The rear end ratio in a 1978 Chevy 1-ton truck with a granny gear 4-speed transmission typically varies based on the specific configuration and options chosen by the original owner. Common ratios for this model include 3.73, 4.10, and 4.56. To determine the exact rear end ratio for a specific truck, you may need to check the build sheet, the VIN, or inspect the rear differential for markings.
Think about changing the ratio on your differentials instead.
The "granny" gear.
Most likely, 355.
it is a powerfull first gear for either a hill,pulling a friend out or simply auling a heavy load, the other gears are just simple gears just with a slight tourque increase. thats why some people start off in 2nd rather than first.
The speed ratio formula is the ratio of the speed of the output gear to the speed of the input gear in a gear system. It is calculated as the number of teeth on the input gear divided by the number of teeth on the output gear.
All you need to do is call a Chevy dealer and give them the VIN# and asked them what the gear ratio is in your truck and they will tell you what the factory gear ratio is.
The speed ratio is typically calculated by dividing the speed of the input gear by the speed of the output gear in a gear system. This helps determine how much the output gear rotates in relation to the input gear in a given amount of time.
4.10 ratio
The gear ratio of a train, also known as its speed ratio, is the ratio of the angular velocity of the input gear to the velocity of the output gear. The gear ratio is very important when it comes to physics.
The fastest gear ratio for achieving maximum speed in a vehicle is typically the highest gear ratio, such as overdrive gear. This allows the engine to operate at lower RPMs while maintaining high speed, resulting in better fuel efficiency and top speed.
No, the gear ratio is determined by the number of teeth in the ring gear and pinion gear. To be changed, that would require a physical alteration, which a speed sensor cannot do.
