Newest Rear Or what's an upgrade for GMT400 K1500

[RamahX]

Will a NBS rear 3.73 fit one of ours? i.e. would say a 2005 fit my 94 K1500.

Or... What upgrade fits i.e. would a K2500 rear fit (same ratio).

A 14 bolt would be your best upgrade.

Some K1500s came with SF 14 bolt rears

Either a K1500 with the F44 RPO code or a 2500 6 lug will have a 14B that you are looking for

im actually in the process of doing the 14 bold SF swap from a 10 bolt very easy and everything bolts rite up. all you need are u-bolts because the axle is wider and a u-joint that you can get a Napa for 10$. i actually have a extra 14 bolt SF 6 lug 3:73, just getting it to you would be difficult

the newer axles do not work, or atleast you would have to move the spring perches inward like 1-1/2 inches to fit....

What's the RPO for the 14bsf with 6 lugs? And is it the same G80 locker?

On the half ton your looking for an F44 RPO code. The 14 bolts and 10 bolts have a different G80 I think. The 14 bolt is much stronger.
