A tool designed to determine the appropriate gear ratio for a Jeep vehicle’s axles, given parameters such as tire size, engine RPM, and desired speed. For example, inputting a 35-inch tire size and a target highway RPM might yield a recommended ratio of 4.56:1. This ratio represents the number of times the driveshaft rotates for every rotation of the axle.
Correct axle gearing is crucial for optimizing a Jeep’s performance both on and off-road. A properly selected ratio can improve fuel efficiency at highway speeds, enhance low-end torque for challenging terrain, and prevent strain on the engine and transmission. Historically, determining these ratios involved complex manual calculations. Digital tools streamline this process, enabling quick and accurate determination of ideal gearing for specific modifications and driving conditions.
