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.
in fact, 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.
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 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 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”.

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 300 a lot of horsepower?
Under 300 Horsepower
For the average sedan, horsepower between 200 and 300 will offer much more potential under the gas pedal. … Right between 200 and 300 horsepower is the sweet spot for many drivers. Be cautious with models that approach 300 horsepower, unless the vehicle is a heavy truck or another large model.
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 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.
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 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.
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.
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 is a 3.73 gear good for?
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 3.25 a good gear ratio?
3.25s are a good all around gear.
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.
What is the fastest cheapest car?
- Ford Mustang. The Ford Mustang earns the top spot as the fastest, most affordable sports car. …
- Dodge Challenger. An American muscle car ranks second, the Dodge Challenger two-door coupe. …
- Chevrolet Camaro. …
- Hyundai Veloster N. …
- Mazda MX-5 Miata. …
- Subaru BRZ. …
- Toyota 86. …
- Fiat 124 Spider.
Is 700 horsepower a lot?
Before it was a rarity and luxury to buy a car that was 200-500 horsepower, now it’s getting pretty common. In fact, 700 horsepower is the new 500 horsepower, and every performance car worth its weight in carbon-fiber diffusers is packing either a now-standard supercharger or a turbo.
Is 1000 horsepower a lot?
Over 700 hp is attainable now by splashing some cash at the dealer, but 1,000 hp still isn’t typical, although more and more cars are grabbing headlines with that magic number. If you want to experience the rush of 1,000 hp or more, these are the cars to do it in.
Why does torque drop at high RPM?
At high RPM, torque drops off primarily from intake and exhaust flow restriction. Volumetric Efficiency declines because the engine can’t breathe any faster. Mechanical efficiency also declines at higher RPM, due to increased frictional resistance. This further reduces torque at the output.
Does higher torque mean faster acceleration?
A car with more hp than torque will always be quicker since this gives a car acceleration and speed. … This is why low-end torque becomes important for better acceleration in many scenarios. Higher torque doesn’t mean one vehicle will necessarily be faster than another, though.
Does torque increase with speed?
Since the rated output power of a motor is a fixed value, speed and torque are inversely related. As output speed increases, the available output torque decreases proportionately. As the output torque increases, the output speed decreases proportionately.
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 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.
