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 gears are good for street racing?
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 gear is best for speed?
The gears determine the amount of power available from the engine. First gear provides the most pulling power but the least potential for speed, whilst fifth gear which provides the least pulling power allows the greatest range of speed.
Which gear ratio is best for high speed?
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.
Can I run 33s on 3.73 gears?
With 3:73 gears and 33" tires you are fine.
23 related questions foundAre 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.
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.
What are 4'11 gears good?
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).
What's the difference between 3.15 and 3.55 gears?
The 3.55 will make the gears seem shorter meaning you will shift more often. The trade off is faster acceleration for less gas mileage with the 3.55's and vise versa with the 3.15's.
What gear should I drive in?
A good rule of thumb is: higher gears and easy throttle equals less torque and the least amount of wheel spin. Lower gearing and more throttle equals more torque and the most amount of wheel spin. Downhill: Use first gear when driving downhill as a primary source for braking.
What is 4th gear used for?
You'll use 4th gear in a car for: Gaining speed after changing from 3rd gear. Driving around towns and cities at a speed of around 30 mph or so. Gaining a little more power or acceleration by changing down from 5th or 6th gear.
Are 3.42 gears good for highway?
The 3.42 gears do run well on the highway though, not much over 1900 rpms at 70.
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.
Are 410 gears good?
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 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.
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.
Are 3.25 gears good?
3.25s are a good all around gear.
Is 3.31 or 3.55 axle ratio better?
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.
Are 3.55 gears good for racing?
3.55 is great for stock power levels. A 400 hp 351 is nearly double stock power. If its a street car I'd say 3.27 or 3.08 if you plan a lot of long trips and really want to cruise. "There is little difference between 3.55 and 3.73" you hear this all the time and its true.
WHAT WILL 4.10 gears do?
Lower 4.10:1 gears would make the engine turn 4.10 times for each turn of the tire, so lower gears cause higher engine rpm at any road speed. If you continue to visualize the example of removing lug nuts with the long or short wrench, it will help you understand how to gear your car for quarter-mile acceleration.
Does low range increase torque?
Lower gears (as lowrange) reduces speed, but increases torque at the wheels.
