Can you change gear ratios?
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.
How do I choose transmission gear ratio?
To find the ideal selection, multiply the final drive ratio by the redline speed in fourth gear (152 mph) and divide that by the top track speed (140 mph). This would yield a theoretical 3.33—which is close enough to the nearest available final drive ratio of 3.36:1.
How much does it cost to change your gear ratio?
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. Best prices would probably be a performance shop that does it all the time.
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?
It doesn’t affect horsepower or tourqe at all. Gears make your rear tires turn faster or slower. It also effects your top end speed and milage. The reseaon you dyno in 4th gear is becouse its a 1-1 ratio.
What gear ratio is better for acceleration?
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”. If you take lower gears to accelerate quickly from 0-60, you will give top-end speed.
What’s the difference between 4.10 and 3.73 gears?
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 RATIO||4.10 RATIO|
|Lower torque||Higher torque|
|Better gas mileage||Worse gas mileage|
|Higher top speed||Lower top speed|
What gear ratio is best for fuel economy?
Automakers Offer Variety of Axle Ratios Step one in understanding axle ratios is to know what the numbers signify. 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.
What is the best first gear ratio?
For most street performance applications, a 10:1 final First gear ratio is usually considered optimal. The disadvantage of operating a 4.10:1 axle ratio on the street with a 1:1 high gear is excessive freeway engine speed.
Can you change the gear ratio on a truck?
Yes, just changing the front and rear ring and pinion will change the gear ratios. It is advisable to also replace the pinion seal as well as the crush sleeve and the pinion nut.
How much does it cost to change rear gears?
Are there a lot of parts to replace or just a few? Heavy repairs range from $400-$800, while lighter repairs should cost anywhere from $200 to $400.
How much does it cost to change the gear ratio in a Jeep Wrangler?
$1,500-$2,000 installed depending on shop.
Is 3.73 gears good for towing?
A 4.10 rear axle ratio is ideal for towing larger 5th Wheel or Gooseneck trailers. 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.
Are 3.73 gears good for racing?
3.73 s on most cars will just help you have more traction problems launching, 3.42s are good enough down low, yet still good up top.
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.
