What rear end ratio 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..
Is 3.42 or 3.73 better?
3.73 is 9% higher than 3.42. That means your RPMs at any given speed will be 9% higher. You should be able to accelerate about 9% faster, in the lower gears at least. Your maximum speed in each gear will decrease by 9%.
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 is the best gear ratio 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.
How much horsepower can a 9 inch rear end handle?
Sure a 9 inch can handle 400+ horse in a car.
Is 3.08 a good gear ratio?
Yes, you are exactly right, towing with a 6 speed with 3.08s is still better than towing with a 4 speed and 3.73s. If its a heavy trailer, you will probably never use 5th and 6th gears, but who cares? crank turns to rotate the rear wheels once that counts.
Are 3.73 or 4.10 gears better?

Is a 3.42 gear ratio good?
Lower numeric axle ratios may help reduce how much an engine has to work while cruising at highway speeds, and can potentially help improve fuel economy. … For instance, the 3.42:1 ratio included on many Canyon V-6 and Sierra 1500 models offers a good all-around blend.
Is a 3.73 rear end good?
A 3.73 ratio is suitable for regular light towing. If you plan on towing a fifth-wheel trailer or anything heavier than 5,000 pounds, you should consider a 4.1 axle ratio. A 4.1 ratio allows a towing vehicle to start moving without as much throttle.
Is 3.55 or 3.73 gears 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.
What gear ratio is best for fuel economy?
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. The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy.
What is the difference between 3.73 and 4.10 gear ratio?
A 3.73 is a higher gear ratio for half ton pickups its not the best gear for pulling trailers, now the 4.10 gears come stock from the factory on newer trucks and is one of the best rear end gears to use if you plan on pulling a trailer. These both vary by fuel mileage consumption so choose wisely.
Are 4.10 gears good for 35s?
Yes, I’m running 35s on stock 4.10s here, with auto tray. It’s fine.
Does gear ratio affect horsepower?
Here’s what the numbers mean, how they relate, and how they affect performance: Torque is a measure of the rotational force applied to the engine’s crankshaft and ultimately to the drive wheels. … A higher numeric axle ratio (4.11:1) keeps the engine running in the higher horsepower range, thus improving performance.
Does changing gear ratio affect gas mileage?
Gear Ratio Effect The effect is generally minimal and will account for less than a single mile per gallon, and typically the gains are generally seen at highway speeds. … The transmission gearing directly affects the fuel economy at a given speed. The engine’s rpm and fuel consumption are generally lower in higher gears.
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”.
Is 3.73 gears good for towing?
FACT: A 3.73 axle ratio is ideal for towing heavy loads on flat terrain and will produce increased fuel economy during steady-state, long-distance highway driving. FACT: One of the major contributing factors affecting a truck’s fuel economy is aerodynamic drag.
Is it better to have a higher or lower gear ratio?
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.
