OBS to nbs rear disk?

[atyates]

Can it easily be done? Or should I just do an axle swap with a nbs to get the rear disk? Thanks

i can't speak for the 4x4 guys... but the 2wd guys that do this usually buy aftermarket kits. I know this isn't much help. i'd be interested in knowing which route you take though... the NBS rears HAVE to be stronger than the OBS rears.

(on a 2wd.. but says a 4x4 rear would be easier.. might check it out)

this is the aftermarket kit i will be using.. http://www.friendlychopshop.com/parts.html

i'm not sure if these will work on the 4x4 rear.. you might contact them and ask. they're a reputable shop in Tennessee.. they might modify a set for ya if need be.

edit.. just remembered you're six lug.. these are 5

The Little Shop kit is awesome you can piece together a kit using all OE parts. 6 lug front rotors from a k1500 calipers off of a 85 olds toranado/caddi Ive seen the caliper brackets on speedway motors and the lines you would be able to find anywhere. And the reason why i know all this is because my truck when i bought it had a first gen SSBC kit on it and over the years Ive had to replace a few things LOL

i'm gonna invest in the little shop's kit.. in the spring. i have more important things to address right now. As interchangeable as GM stuff is, it shouldn't be too bad of a job to do rear discs on a 4x4 obs.

Affordable 14-Bolt Disc Brake Conversion
If you own an older-style GM Corporate 14-bolt rear axle, you probably have drum brakes—which are less desirable for trail use. However, thanks to the innovators at Right Gear and Axle, any old-school 14-bolt rearend can be easily upgraded to disc brakes using late-model OEM 14-bolt parts found on the rearend of 2002-and-later Chevy trucks. Comprised of two billet steel adapter flanges and mounting hardware, this product offers an affordable and effective way to improve brake performance while also adding a functional e-brake. It’s manufactured right here in the U.S., and as the photo illustrates, the adapter flanges simply bolt to your existing end flanges with no cutting, welding or custom fabrication required.

That seems to indicate you need an adapter to bolt the newer AAM 10.5/11.5 factory disc brakes to the older GM 10.5 axles.

Also, keep in mind: somewhere around 2011 GM changed the 8 lug pattern so those rotors will not slip on over the older hubs...
