I was checking prices on parts for my gear swap and was wondering exactly what i need in the installation kit. They make like three different kits for one set of gears with three different prices. Obviously the higher priced ones have more stuff, just didnt want to buy stuff I didnt need.

 

You need the Master Install Kit.

A brand new truck can get away with just the basic install kit.



However, your truck probably has at least 30,000 miles right? Better to go ahead and replace all of the seals, bearing, shims while you are in there...than just 1/2 *** it, then be digging back into there to fix something else shortly thereafter.
