This is the modification that started it all. We reshape the sitting area of the stock factory foam to disperse your weight better over it. This will help with tailbone pressure and hot spots. We can narrow the thigh area and reshape it so it gives your legs a straighter shot to the ground which will help with better footing. We do not replace any foam with this modification it is strictly reshaping the seat's original foam for better comfort. The factory seat cover is re-used with this modification.
