Does gear ratio affect horsepower?
Motor HP does not change when you change gear ratios.
A dynamometer measures torque and RPM, and from those two values calculates horsepower.
When you change gear ratios both RPM and torque will change but horsepower will not..
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 are 4.88 gears good for?
Pros and Cons. The pros are that these gears have a stronger V6 third member (in the rear) with lower gears that are suitable for larger tires, and (most importantly) they can be had for less than a full ring and pinion install. If you have an IFS truck, you can swap in the 4.88 IFS front diff.
Does bigger tires change gear ratio?
Taller than stock tires alter the final drive ratio of your 4×4 at the tires and effectively decrease the power you can put to the ground. The bigger the tires are, the more noticeable the change. The added weight and wind resistance also tax the engine.
What is a good gear ratio for 35 inch tires?

How fast can you go with 4.10 gears?
With stock size tires you can go 150 mph at 5393 rpm in 5th gear.
Is 3.55 a good gear ratio?
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 3.73 or 4.10 gears better?
Vice versa, if the gear ratio is lower it has worse acceleration but a higher top speed. So, by changing your gear ratio, no power levels are being changed, just the torque….WHICH GEAR RATIO IS FOR YOU?3.73 RATIO4.10 RATIOBetter gas mileageWorse gas mileageHigher top speedLower top speed2 more rows•May 12, 2020
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 3.55 gears good for highway?
Well, if you plan on doing a lot of freeway driving, you don’t want to choose a gear that’s too low for your car because you’ll be going down the freeway at too high of an RPM. … Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc.
Is 3.42 or 3.73 better?
The difference in towing mpg between the 3.42 and 3.73 gears at highway cruise speed, under the same conditions, should be less than 1 mpg because of the slightly higher rpm running 3.73s. Vehicle speed actually plays a bigger role in fuel economy than engine rpm.
Do 3.73 gears make a difference?
The 3.73’s don’t go quite that far — but they’re with 10% of that change. So it will be a VERY noticeable difference. Highway fuel mileage will take a bit of a hit; city mileage has the potential to improve with the 3.73’s. All this assumes your rear tire height stays the same.
What is the best gear ratio for a street rod?
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 3.73 a good gear ratio?
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.
Does 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.
What are 4.11 gears good for?
4.11:1 is a “lower” gear ratio, meaning you have more torque, lower top speed, and you will generally consume more fuel. Usually people put 4.11:1 gears in trucks to be used off-road for the extra torque and the better “crawling” capabilities.
What 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.
What gear ratio is best 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.
