Gear ratio help needed
I've got a High Pinion Dana 30 being rebuilt (with WJ Knuckles) that will replace my LP. I'm also swapping out the rear diff (Chry 8.25) for a Dana 44 from ECGS. I'm undecided on whether I want to run 33x12.5x15 or 35x12.5x15. I'm leaning on the 35 side. So that leaves me with a big question mark, what gear ratio to go with, 4.56 or 4.88? It'll be a daily driver and a weekend trailer. Nothing too crazy. Freeway speed, 75-80mph. I would value your input.
Thank you
