[Title] Crawl ratio [Description] 
Crawl ratio is calculated by multiplying transmission gears, transfer case (in 4Lo) and axle differentials. The lower the crawl ratio is, the slower a vehicle can “crawl” in first gear and low range. Low crawl ratios mean higher torque available at the wheels, good for climbing steep gradients.
