Well, after a long wait, they gears have finally been installed! I and a friend of mine installed them, started at about 9am and finished about 8pm last night, with a couple long breaks in between for parts runs. All I can say is: WOW! I should have done this a long time ago. It is no effort for the truck to stay at higher speeds now. And my takeoff from a standstill is awesome. Plus overdrive, being used again! I totally recommend this upgrade, especially if you are running larger tires. The install went fairly smooth, the front end was harder than the rear. Shimming the front for backlash sucked, because you have to press and unpress bearings to move shims around so everything fits right. That was the time consuming part. But, all in all, it went pretty easily. I also recommend having air tools, makes life easier. And an impact gun that has massive amounts of torque, for doing the new crush sleeves. Anyway, I just thought I would share that.
