How do I figure out my rear end gear ratio?
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.
How do I know what gear my axle is?
Rotate the marked tire one revolution while counting how many times the driveshaft rotates. eg, If your driveshaft made 3 3/4 revolutions, that would determine a 3.73 gear ratio. If you get approximately 2 3/4 revolutions, you have a 2.76 gear ratio.
How do I know what gear ratio my f150 has?
Write down the number in the lower left-hand corner of the tag. It will look like “3.23” or “3.50.” This is the gear ratio. If there is an “L” in the number, for instance “3L23,” it is a limited slip differential.
Which RPO code is for gear ratio?
GM RPO Codes – Factory Identification Labels and Interpretation
| RPO Code | Description | Ratio |
|---|---|---|
| GT2 | Axle Rear | 2.29 |
| GT4 | Axle Rear (Dup of 5X1) | 3.73 |
| GT5 | Axle Rear (Dup of GT8) | 4.10 |
| GT7 | Axle Rear | 3.33 |
What is the best gear ratio for acceleration?
In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.
Where do you find the gear ratio on a Toyota 4Runner?
Toyota 4Runner Drive Axle Gear Ratio’s Toyota vehicle model identification comes from the vehicle configuration label which is typically attached to the door latch ed ge on the driver side door or door pillar.
How big are the tires on a Toyota 4Runner?
Here is a table of ring and pinion sizes for various gear ratios in the Toyota 8″ differential: (typical axle ratios for manual transmission equipped trucks, 28″ stock tires) . .
What is the Axle code on a Toyota 4Runner?
The first position of the Axle Code is a letter which identifies the diameter of the ring gear. Toyota trucks and 4Runners have always used the 7.5″ and 8″ diameters, but the others are listed here for completeness.
How many revolutions does a Toyota 4Runner have?
For better accuracy, you can use say 10 (or 20) revolutions and then divide your drive shaft revolutions to get the gear ratio.
