    1991 Chevy R/V3500 Crew Cab Build

    The donor truck my Cummins came from had some cheap Ebay electric fans already installed, the truck ran good and didn't get hot so I left them when I did the swap. I have always though that having something with a shroud would be better so with everything apart on the front end I decided to make...

    1991 Chevy R/V3500 Crew Cab Build

    I have gotten behind with my updates but here is a quick rundown. Got the caster set, the axle centered up, tacked up the panhard bar and got some cycling done. Over the 4th of July weekend I got the Cummins installed back in and built a transmission crossmember, then over the last few weeks I...

    1991 Chevy R/V3500 Crew Cab Build

    This box came on a M1031, I am not sure if they all had them or not. There is also two versions of this box, mine has the shorter front boxes, another version has front boxes that are even with the bottom of the cab (wish mine was that way..)

    1991 Chevy R/V3500 Crew Cab Build

    So I have a few updates, the parts gathering for the suspension is 90% complete! I also almost have the drivetrain/driveline worked out, I ended up going with a Borgwarner 4401 transfer case. This gave me a driverside drop and fixed outputs on front and rear, I did however need to swap out the...

    Another, another which wheel. MRAP on a 550?

    Actually I got really lucky! I found a guy on Craigslist that had 5 MRAP wheels, with hardware and the F550 adapers and I got them for a pretty good price! Good looking truck! I wish I didn't need this much lift but it is what it is... I am at about 6-7" of lift and a cab height around 78".

    Another, another which wheel. MRAP on a 550?

    Not sure if it helps anyone but my 2008 F550 front axle is 84" wide from wms to wms. I have a set of MRAP wheels with the WCR adapters and some 395 Goodyear MVT's. With the adapter behind the MRAP wheel flange the overall setup is not outrageously wide. The front is somewhere in the 88" to 90"...

    Then I started to mess with the front, I pulled GM D60 and manhandled the Super60 under the truck. Didn't have a ton of time but I was able to get the axle pretty well square under the frame and the axle center line about where I want it. I am trying to sell some parts I have taken off to help...

    1991 Chevy R/V3500 Crew Cab Build

    Its been a little while but I have been making slow progress with the axle swap. I got started with mocking up the rear Spicer 110, one thing I can say is that the Spicer is considerably bigger than the 14bolt... The spring perches are about 1" too wide so I am going to have to move them in...

    1991 Chevy R/V3500 Crew Cab Build

    Thanks! The F550 axles are 4.88's and my current axles are 4.10's. I am planning to run some MRAP wheels with adapter plates and use my current Goodyear 395/85R20's.

    1991 Chevy R/V3500 Crew Cab Build

    So here is a little update, I have been driving the truck and enjoying it but I have had concerns that my one ton axles (mainly the brakes) were not going to hold up to the new bigger tires. Then I found a guy who was parting out a 2008 F550 and I scored the front and rear axles for a good deal...

    Spare tire carrier ideas....

    I was thinking of something similar to that, I like the idea of being able to winch down the tire! Thanks! I hated lifting's 37's and now with these, its not even a option.... I have given some thought to that but the box is aluminum so I would have to build a frame on top of the box to carry...

    Spare tire carrier ideas....

    I'm looking for some input, I am about to start building a rear bumper with a integrated tire carrier. The current idea is a swing out style carrier but the issue I am haci G is lifting and lowering the tire. I have 395/85r20 Goodyears and as you can imagine they are heavy and the back of the...

    It has been a while, here is a little update on the rig. I got a good deal on having the engine rebuilt and getting some machine work done on it. While it was off getting work done I had them do the "everyday driver" head studs, install the 3200 gov spring and add slightly larger injectors. I...

    Thanks alot Chilli! It does feel great, now i'm working out the little things and tuning the injection pump. I'm also anxious to see what kind of fuel economy improvement I get, I was only getting 6mpg with my 454 so i'm excited!
