Hello All, just a quick update... Just passed the 500 mile break in period and so far so good. I will tow my trailer (7000lbs) next week and I will update y'all on how the truck did with the new gears. I didn't smoke the tires yet and I may never...lol, but I did notice better gas mileage and acceleration. So I have attached a link to the YouTube video I put together documenting the install. DISCLAIMER: The video is not an instructional video that shows the step by step instructions. But feel free to ask me questions and I'll try to answer them I wasn't able to video me setting the gear patterns and pinion pre-load on both differentials, but rest assured I did set those to spec. If you're thinking of doing this yourself, be sure you have extra bearings just in case. This is a can do D.I.Y. project...just don't rush the install. With that said, good luck on your projects!
