Is It Better To Have A Higher Or Lower Gear Ratio?

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”..

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.

Do 4.10 gears make a difference?

simply a higher gear ratio means less speed but more torque, for example in the cars, the 1st gear in the transmission the gear ratio is 4.10 and the 2nd gear the gear ratio will be 3.73 ….. to the 5th 0.75 (for example). The 4.10 will give slightly better acceleration and increase engine rpm at any given speed.

What is the best gear ratio for drag racing?

With a 3.08:1 rear gear, the effective First gear ratio is equal to a 2.20:1 First gear Muncie four-speed with 4.56:1 rear gear. In the quarter-mile, Fourth gear is equivalent to running a 3.79:1 rear gear. But shift into 1:1 Fifth gear and enjoy the highway cruising rpm of a 3.08:1 rear gear.

How does changing sprocket size affect speed?

Want the short answer? Gearing down by installing a larger rear sprocket (like with our YZ example) increases the final drive ratio and reduces top speed, but can increase acceleration. Gearing up, like with a smaller rear sprocket, decreases the final drive ratio and adds more top speed to your motorcycle or ATV.

What gear ratio is better for torque?

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.

What’s the best gear ratio for 35 inch tires?

Depending on the axle, the next lowest ratio from a 4.10:1 is most likely the 4.56:1, which should be selected for towing and performance. Because of the extra weight associated with off-road tires, we usually recommend going with a performance-minded gear ratio for any tire size above 35 inches.

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.

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 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

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.

How fast can you go with 4.10 gears?

With stock size tires you can go 150 mph at 5393 rpm in 5th gear.

Why is a higher gear ratio better?

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.

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.

Is a 4.10 gear ratio good?

FACT: A 4.10 axle ratio is ideal for towing heavy loads in a mix of city and highway driving and when towing on varied or steep grades. A 4.10 axle ratio will provide improved acceleration in stop and go city traffic.

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.

Does more gears mean more speed?

Having more gears allows smaller, more economical engines to power larger vehicles or improves the efficiency of existing engines. … The new seventh gear is taller, lowering engine rpm at any given speed, thereby decreasing fuel consumption and CO2 output without compromising acceleration or top speed.”

What is the best 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.
