I have a 2000 club cab slt 4x4 with the 4.7, nv3500 3.55 open diff, currently have 31x10.5 15 hankook atm. I am going to have my shop install an Auburn Ls. I am doing this for better traction in winter and I drive quite a bit on forest roads, driveable trails, and often times find myself going on at trails that are badly mangled. I am wondering if I should have him put in 3.92 instead of the current stock 3.55, the nv3500 seems to take forever to get from 0-60, and 1st gear is hardly even practical. I was wondering from someone who had the same set up what your experience is. Thank you

 

I have the 4.7, NV3500, and 3.92's in my 2000 club cab.

It'll wake it up. The 4.7 likes to rev!

 

Thanks for replying. Is yours the 9.25 axle? Limited slip?

 

Yes, the 9.25 with limited slip.
