Message: [QUOTE="stuckinmud, post: 373421, member: 2759"] I have 4.30's on 35's. When I had the 6.0l it would turn about 2150 @ 70 mph with a corrected spedo. Now with the dodge trans and 2 less cylinders its slightly different lol. When I did the math I figured it was close to running the oem tires at about a 3.90 ratio. This was in the middle of the factory 3.73 and the 4.10 option. Keep in mind in 05 4.30 became the tow boss option but the tire size became slightly taller so it is sort of the equiv to a 4.10 gear on a 99-04 truck w/ stock tires. It is easier to get it moving when towing/ racing and really not all that bad on the highway. [/QUOTE]
