I put a wanted ad on C.L. for a donor truck for my Crew cab project. Got a call from a guy with a 92 W350 that he said someone else came and looked at but said they couldn't use it because it was a cab and chassis W350 so the rear axle is 8" narrower than a standard DRW truck... Anyone know if there is any truth to this?? I've heard the DRW axle is narrower than a SRW axle but not a C/C narrower than a DRW truck......

 

The cab and chassis rear is narrower then a dually with a factory bed.

 

ok.. Is the frame the same or is it just the axle width?? will that axle/springs bolt up to my 85 Crew cab frame??

 

Frame width is the same. Springs,,,, The only difference in the spring packs, other then number of leafs, that I know of is the bushing bolt size in the spring eyes. I replaced my rear spring hangers on my 93 with some earlier ones and I had to drill the hangers out to accept the bigger bolts.

 

Ok.. I'm going to flatbed anyways so maybe this will work out!!

 

Make sure you double check me. Somebody else agree with me??

 

I agree with you.

 

The cab and chassis axle is two inches wider than the single axle. If you are building a custom flat bed, you can make it the right width. If you put it under an eight foot wide bed, it would look lost.

 

So I would be looking at a cab-width flatbed? I was hoping to purchase one since the one on my last truck was home made and I was never happy with it, but that truck was SRW.

 

Manufactured flatbeds come in various widths as ordered. The single wheel axle is the most narrow, the cab/chassis model is 2" wider than the srw axle to accomodate the dually rims for spring clearance. The pickup box dually is 5 inches wider than the single wheel axle and is the widest. The dually pickup axle would make for a pretty wide flatbed by the time you covered the outside tire. The c/c axle will work well with flatbeds as they are designed to span the outside tires on c/c trucks. Not in disagreement with anyone, just trying to clarify based on my experiences.

 

a 8 ft w bed will be ok for a dulley axle ,if you are looking for a axle cube vans have wide axles and are usealy cheap.
