nbs rear swap into an obs 1997 tahoe

[cjcb1100]

Did new rear axle have the correct gear ratio, or did you have to change ring and pinion? Did you install larger front Differential?

both happened to be 3.73 would like to swap in some 411 not sure if the half ton front diff will fit a 411 i want to find a 1 ton frame and put all these parts on it bonus would be the tougher front diff

5.13 is the biggest numerical gear you can fit in a 10 bolt.

Yeah, I like that idea for an upgrade, my 95 K2500 has 3.73 also.

Looks nice!!! Is the new set up much wider than the original axle and rims?

On my truck i didn't measure the width i know the yukon and suburban both have a narrower rear but on a 3/4 to 3/4 i think their about the same fills the wheel well the same with the nbs wheels

I am just finishing up doing this swap with out a wielder. It takes a lot of planning and measuring.
But I have done it.
I went with a 2005 Tahoe rear
