How do I tell what gear ratio my Chevy truck 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..
Can you have different gear ratios front and rear?
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 does the 6th digit in a VIN number mean?
The letter or number in position 11 indicates the manufacturing plant where the vehicle was assembled. Each automaker has its own set of plant codes. The last six digits (positions 12 through 17) are the production sequence numbers, which each car receives on the assembly line.
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 can I tell what gear ratio I have without pulling cover?
With the transmission in neutral, rotate the rear driveshaft by hand. Count the number of driveshaft revolutions required for one revolution of the tire. If the driveshaft turns approximately 3-1/2 times, you have a 3.54 ratio, etc.
How do I find out what gear ratio my Ram truck has?
Active Member. You can always look at the tag on the differential. It has the ratio printed on it. You can also get your build sheet which is specific to your truck and lists all components used to build your truck.
Where is the RPO code on a Vin?
Yes, you can use a site such as Compnine.com, or you can take that VIN number to a GM dealer parts department and they can run a VIS report that will show all RPOs for the VIN.
How do you change the gear ratio on a truck?
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.
What gear ratio is best for 35 in tires?
Depending on the axle, the next lowest ratio from a 4.10:1 is most likely the 4.56:1, which should be selected for towing and performance. Because of the extra weight associated with off-road tires, we usually recommend going with a performance-minded gear ratio for any tire size above 35 inches.
How do I know what gear ratio my front differential is?
Pull off the diff cover and count the ring gear teeth and the pinion gear teeth, then divide the pinion gear into the ring gear. That will give you the exact ratio.
How do you find the gear ratio on a rack and pinion?
Calculating Rack-and-Pinion Gear Ratio Measure the distance from the end of the rack to an arbitrary point, turn the pinion one full revolution and then measure the distance again. The difference between the two is the gear ratio.
What does the 8th digit in a VIN number mean?
Digits in position 4 through 9 make up the Vehicle Description Section (VDS). The fourth through eighth digits describe your vehicle’s model, body type, restraint system, transmission type, and engine code. The ninth digit is the check digit, which is used to detect fraudulent VINs.
How do I know what gear ratio My rear end is?
Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio.
Can you tell gear ratio from Vin?
The vehicle identification number (VIN) is a 17-digit code that is used to identify and track every automobile produced. … The codes on that tag will tell you the gear ratio. The VIN will not give you gear ratios in most cases.
Where do you find the gear ratio?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
