Just thought people might want some info on the 14 bolts axles for people who are for doing axle swaps to run the big semi rims. The SRW axle can be turned into a C&C by changing out to the hubs & drums from a C&C or DRW axle, all other parts stay the same. The first design axles ( 72-88 ) have smother cast center sections & drums are pressed onto the hubs by the wheel studs. The second design axles ( 89 on ) have fins on the center section & the drums slid off the hubs. I don't know if the hubs & drums between the first & second design axles are interchangeable.

If anybody has any other info, or if I missed something post it here to educate me & others who read this posting.

Axle width measurements
SRW---67" wms to wms
DRW---72" wms to wms
C&C---63" wms to wms
