Pistons That Arrive Already Coated
PolyDyn high performance pistons come with our ceramic piston coating technology already applied, which gives the piston dome real strength and efficiency and adds to the life of the piston.
Why buy them already coated
Ordering a pre-coated piston direct from PolyDyn saves you both time and money against buying a piston, shipping it to us, and waiting for it to come back. If you would rather coat pistons you already own, that is the piston coating service.
We apply special coatings to different piston surfaces: the top, the skirts, the pin bore or the underside. Tell us which surfaces matter for your build.
What the coating does
The coating is scientifically formulated to maintain the same coefficient of expansion as the base metal it is applied to. It protects and insulates to maintain the structural integrity of the piston and reduce potential engine failure.
Because it protects the piston from heat and evenly distributes heat through the combustion chamber, a coated piston allows more efficient flame travel, and more efficient flame travel leads to more power. The heat insulating polymers reduce heat saturation into the piston, which keeps more heat in the combustion chamber and allows more fuel and less timing.
Pair them with pre-coated bearings from the same inventory. Full specifications are on the technical data page.
