How do I find my axle ratio?

How do I find my axle ratio?

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.

How do I know what rear end my Chevy has?

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.

What is the difference between a 10-bolt and 12-bolt rear end?

First, the 10-bolt’s pinion shaft diameter is 1.438 (25 splines) while the 12-bolt is 1.625 (30 splines) which makes the 12-bolt 13 percent larger in diameter and therefore stronger. The 8.2 uses a 28-spline axle (1.20 inches in diameter) while the 12-bolt uses a 30-spline axle (1.625 inches in diameter).

Why does only one wheel spin when I do a burnout?

In general, it’s because you don’t have a locking or limited-slip differential. In that case, if there isn’t equal traction for both wheels, the one with the least grip will steal all the power and start to spin.

Can every car do a burnout?

Burnouts began in drag racing, where tires must be heated to obtain the optimum traction on the racing surface. Plus it just looks cool. Unfortunately, you can’t burnout in any old car, but if you want to remove layers of expensive rubber to accomplish nothing of dynamic significance besides enjoyment, it can be done.

How do you get both tires to spin?

For both tires to consistently spin there would need to be a device (LSD, locker, or spool) to engage both shafts to give power to both wheels, not just the one that has the least resistance. Limited Slip Differentials A differential locker can make a world of difference when it comes to driving off-road.

Do burnouts damage your transmission?

Burnouts are just about the worst thing you can do to a transmission automatic or otherwise. It’s called a burnout for a reason: it will burnout your transmission.

How do I find my axle ratio?

How do I find my axle ratio?

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.

Can you tell axle ratio by VIN?

Contact the dealer or the manufacturer (you could get a customer service number from the owners manual of the truck) and give them the VIN number and tell them you wish to know the axle ratio. They may only need certain digits from the VIN to determine, but it’s better to have them all in case.

How do I find the axle ratio on my Silverado?

To find the axle gear ratio of any GM vehicle, locate the RPO sticker (typically located in the glove box) and write down any codes starting with F, G, or H.

Do front and rear axle ratios have to match?

Final drive ratios must be the same. A diff doesn’t have a ratio and is always the same, ie, One wheel stopped, the other side twice the speed. All diffs are the same. Any difference in final drive ratios front to rear will cause failure unless a centre diff is running the DIFFERENCE of speeds.

What axle ratio does my RAM have?

Ram has a standard axle ratio of 3.21 on 2X4 trucks and 3.55 on 4X4 trucks and trucks with the diesel engine.

How do I know the axle ratio of my Ram 1500?

Start the truck and put it into neutral. Rotate the rear tire 2 times and count the number of times the drive shaft turns. Close to 4 times = 3.92. Close to 3 1/2 = 3.55 Close to 3 = 3.21.

What is axle ratio Ford?

The axle ratio refers to the gears in the truck’s differential, which is a mechanical device that links the rear axle to the driveshaft and then the engine. Four-wheel-drive trucks will have a matching ratio in the front axle’s differential.

Is a 3.92 axle ratio good?

Which axle ratio you go with will affect your truck’s towing capability, but fuel economy will change too. A higher axle ratio (like the 3.92 we mentioned earlier) will allow for higher towing capability, but it requires higher engine rpm for any given speed and then results in lower fuel economy.

What gear ratio is better for towing?

A lower gear (higher numerical) ratio provides more low-speed wheel torque, which makes it easier to get the vehicle moving when pulling a trailer or carrying a heavy load. A 4.10 rear axle ratio is ideal for towing larger 5th Wheel or Gooseneck trailers.

What is the difference between 3.73 and 4.10 axle ratio?

A 3.73 is a higher gear ratio for half ton pickups its not the best gear for pulling trailers, now the 4.10 gears come stock from the factory on newer trucks and is one of the best rear end gears to use if you plan on pulling a trailer. These both vary by fuel mileage consumption so choose wisely.

What is better 3.21 or 3.92 axle ratio?

From the speed 48-57 MPH, 3.21 has higher final drive ratio over 3.92 (10.10 vs 8.23) until it has to shift to 3rd gear at 57 MPH. From the speed 58-70 MPH, 3.92 has higher final drive ratio over 3.21 (8.23 vs 6.74) until it has to shift to 4th gear at 70 MPH.

Are 4.11 gears good for highway?

4.11 is a big jump from 3.73. If you dont do any 50+ mile highway drives, and keep it “around town”, you could be OK with 4.11’s. Tire size has a big effect on your overall gearing.

What is the axle ratio?

The axle ratio refers to the gears in the truck’s differential, which is a mechanical device that links the rear axle to the driveshaft and then the engine. Four-wheel-drive trucks will have a matching ratio in the front axle’s differential. This is a good ratio for the occasional towing or hauling individual.
