These trucks are not designed for drag racing. 4.10 rear gears would put more torque to the rear axle but if the tires lack the traction to turn that into acceleration it's not going to buy you anything anyway. Chevy understands how different rear end ratio's are not all that important anymore, now that we have 6 speed transmissions. So, they save their customers all the confusion. Ford decides for you with their F450 and F350 dually. The idea is this: You are towing your trailer down the highway at 60 mph and hit a hill; say the hill is that steep that your engine only has enough power to pull it at 50 mph. The truck will slow down. If at 50 mph your engine can run at the rpm where it makes peak HP you had the perfect gears for that hill. Next hill maybe a little different gear ratio would have been better.

Absoloutly, the low speed stuff is where the gearing really shine. At higher speeds with higher gear the trans will just downshift. If a downshift isn't required the truck with the lowest gearing will have the easiest time moving the load.
