Is a 3.55 axle ratio good for towing?

Is a 3.55 axle ratio good for towing?

It’s pure mechanics. 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.

Is a 3.31 axle ratio good for towing?

“The 3.31 might be capable of towing the trailer. But if you are towing the majority of the time, you probably want the 3.55 because it will tow better and provide better fuel economy loaded.” Start with the total combined weight of the vehicle. Note that pickup tow and haul ratings are listed by axle ratio.

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

A numerically higher ratio say, 3.9 as opposed to 3.2 can pull heavy loads much better but has a worse fuel economy and lower speed. By contrast, a numerically lower ratio has better fuel economy but worse torque and towing power.

What axle ratio is best for towing?


Is 3.42 or 3.73 better?

The difference in towing mpg between the 3.42 and 3.73 gears at highway cruise speed, under the same conditions, should be less than 1 mpg because of the slightly higher rpm running 3.73s. Vehicle speed actually plays a bigger role in fuel economy than engine rpm.

Can I change my axle ratio?

Replacing the Axles Ring and Pinion to Change Axle Gear Ratios. Of course, one way to get a different axle gear ratio is to replace the rear axle, but that could get pricey. The most common method is to change the axles ring and pinion. The ring and pinion are what creates the ratio in the axle’s differential.

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 •

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 much does it cost to change axle 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 3.23 a good gear ratio?

The engineers likely chose the numerically low gear ratio for fuel economy reasons. A later swap to a four-speed and 3.23 rear gears woke up the performance of the car considerably. Yes, highway rpm increased as well, but I rationalized it by deciding that 3.23 gears provided a good balance of performance and economy.

What is the difference between 3.73 and 4.10 axle ratio?

A 4.10 axle ratio will provide improved acceleration in stop and go city traffic. 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.

How do I find my axle ratio?

Here are two ways to find the axle gear ratio of a vehicle: Method 1: Count the number of teeth on the ring gear and the pinion. Divide the number of the ring gear’s teeth by the number of the pinion’s teeth. This will give you the axle ratio.

What gear ratio do I have by Vin?

Identify the VDS section, the fourth through eighth digits of the VIN. This section typically includes information such as the vehicle model, engine size and body type. While not every vehicle manufacturer includes gearbox ratio information in the VDS, this will be where the information is found if it was included.

How do I find my Silverado axle ratio?

Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box.

How do I know what gear ratio my front differential is?

How can I tell what gear ratio I have without pulling cover?

So an easy way to determine your actual gear ratio is to check the tag attached to the differential cover by the cover bolts. On the tag there should be some numbering such as 3.54 or 3.73, either of those numbers will give you the stock axle ratio.

How do I identify my GM front differential?

Information about Differentials in GM vehicles can usually be obtained by looking at the RPO or “Regular Production Option” codes contained in the Service Parts Identification tag in the glovebox. Whenever possible, reference the tag numbers when ordering parts for your Differential.

How do I find my front differential?

Visual Differential Identification Without an ID tag, differentials are identified by the number of cover bolts, the distinctive shape of the cover, the number of ring gear bolts, and ring gear diameter. They can also be identified by whether the center section is an integral or dropout design.

How do I know if I have a Dana 44?

This stamped number can usually be found on the righthand side or on the longer axletube on the same side of the tube as the differential cover, facing the rear of the truck. The number can be used to identify the axle, the year of manufacture, and the model vehicle the axle originally came from.

How do I know if I have a limited slip differential?

The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.
