Are 4.30's gears even produced for the rear? I know 4.56 are. I think you would have more success with a 4.10 gear. Is the truck auto or manual? I ask cause you sound like me, want more grunt off the line...

cause running 4.56 with 26" tires i was crossing at 6400 are better some times

30" tall tires were just right but used them up and spray a 70 shot and was hitting 6700 about 150 to 200 feet from the end
