Gear Ratio: the ratio of the ring and pinion gears in the rear axle. So, if you have a 4.10:1 (sometimes 4.10) rear axle, the pinion will turn 4.10 times for every single turn of the ring gear or in other words, for every 4.10 turns of the driveshaft, the rear wheel will spin once.
Is 4.10 a good gear ratio?
4.10 is the typical gear ratio for a high-performance vehicle like a sports car or SUV because it provides better acceleration than 3.73 because of the faster second and third gears, which provide more torque at lower speeds to accelerate from a stop.
What are 4/10 gears good for?
This equates to a greater amount of power transferred to the wheels. Installing 4.10 gears improves the car's performance on the track but with negligible effects to the highway driving. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing.
How can you tell the difference between a 3.73 and a 4.10 gear ratio?
3.73, for every 373 rotations of the driveshaft you get 100 rotations of the axle, and for 4.10, for every 410 rotations of the driveshaft you get 100 rotations of the axle. Now, this means that your engine is spinning faster on 4.10 rather than 3.73.
Is a 4.10 gear ratio good for towing?
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.
16 related questions foundAre 3.73 or 4.10 gears better for towing?
For towing, the 4.10 is better. For a heavier load, I would agree that the lower gearing is better. For a light load (4k lbs), 3.73's would do just fine. If you foresee towing heavier loads in the future (getting a larger TH, etc), then 4.10's would be the better choice.
What is the best gear ratio for 33 in tires?
4.56 works well for the 3-speed automatic and 33's, 4.88 is optimal for the 5-speed manual transmission.
How do I figure out what gear ratio I need?
To calculate the gear ratio:
Divide the number of driven gear teeth by the number of drive gear teeth. In our example, it's 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.
What is a good gear ratio for a street car?
If we have a daily driver, 2.55 to 3.25 gear ratios typically work best, whereas a street/strip application we would usually use a 3.42 to a 3.90 gear ratio, and race applications most commonly use a 4.10 and above gear ratios.
What's the difference between 4.10 and 4.11 gears?
4.10 will have 41/10 teeth so more, but smaller for the same diameter ring. 4.11 will have 37/9 teeth which will be larger. The 4.10 is a stronger pinion.
What are 3.92 gears good for?
4) 3.92 has 3 unique lower gears for towing. 5) Speed range that 3.21 is better at towing: 31-38 MPH, 48-57 MPH. 6) Speed range that 3.92 is better at towing: 0-30 MPH, 39-47MPH, 58-70 MPH.
What is best rear axle ratio?
The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.
How fast can you go with 4.11 gears?
The Covair engine in good shape should be able to run continuously up to 4,000 RPM. With a 4.11 and a 7.00X13 tire that is about 69 MPH based on some rough calculations, or O.K. for freeway driving, but the engine will sound busy.
What are 4.11 gears good for?
If you go to a 4.11 you will increase your RPM at any given speed. Nice if you need more power at highway driving, climbing hills, restarting at stoplights etc.. 4.11's make your truck "feel" like you have more HP from stoplight to stoplight and pulling hills.
What does a 410 rear end mean?
Gear Ratio: the ratio of the ring and pinion gears in the rear axle. So, if you have a 4.10:1 (sometimes 4.10) rear axle, the pinion will turn 4.10 times for every single turn of the ring gear or in other words, for every 4.10 turns of the driveshaft, the rear wheel will spin once.
What does Regearing a jeep do?
Regearing is the process of changing your pinion gears and ring gears to a different ratio, which changes the balance of torque and speed. Regearing your Jeep is a crucial step in adjusting the size of your tires since improper gearing can result in more stress being transferred to the axle.
Does gear ratio affect horsepower?
A higher numeric axle ratio (4.11:1) keeps the engine running in the higher horsepower range, thus improving performance.
Which gear ratio is faster?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.
What is the best gear ratio for a muscle car?
If it's a daily driver, chances are you'll want to keep your gear ratio at 3.23 or below for optimal performance and lower cruising RPMs. For street and strip applications, a popular choice ranges between 3.42s and 3.90s, giving you that extra oomph on the track while maintaining a tolerable cruising RPM on the street.
Do bigger tires affect 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. You do not want go too low in an effort to increase power to the wheels and/or relieve stress in the rest of the drivetrain.
What is the gear ratio of a th350?
Gear ratios vary, but the Turbo 350 typically has a first gear ratio of 2.52 to 1.00; 1.52 to 1.00 for second; direct drive in third; and 2.07 to 1.00 in reverse.
How do I choose final drive ratio?
To find the ideal selection, multiply the final drive ratio by the redline speed in fourth gear (152 mph) and divide that by the top track speed (140 mph). This would yield a theoretical 3.33—which is close enough to the nearest available final drive ratio of 3.36:1.
What gear ratio is a Dana 35?
Dana 35 3.08-5.13 Ratio.
What is the best gear ratio 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.
