What is the gear ratio of Ram 1500?
What is the gear ratio of Ram 1500?
Ram has a standard axle ratio of 3.21 on 2X4 trucks and 3.55 on 4X4 trucks and trucks with the diesel engine. However buyers can choose different axle ratios for their Ram 1500, including a 3.92 axle ratio.
Which is the correct gear ratio for a truck?
But that gear ratio would most commonly be referred to as “3.55” or simply “three fifty-five.” The key to understanding gear ratios is to remember that, as the numerical ratio goes up, towing capacity increases but fuel economy goes down.
What’s the difference between 3.55 and 3.73 Axle ratios?
Gas Mileage A numerically high axle ratio means your drive shaft makes more revolutions and therefore the engine works harder and uses more gas. According to Truck Digest, going from a 3.55 axle ratio to a 3.73 will cost you a quarter mile per gallon in the long run. This manifests itself on long hauls.
What is the rear axle ratio in trucks?
The term refers to the gears in the truck’s differential, which is a mechanical device that links the rear axle to the driveshaft and then the engine. Technically, the number should be expressed as a ratio, such as 3.55:1, meaning the drive shaft turns 3.55 times for each turn of a wheel.
What should the gear ratio be at 65 mph?
These calculations are assuming a manual transmission at 65 MPH with a gear ratio of 1:1. If you drive an automatic your RPMs will be slightly higher, and if you have overdrive your RPMs will be slightly lower. You have no items to compare.
