How do you find the gear ratio on a GM rear end?
Count the teeth on the small gear in the forward part of the axle housing, called the pinion gear. Count the number of the teeth in the big ring gear attached to the differential. Divide the number of teeth on the pinion into the number of teeth on the ring gear. This is the gear ratio.
How can you tell the difference between a 3.73 and a 4.10 gear ratio?
So for gear ratio of 3.73, for every one turn of the ring gear, the pinion will turn 3.73 times and for gear ratio of 4.10, for every one turn of the ring gear, the pinion will turn 4.10 times. The ratio is the number of teeth on the driven gear (ring) divided by the number of teeth on the drive gear (pinion).
What is the rear axle ratio?
Axle ratio refers to the gears in a truck's differential, which connects the rear axle to the driveshaft and then the engine. This ratio expresses a truck's towing capacity and fuel economy, and the relationship between the two.
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.
Will VIN number tell me gear ratio?
The Gear Ratio Could Be In Your VIN Code Or Identification Plate. ... Every number and letter within a VIN reveals information about the automobile, such as the make, model, year built and the engine size.
What diff ratio do I need?
Higher ratios are better for freeway driving since they run at lower RPM's and offer better fuel economy. ... If you originally had 3.07 gears you need a ratio that is approximately 17% lower, such as 3.55. If you want to increase off road performance you might want a 4.10 or lower ratio.
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. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing.
What are 373 gears good for?
In a 3.73:1 gear set, the pinion gear turns 3.73 times for every rotation of the ring gear. A higher gear ratio, like 4.11:1, will allow for faster acceleration, but will lower the potential top speed of the car. Ratios in the 4:1 range will be more suited to short track, drag racing and autocross.
What is a 373 rear end?
3.73:1 is a "higher" gearing, meaning that you have less torque, a higher top speed, and each gear will be a little bit farther apart. 4.11:1 is a "lower" gear ratio, meaning you have more torque, lower top speed, and you will generally consume more fuel.
How do you find the gear ratio on a 2016 Silverado?
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.
Is 3.73 a good gear ratio?
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.
How do I identify my Chevy truck rear end?
All Chevrolet rear ends can be identified by comparing the gasket shape to an identification chart similar to the one found on Drivetrain's differential identification page (see References). A visual chart of different GM/Chevrolet rear ends is found on Ring & Pinion's differential types web page (see References).
