Since we were increasing the tire size, I also needed some better gearing, but tearing into both differentials was way out of my budget. I talked to the 'Zuki experts at Calmini and decided on their 5.14:1 low gearset for the transfer case. Having a super-low gear is great for off-road use, but the bonus is that this setup also lowers the high-range gearing by 18.3 percent. This effectively reduces the stock ring-and-pinion from 3.73 to 4.41, plenty for 30- to 32-inch tires. Tech Editor Dave Kennedy loves transfer cases, so I volunteered him to do this job. He had never seen a transfer case as small as the one in Fredurai, but he quickly had it torn apart.
