Hi all im new to this site nice to meet you all!
So i am doing a powertrain upgrade on a customers bus, we are looking at swapping out the o.e rockwell H170 rear to an H172 for more gearing options/availability. The two ways I'm hoping to get lucky are :
1) there are a bunch of H172 rears available locally but have too tall of a gear for our highway goals (they are 5.80ish -6.87 ) . is there anyone that has a 4.11-4.56 gear set they'd be willing to trade for the taller ratio?
2) Could trade rears straight up (possibly negotiable) the H170 we have now has 6.83 gears in it now. Its a face loader, hydraulic brakes.
These old axles have no support for gearing options in our desired 4.11-4.56 window so this is sorta of a hail mary lol!
Any knowledgeable folks that know of ring & pinion interchange options would also be a huge help!
Thanks in advance
