Here is a side by side comparison of a stock silverado 4×4 chassis and the one I’ve just finished for the Blue Blazes edition one of one. Smoothed and polished bumpers, grill, side steps, front and rear axles/differentials, plus hand painted blackout chassis and drilled exhaust tips. Of course the most notable mod is the custom made rear drive shaft! Old solid block style “shaft” was drilled/cut/removed and ground very smooth so as to not catch the eye. Then two holes were drilled in chassis where the drive line should attach. Stainless steel tubing was cut to length and ends beveled/polished. It was then mounted using brass rod in each end. The tension holds the shaft extremely stable but still was given a drop of epoxy for lasting results.
