The Crawl Ratio Calculator helps drivers and builders evaluate a vehicle’s low-speed torque capability by calculating the combined effect of the transmission’s lowest gear, transfer case low range, and differential ratio. This value is critical for off-road vehicles, rock crawlers, and utility vehicles where precise throttle control and maximum torque at low speeds are required. The calculator also supports reverse calculations, allowing users to solve for any single component when the crawl ratio and remaining drivetrain ratios are known.
