If you install the reverse module, be shure to lube the gears and the coupler bushing that goes through the housing. Think about changing the shock oil, the factory oil works but is rather thin and the suspension is pretty mushy. Use a little thread locker on the wheel nuts, they like to loosen up. Install a good air filter like the Motor Saver and an in-line fuel filter. A non esential touch is to put a piece of plastic tubing over the pipe and clamp with a small hose clamp, extend the exhaust down to the bottom of the chassis side plate. This helps keep some of the oils and fuel from messing everything up along the side of the truck.
Most important is to be paitent and do the engine breakin slowly and carefully. It is boring and you want to just go but taking you time will give you new engine more life and better performance.And lastly, keep the Savage away from moving full size vehicles, it cannot win! Enjoy.
