Can you tell gear ratio from Vin?
The vehicle identification number (VIN) is a 17-digit code that is used to identify and track every automobile produced.
Each number and letter contained within a VIN reveals information about the vehicle, such as the make, model, production year and engine size.
The codes on that tag will tell you the gear ratio..
Do smaller tires increase speed?
Down-sizing, or installing a shorter tire, will cause the speedometer to read a faster speed than you are actually driving. This is because the smaller tire will have a smaller circumference, causing the tire to travel less distance per rotation than the original equipment tire.
Is 3.42 or 3.73 better?
The difference in towing mpg between the 3.42 and 3.73 gears at highway cruise speed, under the same conditions, should be less than 1 mpg because of the slightly higher rpm running 3.73s. Vehicle speed actually plays a bigger role in fuel economy than engine rpm.
Does gear ratio affect horsepower?
Motor HP does not change when you change gear ratios. … A dynamometer measures torque and RPM, and from those two values calculates horsepower. When you change gear ratios both RPM and torque will change but horsepower will not.
What does a bigger gear ratio mean?
The higher the number the better the car will accelerate, but at the expense of high speed cruising. Now for the confusing part of the story. A high numerical gear ratio is called a low gear or low rear end, and vice versa. Low gears give fast acceleration, high gears give better cruising.
Is a 4.10 gear ratio good?
FACT: A 4.10 axle ratio is ideal for towing heavy loads in a mix of city and highway driving and when towing on varied or steep grades. A 4.10 axle ratio will provide improved acceleration in stop and go city traffic.
Should I Regear with 35s?
No, you don’t need to re-gear with 35s. However, definitely plan on a re-gear in the future and fall in love with your Jeep all over again. She loses pep with bigger meats without the regear – especially with the heavier 35″ tires.
What is the difference between 3.73 and 4.30 gear ratio?
A 4.30 ratio will give you better low end acceleration but also lower gas mileage. A 3.73 ratio will still provide decent acceleration but will also provide a tad better mileage plus give you a higher top end speed. Not that you are looking for a higher top end speed.
What’s the difference between 4.10 and 3.73 gears?
Use this rule of thumb: The higher the gear ratio, the easier it is to get the vehicle moving and better accelerating, but lowers top speed. Vice versa, if the gear ratio is lower it has worse acceleration but a higher top speed….WHICH GEAR RATIO IS FOR YOU?3.73 RATIO4.10 RATIOHigher top speedLower top speed3 more rows•May 12, 2020
Is 3.55 or 3.73 gears better?
A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.
Are 3.73 gears good for highway?
Rear end gears (2.79’s, 3.00’s, 3.25’s, etc) are great for freeway driving, bit not good for 0-60 MPH or accelerating from a dead stop. Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc. Always remember, for very “give” there is a “take”.
What gear ratio is best for fuel economy?
The lower the number, the better fuel economy, and the higher the number the more towing power you have, but fuel economy suffers. For instance, a 3:31 gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops.
Is it better to have a higher or lower gear ratio?
The gearing ratio is an indicator of the financial risk associated with a company. If a company has too much debt, it can fall into financial distress. A high gearing ratio shows a high proportion of debt to equity, while a low gearing ratio shows the opposite.
Do bigger tires use more gas?
For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.
Are 4.10 gears good for highway?
Installing 4.10 gears improves the car’s performance on the track but with negligible effects to the highway driving. … Switching from a gear set of 3.55 or 3.73 to 4.10 gears will affect your gas mileage slightly as your engine will be turning more times to rotate the rear wheels once.
What gear ratio is best for speed?
4.10:1In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.
Do taller tires increase gear ratio?
When changing gears for taller tires, you are heading to a numerically higher gear ratio. The higher the gear ratio, the smaller the pinion gear.
Does changing tire size affect gear ratio?
Tire diameter, along with rear-axle gearing, plays a role in the final drive ratio, which in turn affects acceleration and overall performance. … By doing so, you can determine the axle gearing you’ll need to use with your new tire diameter in order to maintain (or enhance) performance.
What gear ratio is best for 33 inch tires?
So if our truck had 30-inch tires stock, and a 3.73:1 axle ratio, that calculation would tell us we need a 4.103:1 (which rounds off to the readily available 4.10:1) gear ratio to get us back to stock with 33-inch tires.
What is a good gear ratio for 35 inch tires?
