C&C to dually

Hi guys, I just got a 94 cab and chassis truck (reg cab) on the cheap, wanting to put a dually pickup rearend and dually bed on it, my question is, is it bolt in simple? I've heard the wheelbases are different for the "short" cab and chassis and the 8' bed pickups so the wheel wells may not line up and the spring pad widths are different? I know a lot of guys go the opposite direction to fit the wide semis under, but I plan on running stock 16s.

Thanks,
Rob

If it's a regular C3500 (not 3500HD) cab & chassis, the frame from cab-back is totally different, C&C uses a straight frame setup measuring 34" center to center to make it easier for the aftermarket to design utility beds, wrecker beds, shit like that for them. It also is dead-flat once the kickup behind the cab. You put a dually bed on there you'll have inner tire interference with the bed sides plus all kinds of fit issue due to the significant frame difference. Sure you can overcome it, just gonna be work.

Be easier to see if you just look at yours but maybe this pic will give you an idea of what I mean on the frame profile. See how it is flat across the top:



As far as whether the bed will fit wheelbase-wise, you have to determine what wheelbase you have. A normal dually regular cab has a 131.5" wheelbase. C3500 cab & chassis are offered in both 131.5" and 135.5" along with longer versions, too. Obviously anything other than the 131.5" will give you trouble. If the SPID label in the glovebox is still there & legible, it will have the wheelbase printed on it. Otherwise, you can try measuring from dead center of the axle, to behind the cab. The 131.5" wheelbase will be about 56", the 135.5" of course will be 60". That's an industry standard for the aftermarket beds, known as a "60 inch cab to axle"

Thanks for all that info, I really enjoyed your 3500HD build. This is the 135.5 wheelbase truck, I got this thing dirt cheap and had planned to put a dually bed and wide dually rear end under it and slam it, there are zero slammed regular cabs around my area. However, looks like I'm up against having 4" sectioned from the frame and making spacers for the bed to sit on, in addition to purchasing a bed and dana rear end and lowering kit. I may be better off holding out for a different truck.


Thanks again-

No prob...

I keep thinking of what kind of bed could be made for a C&C that wouldn't look gay on a driver vs. work truck. Whatever it is, it'd have to be a full fendered type like a Western Hauler, wrecker bed, something like that.

Thanks for the props on the HD build, I hated to sell that truck but it went to a great home. My plans for the next one include an idea or two from the new owner of that truck, let's just say if I end up doing that, I'll have a kickass HD that is gonna trip out people, totally blindside them...and still be a work truck.
