The rear end is a Ford 9" with 3.50 gears. With p225/75R15s I run about 68 mph @ 2000 rpm. I got 20 mpg running an errand to North Platte and back. I really like this combination so far. I put a clutch assembly from a 1.5 ton truck in so if I would need to tow anything the clutch would take it. | | |
