The Polaris 800 Dura Kit adds a cylinder spacer to raise the piston height, which in turn, allows taller pistons to be used. These two features, along with running a tighter clearance, will heavily reduce the ability for the pistons to rock inside the cylinder bore and will increase the durability of the Polaris 800 motor.
