How do I know my differential gear ratio?

How do I know my differential gear ratio?

Count the number of teeth on the pinion gear and count the number of teeth on the ring gear. Divide the ring gear teeth number by the number of teeth on the pinion. The result is your gear ratio. Note: you may need to round off the number.

Where is the gear ratio stamped?

If you are not sure about your results when using the wheel rotation method, the number of teeth is stamped on the ring gear. The small number is the pinion-gear tooth count. The large number is the ring-gear tooth count. To find the gear ratio, divide the big number by the little number.

Can you change the gear ratio on a truck?

You can change the axle ratio, and you can do it rather easily. Quite a few members here have gone from one ratio to the next. People with 3.21 and 3.55s are going up to 3.92 and even sometimes 4.10. A lot of the 4×4 trucks you see here with lifts and larger tires have gone with 4.10 or 4.56.

How do I identify my Chevy rear differential?

The rear cover’s shape and the number of bolts are identifying features for GM rear differentials. The round 10-bolt cover with a bulge for the ring gear identifies this axle assembly as an 8.5-inch 10-bolt. The two lugs on the lower case at the 5 and 7 o’clock positions are also identifying features.

Is G80 a locker or limited slip?

Automatic operation During normal driving conditions, the MLocker (G80) functions as a light-bias limited slip differential. When a low-traction situation occurs that causes a wheel speed difference greater than 100 RPM, a flyweight mechanism opens to engage a latching bracket.

What is limited slip differential vs locking differential?

An automatic locking differential can unlock and allow the inside wheel to rotate freely, but only when power is limited. The limited slip differential will allow some slipping between the two side gears, this allows both wheels to get equal traction even though one is spinning faster than the other.

Does a G80 Locker need additive?

The G80 uses Any 75W90 oil with no Additives. A LS diff has to have the additive in it for the clutch packs to function properly. The G80 is a Mechanically Locking Differential that engages when one wheels spins at a certain RPM mechanically locking the differential together.

What does the z71 mean?

The z71 is a code name that Chevy uses to identify the different packages when they make their vehicles. The z71 is designed to be a midsize truck that has an off-road suspension package.

What does G80 mean?

Often referred to as the G80 for its order code, the rear axle locks automatically if one wheel starts to spin, enabling both rear wheels to propel the truck. The added traction lets a 2WD pickup to go places traditionally thought of as 4×4 territory, and further enhances the capability of 4×4 pickups.

Does G80 need friction modifier?

G80 lockers DO NOT require friction modifiers. Mobil 1 synthetic says it has friction modifiers added, and that you can add more if needed.

Does a G80 have clutches?

Utilizing a flyweight mechanism and self-energizing clutch system, the Eaton MLocker (G80) engages in low traction situations when a wheel speed difference of 100 RPM or greater (left-to-right) is detected.

Is a G80 a posi?

Fyi-The G80 is a Eaton Locker and is not a posi. Posi is a term used for Posi-Traction. A term used back in the muscle car era to mean a limited slip differential. A limited slip differentials is normally installed in cars.
