TTB Chevy Express

[Vanguy]

Has anyone done a Dana 50 TTB conversion on a Chevy Express? Tried searching but the search kept leaving out the ttb. Thanks.

I've never seen or heard of one. Seems like its more common to go full solid axle or keep it with as many GM parts as possible by going torsion bar IFS.

[Vanguy]

Thanks. How off road worthy is the IFS all wheel factory setup? Would it be possible to fit 31’s and a modest lift without issues?

[WhitH]

The factory AWD 1500 vans can easily fit a 31 with any of the 2" lift kits you can find by poking around on the internet. Boulder Offroad sells them as one option. Good friend of mine has one with that kit and runs a 265x70x17 with no problem.


If you can find one with the G80 rear locker they are a solid performer out of the box. Its not going to be a rock crawler or anything but really good in snow, loose dirt, mud etc.

Thanks. That’s really all I’m looking for is just a little more sure-footedness when things get slippery.

[WhitH]

Should be a great option then. Hard to find a good one at a reasonable price, but they are out there if you keep looking. Make sure and check for rust as most of them have spent a fair amount of time in the NE and midwest.

Agree with WhitH. I think the IFS is enough for anything I would want to take a 9k pound van on. Might search for a Quigley conversion.

[WhitH]

Yep, there was a pretty nice 2500 Quigley cargo van for sale in Portland not too long ago. Not sure what your budget is but worth a look.

I am actually considering doing one on a GMC Rally STX 6.2 Diesel Club Wagon I picked up for $400.00. The motor was rebuilt but it has a rod knock. I have a Military version 6.2 with 38,000 miles I will be swapping in. The Military version has a higher horsepower rating. After the engine swap I may do this conversion. I have a Ford 98 F250 as the donor truck for all the 4x4 parts needed.
