Are 3.08 Gears Good For Highway?

3.08 with a 3 speed auto is a good highway gear, but its pretty doggy in acceleration.

What are 3.08 gears good for?

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.

What is the best gear for highway driving?

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”.

What is a good highway gear ratio?

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 a 3.08 gear good for towing?

The 3.08 truck was fantastic for interstate cruising above 75 MPH. Brusly, La. Trade it in on a Toyota Tundra 5.7, with tow/ haul. If you have the 6 speed transmission, the 3:08 gears do a very good job.

What gears are best for racing?

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 a 3.23 good for towing?

The higher the ratio, the better the towing power but lower the fuel economy and speed. The lower the ratio, the better the fuel economy and speed but lower the towing power.If you’re looking for a higher towing capacity, choose the 3.42 rear axle ratio. If it’s optimal fuel economy you’re after, choose the 3.23.

Is a 3.25 gear ratio good?

3.25s are a good all around gear.

What gears for what speed?

Remember each car will be geared slightly differently, but a good rule of thumb for changing gears is that first gear is for speeds up to 10 mph, second gear is for speeds up to 15 mph, third gear is for speeds up to 35 mph, fourth gear is for speeds up to 55 mph, fifth gear is for speeds up to 65 mph, and sixth gear

What are highway gears?

Lower gears often called highway gears mean usually you will be slower out of the hole as compared to higher gear ratios. Some massive torque engines can compensate for lower gears and manage to get rolling quickly despite not having steep gears. The lower the gear the higher the top speed.

Which gear ratio is 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.

Is a 3.42 gear ratio good?

For instance, the 3.42:1 ratio included on many Canyon V-6 and Sierra 1500 models offers a good all-around blend. That said, if you regularly tow heavy trailers or prefer a peppier feel in acceleration, consider a truck equipped with a higher numeric axle ratio.

Is a 3.92 rear axle ratio good?

But opt for the higher 3.92 axle ratio and that same truck packs a higher towing capacity of 9,930 pounds. The extra towing capacity comes about because the increased engine spinning helps improve off-the-line acceleration and pulling power when carrying heavy loads.

What is a 3.08 rear axle ratio?

The ratio of the sizes of those gears is represented by the diameter of the gear that drives the wheels in relation to the gear from the driveshaft. So, a 3.08:1 ratio indicates the drive gear has 3.08 times as many teeth as the gear on the driveshaft.

Are 308 Gears good for towing?

Yes, you are exactly right, towing with a 6 speed with 3.08s is still better than towing with a 4 speed and 3.73s.

What is a good highway gear for a TH400 transmission?

TH400 gear multiplication with a 3.08 will net you decent highway mileage at the expense of bottom end acceleration. Whereas a 4.10 rear end will snap your neck with a stout motor in 1st, but you’d be stopping for gas much more often and be taching out at high rpm at highway cruising speeds.

Is 3.31 a good gear ratio?

Normally, the 3.31 would get you better gas mileage, on highway. But, with the 3.55 you will get a bit more pulling power so less time at higher RPM to get your trailer moving and when going uphill. If most of your towing is flat highway, the 3.31 should do you fine.

Is a 3.23 axle ratio good?

3.23 will be better suited to highway cruising and better fuel economy. 3.42 for better acceleration and better towing performance.

What are 3.21 gears good for?

The 3.21 hits 60 right after shifting into 3rd. – towing: for trailers at or under 8k, the 3.21 is fine. Yes it will operate one one gear lower pretty much the whole time, and be a little slower from a stop, but easily plenty of power.

What is the difference between 3.42 and 3.73 gears?

In short, the core differences are the 3.73 gear ratio gives you a lot more acceleration and torque, the 3.43 has a higher cruising speed and better fuel economy. The question of which one is the better option can best be answered by the specific application intended for your vehicle.

How do I choose the best 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.
