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..
Does gear ratio affect horsepower?
Motor HP does not change when you change gear ratios. The only thing that changes is torque. 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.
How much does it cost to change the gear ratio in a truck?
As to cost, depending on where it is done, it could cost you as little as 750 dollars to as much as 1500 dollars per axle.
Is 3.23 a good gear ratio?
The engineers likely chose the numerically low gear ratio for fuel economy reasons. … A later swap to a four-speed and 3.23 rear gears woke up the performance of the car considerably. Yes, highway rpm increased as well, but I rationalized it by deciding that 3.23 gears provided a good balance of performance and economy.
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.
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”.
Does gear ratio affect gas mileage?
The choice of a numerically higher axle ratio will only knock off about 1 mile per gallon from the truck’s fuel economy. … But if you do a lot of high-speed driving, you might want to consider a vehicle with a numerically lower gear set to decrease engine rpm and improve fuel economy.
Are 3.73 or 4.10 gears better?

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 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.
Does higher gear ratio mean faster?
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.
Is it better to have a higher or lower gear ratio?
A numerically higher ratio — say, 3.9 as opposed to 3.2 — can pull heavy loads much better but has a worse fuel economy and lower speed. By contrast, a numerically lower ratio has better fuel economy but worse torque and towing power.
What gear ratio do I have by Vin?
Check the bolts on the differentials. There should be a tag on one of them. The codes on that tag will tell you the gear ratio. The VIN will not give you gear ratios in most cases.
What is the best gear ratio for speed?
If you prefer top speed to dragstrip performance, then higher axle gears, like 2.76:1 or 3.08:1, may be called for. The higher gears will reduce engine rpm versus road speed. Another way to look at it is that the car will go faster at the engine’s rpm limit than it would with lower gears.
