For those huge 40 inch tires, 4.56 gears would be much better than 4.10. Actually, if you want to keep the RPM vs speed the same as the factory setting with those 40 inch tires, you would need something like a 4.90 gear ratio.
What are 4.10 gears good for?
4.10 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.
How do I choose the right gear ratio?
TRACK-OUT GEARING
The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
What are 411 gears good for?
4.11 is a gear ratio.. basically it means that the the pinion or driveshaft will turn 4.11 times for each rotation of the tires. The higher the ratio, the more times the the the engine, transmission, transfer case, etc turns to make the wheels spin which yields less top speed but more low end torque (usually).
Are 4.10 gears good for 37s?
4.10 gears do fine for me and I love the look of a more-filled wheel well. The 37s should run fine as a daily driver. The Spacers give the room needed for full flex.
37 related questions foundWhat gear ratio should I run with 37 inch tires?
Upgrading to 37-inch tires would calculate to about a 16 percent increase in tire diameter. Increasing the 4.10 axle ratio by 16 percent would dictate the need of a 4.75 axle ratio to match the 37-inch tires.
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 is the difference between 410 and 411 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 rear end gears should I use?
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.
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 is a good highway gear ratio?
The most popular rear-end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy. This is a good ratio for the occasional towing or hauling individual. For a person who tows more often, and heavier loads, the 3:73 or 4:10 may be more appropriate.
Are 410 gears good for highway?
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.
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.
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.
What is a 4.11 rear end?
A 4.11 refers to a 4.11:1 ratio. This means that the driveshaft turns 4.11 times for each time the axles turn once. This yields strong acceleration but, depending on transmission ratios, can mean the car cruises at high RPMs.
Can I run 33s on 3.73 gears?
With 3:73 gears and 33" tires you are fine.
What are 3.73 gears good for?
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.
Is a 3.55 rear end good?
BEST TOWING RATIO: In general, the best towing axle ratio for most of the post-2010 pickups is in 3.55 or 3.73. Those ratios provide very good acceleration with gas V-8s and diesels.
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 considered a low gear ratio?
A gearing ratio lower than 25% is typically considered low-risk by both investors and lenders. A gearing ratio between 25% and 50% is typically considered optimal or normal for well-established companies.
Is a 4/10 gear ratio good?
4.10 gears are just a great all around gear. Good for pulling and still half decent on your fuel mileage.
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 is the best rear end for drag racing?
Ford 9"- The Ford 9" is definitely the most popular of the rear ends in drag racing. It offers good strength characteristics and the largest variety of gear choices. The thirdmember type center section allows a racer to have multiple gear ratios available and is much easier to change than a rear loading type rear end.
