Luckily, some tuners, such as Sharkwerks, can alter the transmission’s gear ratios to improve acceleration and shifting frequency. There’s also the axle ratio to consider. As with the transmission, changing the axle ratio changes vehicle performance. A higher ratio means better acceleration, but worse efficiency.
Can you change gear ratios on a car?
Luckily, some tuners, such as Sharkwerks, can alter the transmission’s gear ratios to improve acceleration and shifting frequency. There’s also the axle ratio to consider. As with the transmission, changing the axle ratio changes vehicle performance. A higher ratio means better acceleration, but worse efficiency.
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 .
Can you change your final drive ratio?
The final drive ratio is the last bit of gearing between your transmission and the driven wheels. By changing it, you can affect the performance of your car, rather dramatically in some cases. In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed.
What does changing your gear ratio do?
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 the table below you can see the top speed in each gear for different final drive ratio’s.
Are 3.73 gears good for highway?
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.
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.
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. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.
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.
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.
Can gear ratio be less than 1?
Typically, gears 5 and sometimes even 4 have ratios less than 1, which means that engine RPM will be less than wheel RPM in those gears. For example, gear ratio for 5th gear can typically be 0.9. Such gears (with gear ratios of less than 1) are called overdrive gears.
Do 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.
How do you choose a gear ratio?
The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights , and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
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.
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.
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 .
