Where do I find the gear ratio on my car?
How to Find Out the Gear Ratio With the VIN Number. It can be found on the sticker on the inside of the driver’s side door or on a stamped metal plate embedded in the dashboard above the steering wheel. It also is on your vehicle’s title. Identify the VDS section, the fourth through eighth digits of the VIN.
What’s the difference between high and low gear ratios?
Higher gear ratios (lower numerical axle ratio) provide better acceleration/torque, and lower gear ratios allow higher top speeds and better fuel economy. A vehicle with a high gear ratio runs faster to produce more power and achieve a given speed. Lower gear ratios ensure the engine runs more economically to maintain a given speed.
What happens to a truck with a low axle ratio?
A truck with a low axle ratio number means the vehicle will go faster and improved fuel economy, but lower towing capacity. The vehicle’s engine will work less when speeding on highways.
How does gear ratio affect speed and torque?
When the rear end gear ratio is 1:1, the amount of speed and torque is similar. Therefore, when you increase the axle ratio, you reduce the amount of torque and significantly increase speed, and if you reduce the axle ratio, you reduce speed and boost the torque.
How do you find out what your gear ratio is?
Count the number of teeth on the drive gear. One simple way to find the gear ratio between two interlocking gears is to compare the number of teeth (the little peg-like protrusions at the edge of the wheel) that they both have. Start by determining how many teeth are on the drive gear.
How to tell which gear ratio I have?
Part 3 of 5: Determining an approximation of your car’s gear ratio Place a visible mark on the driveshaft near the differential housing. Use the chalk or paint pen. Spin the driveshaft by hand. While spinning the driveshaft, count the revolutions by watching the markings, as well as counting the revolutions of the tire at the same Continue spinning the driveshaft.
How do you determine axle gear ratio?
- Slide a floor jack under the rear of the vehicle and raise it until the rear wheels are off the ground.
- Crawl under the vehicle and locate the drive shaft where it attaches to the front of the rear axle.
- Place a piece of masking tape on the edge of one of the rear tires.
How do I determine my axle gear ratio?
When attempting to find the axle ratio of an unknown gear set-up, it is possible to count the teeth on both the ring and pinion gears and divide the number of teeth on the ring gear by the number of teeth on the pinion gear. The result is the final gear ratio of the axle.
