What gear ratio is best for 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.

in fact, 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”.

for instance, Are 3.73 or 4.10 gears better?

4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster.

indeed 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.

Is 3.42 or 3.73 better?

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 3.73 or 4.10 gears better?

3.73 VS 4.10 Ratio

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.

Are 4.10 gears good for 35s?

4.10 will be just fine for 35’s and Especially if you get a 4:1 transfer case for off road adventures. I recently went from 3.21 to 4.10 with 35″ Terra Grapplers. It made a huge difference on my 2dr with manual transmission, It’s just about perfect around town. I run at about 2400rpm at 70 in 6th gear now.

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 gear ratio is best for torque?

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.

What gear ratio is better for torque?

In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed. Meanwhile, a higher ratio will result in the opposite, i.e. more torque at the wheels but a lower top speed.

Is it better to have more torque or horsepower?

Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. … Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.

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.

Is a 3 42 gear ratio good for towing?

Re: Towing weight for a 5.3 with 3:42 gears

IMO, yes you can tow that trailer. I pulled an 7K trailer w/ my Sierra w/ 5.3 & 3:42. It may struggle a little going up some hills.

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 3.73 a good gear ratio?

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.

What are 4/10 gears good for?

The mechanical advantage provided by the lower gear ratio (4.10:1) means the engine doesn’t require as much effort to do the same work, more pulling power and higher rpm’s. It makes towing, and hauling, some off road situations and brisk take offs better, at the expense of highway fuel economy due to the higher rpms.

How fast can you go with 4.10 gears?

On the highway a 4.10 gear will only be about 200 rpms more at around 75 then a 3.73. And with the Automatic you will need all the help you can get. Top Speed of our GT’s should be between 145 and 155 depending on the tune of your chip if you have one.

Does a lower gear ratio increase torque?

In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed. Meanwhile, a higher ratio will result in the opposite, i.e. more torque at the wheels but a lower top speed.

What is a good gear ratio for 35 inch tires?

Gear Ratio And Tire Size Calculator

What gear ratio should you have for 35 inch tires?

Depending on the axle, the next lowest ratio from a 4.10:1 is most likely the 4.56:1, which should be selected for towing and performance. Because of the extra weight associated with off-road tires, we usually recommend going with a performance-minded gear ratio for any tire size above 35 inches.

Will gears make my truck faster?

The simple answer is yes. More aggressive gearing creates a quicker car but not a faster car. A gearing change will have a noticeable affect on your car. If you swap in taller rear gears, you can gain some top-end speed, making your car faster, but you’re going to be a bit slower leaving from a stop.

Is 3.55 or 3.73 gears better?

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. Similarly, a pickup with a 3.73 axle ratio will be faster than one with 3.55s.

Does bigger tires change gear ratio?

If the Tires Are Bigger, the Gears Should Be Lower. … Going to lower gears (ironically, a numerically bigger ratio) will increase the rpms of an engine (taking for granted the same diameter tire and going the same speed).
