide wheels & wider tires.
I was running 17x8 Helo wheels and 265 series E-rated tires on my best setup.
I also had rear airbags on my AV, but in hindsight they may have been actually contributing to my frame sag issue.

Arrow craft out of mich would be the place to ck out .

No I don't own one. I have a 1996 C3500 extended cab dually. I was just wondering if anyone had converted one. I remember 20 years ago that the Suburban dually's were a cool conversion and wondered why no one did something similar to the Avalanche or even the newer Suburbans

Older model Sub but gives the general idea. Like said already the 2500 Av has the cladding which would be problematic. I have actually thought about buying a 2500 Av and swapping out my non clad Av body of my 1500 so I would end up with a 2500 with no cladding.
