• Electra-coated for superior strength and wear resistance. The coating creates a surface nearly as hard as diamonds, eliminating micro-welding of the piston rings to the grooves and prevents galling in the pin bore. S ince the domes are Electra coated, there is additional protection against erosion from detonation. The piston also stays cooler since the coating helps re ect heat into the combustion chamber. • Lubrication holes on the four corners for extra protection (six per side) Polaris 800 CFI Wiseco Durability Kits 2008-2017 Kit includes: forged pistons, rings, pins & clips, .250” aluminum spacer plate, base gasket, top end bearings, longer dowel pins and longer cylinder head bolts. • Custom engineered taller pistons.
