Re: Post pics. Lets see how many 60-66 4x4 are out there.
The Suburban is mine and yes it is real. You don't think I would leave it looking like this if slid something newer under it and/or photo shopped it. HA. The crew cab is one that I almost bought last summer.

Re: Post pics. Lets see how many 60-66 4x4 are out there.
question; did these early 60-66 4x4 transfer cases have a low gear on top of the allready "granny gear" in the gear box?
are they the same in chevy and/or GMC? |

Yes they had a low range. With the low gear in the 4 spd trans and the 1.96 to 1 low range it approximately doubled the low gear ratio. The Rockwell transfer case was used in the Chevy and GMC 4x4's from 1960 to 1966 in the divorced application that you have.

Re: Post pics. Lets see how many 60-66 4x4 are out there.
Your welcome. The SM420 transmission has one of the lowest first gears of a light truck 4 speed, close to 7.0 to 1. So if you double that plus multiply it by your axle ratio ye get your crawl ratio. 7x2x3.73=52.22 to 1. That is rounded up except the axle ratio which should be 3.73 for a half ton unless it was ordered with something else.
Anything over 40 to 1 is considered pretty good. Keep in mind the new NP 241 aluminum t-cases have a 2.72 to 1 reduction ratio. So a NP 241 behind your SM420 would net you a 71 to 1 crawl ratio! |

Re: Post pics. Lets see how many 60-66 4x4 are out there.
Can't speak to the later years, but the 60 and 61 K10's had a 3.90 rear ratio (3.92 at the front-they can't be numerically the same)
So 7x2x3.90 is 54.60 And the K-20's had a 4.56 rear So 7x2x4.56 is 63.84 |

Re: Post pics. Lets see how many 60-66 4x4 are out there.
^ Correct. I forgot that the 1/2 ton gear ratio changed in 1963 when they started installing 12 bolt rear axles. So if you had a corporate HO 33 with a dropout center section in the rear axle it was probably 3.90 and a 12 bolt would have been 3.73.
