How To Choose The Correct Rear Gear Ratio | JEGS
2023年3月17日 · There are three elements involved in determining the best gear ratio: engine rpms, vehicle speed, and tire diameter. Below is a gear ratio chart showing what your engine RPMs would be at 65 MPH based on your tire diameter and differential gear ratio in third gear (1:1 transmission ratio).

How To Select Proper Rear-End / Differential Gear Ratio
The proper rear-end gear ratio can be selected using the following simple formulas whether using a direct-drive (1to1) or overdrive (usually 30%) transmission. FIGURING TIRE DIAMETER (Height) FORMULA: Tire Size / 25.4 x Aspect Ratio x 2 …
Understanding Rear Gear Ratios | Ecklers
The rearend gear ratio refers to the relationship between the driven gear (ring) and the drive gear (pinion), and is easily calculated by dividing the ring gear tooth count by the drive gear tooth count. For example, if the ring gear has 41 teeth and the drive gear has 10 teeth, the correct gear ratio would be 4.10:1.

What Is Rear End Gear Ratio and How Is It Calculated?
Rear end gear ratios can be boiled down to one statement: higher ratios – i.e., with lower numerical value – give better acceleration/torque and lower ratios yield to better fuel economy and higher top speeds.
