Rear end gearing
Since my chasis was built in 1984, 55 MPH speed limit, I top out at 72. I'm considering a rear end gear change to help my top end and mpg.
400 cummins with a 9 speed eaton...pulls like a banshee and with my 15K of trailer and toys, I can motor past people uphill...till I run out of gear at 2100 rpm / 70-72 mph.
Thoughts? Am I on the right track? Anyone have any gear change experience?
