Is 2.47 a good gear ratio?

For fuel efficiency, a low numeric drive axle ratio (2.24:1) gives you a low engine rpm (where all the torque lives) at cruise speed, thus reducing fuel consumption. A higher numeric axle ratio (4.11:1) keeps the engine running in the higher horsepower range, thus improving performance.

What is a good gear ratio for top speed?

In 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.

What does 4.10 gear ratio 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.

41/10 = 4.10 41/12 = 3.42 40/13 = 3.08

What are 3.55 gears good for?

PERFORMANCE: The larger the axle ratio number, the quicker the truck will accelerate. For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio.

Which axle ratio is best?

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.

Are 3.73 or 4.10 gears better?

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 best gear ratio?

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.

How do I choose the right gear 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 is a good street strip gear ratio?

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 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 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.

How many teeth does 4.88 gears have?

Motive Gear D35-488 Rack and Pinion, 39-8 Teeth, 4.88 Ratio.

How many teeth does a 342 ring gear have?

Pinion Set – 3.42 Ratio, 41-12 Teeth, GM 10 Bolt (70-94) 49-0278-1.

What is a pinion gear?

Pinion Gear – A pinion is the smaller of two meshed gears in an assembly. Pinions can be either spur or helical type gears, and be either the driving or driven gear, depending on the application. Pinion gears are used in many different types of gearing systems such as ring and pinion or rack and pinion systems.

Are 4.10 and 4.11 gears the same?

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.

Is 3.54 a good gear ratio?

3.54 are really low for towing that much weight. Truck will do it of course but you’ll get REALLY bad fuel mileage and you’ll find yourself pushing it and down shifting on grades, IMO. If you tow frequently I’d swap out gears to 3.73 or 4.10.

What does 411 gear ratio mean?

The ratio is the number of teeth on the driven gear (ring) divided by the number of teeth on the drive gear (pinion). So, if the ring gear has 37 teeth and the pinion has 9 teeth, the ratio is 4.11:1. That also means that for every one turn of the ring gear, the pinion will turn 4.11 times.

What are 3.31 gears good for?

Normally, the 3.31 would get you better gas mileage, on highway. But, with the 3.55 you will get a bit more pulling power so less time at higher RPM to get your trailer moving and when going uphill. If most of your towing is flat highway, the 3.31 should do you fine.

Is 3.55 or 3.73 better?

3.55 will give you a little better gas mileage on the highway and slightly more highway oriented performance. 3.73 may be better for towing, lower end power (off the line acceleration), and may result in worse gas mileage on the highway.

Which rear end 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 a 3.21 rear axle ratio good?

The standard 3.21 axle ratio then gets you a maximum tow rating of 8,440 pounds. Go with the 3.92 gearing and the tow rating jumps up to 11,540 pounds — a massive 3,100-pound difference. WILL HIGHER AXLE RATIOS AFFECT THE WAY MY TRUCK DRIVES? In short, yes.

Can you change axle ratio?

To counteract the effects of larger tires, you can change the gears in your differential(s) to increase the ratio of how many revolutions of the driveshaft it takes to make one full revolution of the wheel (raising the engine rpm at the same speed).

Which is better 3.21 or 3.92 axle ratio?

There’s a reason the 3.92 is an at-cost option. It’s the most preferable ratio. Having said that, if MPG is your primary objective, the 3.21 is the way go to with the diesel. On a gas engine, the RPM range is so great that gear ratio doesn’t make a lot of difference in efficiency.

How much does it cost to Regear your truck?

If you are looking to regear and can find an affordable shop, you could complete the whole project for around $1,500 or less. What is this? To break down the costs, you can expect a gear overhaul kit to cost anywhere from $600 to $1,200.

What are 3.42 gears good for?

The 3.42 is fine for towing smaller boats, plus you will get better gas mileage for everyday driving. If I were towing frequently on hilly roads, I might would go for the 3.73 for better gas mileage while towing, but the 3.42 should be fine with a 205.

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.
