So would a 2 speed with 6.14/8.36 ratio be what I want for the lower end power and a lil higher end then what I have now? I jus don't wanna go out and get 2 speed rear if I'm not gonna get a lil more top end speed cuz rear ends arnt cheap I did find a sweet spot that's been collecting medium duty truck since the 70s or 80s so they have quite the selection jus a lil pricey....and also been finding old farmers scraping grain trucks wit 2 speeds so I can find sum for scrap price (25cent/lb)at recycling center and that's probably where I'm gonna get one from I got a c60 front axle that I was thinking about swapping under my c50 it's heavier duty has 10bolt hub and bigger brakes being the main reason for wanting to swap cuz if I'm planning to go faster loaded probably be good idea to be able to stop faster also lol any input on this front axle swap out?
