14 bolt shaft lengths, SRW truck

redneckengineered · Aug 9, 2017

Looking for the shaft lengths on ribbed housing 2nd gen 14 bolts (~88-2000ish), specifically from a SRW truck. No dully's, vans, or C&C they have been known to have funky widths...

I'm curious if the 2nd gen SRW truck 14 bolts are the same as the first gen which are 31 5/8 and 37 5/8 give or take an 1/8th.

Thanks

I just took the shafts out of a 1992 14 bolt and they were the same as the older ones

Not sure if these measurements came from "big block" style ribbed housings but according to 2 different ebay f/s ads I just looked at one guy has a 14b ff from a 95 2500 p/u showing a measurement of 32.25". Another guy has a long side from a 99 k2500 with measurements listed as 36.5". So, as far as these axles go, I'd say a gen 1 short side would probably work in a 2nd gen axle. Not sure about a gen 1 long side. It would need to have at least 1.125" of additional spline length engagement available.

Were they for sure SRW trucks because that is strange.
