I have put together low range only gear reduction and been installing here locally. 21% reduction in low range only, works wonderful with 30" tires while crawling. Is a big improvement with 32's. We are working on another setup, 33% reduction in Low, 12% reduction for Reverse, High range stays stock ratio. Should work great for 32" and larger tires. I will have the first 33% set installed next week for trial. If there is enough interest on here I will sell them as a kit for you to install.
