What Is A Good Gear Ratio For 35 Inch Tires?

What gear ratio should I use for 37 inch tires?

Increasing the 4.10 axle ratio by 16 percent would dictate the need of a 4.75 axle ratio to match the 37-inch tires.

The exact axle ratio you need probably won’t be available, so it’s okay to round up when selecting the right ring and pinion.

In this case, a 4.88 axle ratio would be acceptable..

Is it better to have a higher or lower gear ratio?

A high numerical gear ratio is called a low gear or low rear end, and vice versa. Low gears give fast acceleration, high gears give better cruising. A smaller engine will need a lower rear end to give adequate acceleration.

What are 4.88 gears good for?

The pros are that these gears have a stronger V6 third member (in the rear) with lower gears that are suitable for larger tires, and (most importantly) they can be had for less than a full ring and pinion install. If you have an IFS truck, you can swap in the 4.88 IFS front diff.

Are 3.73 gears good for highway?

Well, if you plan on doing a lot of freeway driving, you don’t want to choose a gear that’s too low for your car because you’ll be going down the freeway at too high of an RPM. … Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc.

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 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.

Are 4.10 gears good for 35s?

Registered. the general reaction is going to be yes re-gear, unless you dont mind the loss of low end power and never using OD. Back in the day i use to beat up my TJ on 33s with 3.73s since i didnt know any better and i was fine. At the very least you can run your 35s with 4.10 until you get around to re gearing.

Do you need to Regear for 35 inch tires?

No you don’t HAVE to regear, but your going to lose you top end power. I have roughly 34in tires with the stock 3.73 on an auto and I drive a lot of free way with a few mountain ranges. It is not pleasant. I plan on regearing once I get the money saved up.

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.

Can Dana 30 Handle 35 tires?

Yes, you may twist your axle housing or explode the carrier running 35s, but you could do just the same running 33s. … Dana 30 (and 44) JK frontends will also benefit greatly from the installation of HD ball joints, axle shafts, and extra housing reinforcement, such as a truss.

Is 3.55 a good gear ratio?

For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. … BEST TOWING RATIO: In general, the best towing axle ratio for most of the post-2010 pickups is in 3.55 or 3.73. Those ratios provide very good acceleration with gas V-8s and diesels.

What gear ratio is best for fuel economy?

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. The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy.

What gear ratio is best 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.

How fast can you go with 4.10 gears?

On the highway a 4.10 gear will only be about 200 rpms more at around 75 then a 3.73. And with the Automatic you will need all the help you can get. Top Speed of our GT’s should be between 145 and 155 depending on the tune of your chip if you have one.

Is 3.73 a good gear ratio?

Two common base axle ratios for trucks are 3.08 and 3.42. 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.

What’s the difference between 4.10 and 3.73 gears?

Use this rule of thumb: The higher the gear ratio, the easier it is to get the vehicle moving and better accelerating, but lowers top speed. Vice versa, if the gear ratio is lower it has worse acceleration but a higher top speed….WHICH GEAR RATIO IS FOR YOU?3.73 RATIO4.10 RATIOHigher top speedLower top speed3 more rows•May 12, 2020

What gear ratio is best for 33 inch tires?

So if our truck had 30-inch tires stock, and a 3.73:1 axle ratio, that calculation would tell us we need a 4.103:1 (which rounds off to the readily available 4.10:1) gear ratio to get us back to stock with 33-inch tires.

Do 3.73 gears make a difference?

Yes, while it’s a noticeable improvement in seat of the pants acceleration, you will run out of rpms quicker with 3.73s. In the long run you’ll find yourself looking for more engine rpms. The increased torque multiplication of lower gears will help make better use of a higher revving engine combo.
