Unlock superior off-road performance with our Crawl Ratio Calculator. Precisely determine your vehicle's gearing for maximum control and climbing ability on challenging trails. Optimizing your crawl ratio is crucial for rock crawling and technical driving, ensuring you have the low-speed torque needed for ultimate traction and maneuverability.
Formula:
The Crawl Ratio is determined by multiplying the Transmission 1st Gear Ratio, the Transfer Case Low Range Ratio, and the Axle Gear Ratio (differential ratio). A higher crawl ratio provides more torque multiplication for slower, more controlled wheel speed at low RPMs, ideal for off-roading.
Formula:
Crawl Ratio = Transmission 1st Gear Ratio × Transfer Case Low Range Ratio × Axle Gear Ratio
