I would like to be able to split the top side gears....I pull van freight in Pennsylvania and at times I pull a long hill in 9th where I'm having to back out of the throttle to keep the RPM below 1650-1700 or up to 10th and I'm lugging the engine... My question is it worth doing such a swap or just leave well enough alone. Running 11r 22.5 tires...might drop down to low pro tires next replacement...

when pulling those PA hills,.. you WANT to be at 1600-1800 rpm,.. that is the best rpm to pull with. -- that is, unless you are just trying to shorten the life of your engine for some unknown reason.

We pull through those PA hills with 80,000 lbs of nesle-water loads in and out of there all the time,.. we break every bit of 8mpg pulling that stuff through those hills, and we have a 10-speed. -- We keep the damn thing in 9'th and the rpm high most all of the time.
