This Piston comes with Wiseco's new Armor Plating Coating. Armor Plated wiseco pistons have almost a bronze colored tint to the top of the piston and the wrist pin bore. Wiseco's Armor Plating is an abrasion resistant plating that raises the hardness of the aluminum, increases the durability of the ring grooves, prevents micro-welding of the piston rings, reduces carbon buildup and combats corrosion caused by detonation.Wiseco's most popular pistons now include Armor Plating. Eagle Rod features "Two Piece Forging" and high quality H-BEAM Forged 4340 steel for superior fatigue life. Rod caps are separately forged for the grain to be perpendicular thereby strengthening the connecting rod.
