NBS Front Brake Swap for OBS Trucks

[great white]

Ah, this seems to indicate new shafts are needed for 2500/3500:

Still, do-able if you want to spend the cash....

I seem to remember the gents who were putting 2500 shafts into 1500's were machining down to the outside diameter of the outer joint to get it to fit...

I would like to do this and find out definitively, but its going to be fall before I'm around my truck again.


Edit: Awesome find Great White. That second link has a great write up. Now its got me thinking about swapping out the rear end too.

The only thing I don't like is the fact that the hub carrier is so much thinner than the OBS. For me it probably won't be an issue, as I'm not going to beat on it and the addition of the larger brakes more than compensate for this.

off topic but whats the difference between 1500 and 2500/3500 shafts?

If you have a 2wd just use NBS 2wd spindles, might be different size BJs though.

If you have a 2500/3500 just use NBS 2500/3500 spindles and tell us if the CVs fit. =)

but NBS 2wd is 6 lug, i like my 5 lug wheels.

99+ 2wd and 4wd knuckles are the same, correct?

 

[Half Assed]

this is awesome. So 2010 14" rotors will work also? I have 18" wheels

Would this mod work for non abs 1500 trucks? I would assume so but is there a confirmation?

Awesome, nice write up and pics!!

Great writeup! Any body do this to a 2wd yet? I would even keep the 6 lug, as wheels in 6 lug are easier to find, if the offset doesn't get way out of line because of this.
