Reduce friction. Control heat. Prevent engine damage.
Pistons operate at the center of combustion, exposed to extreme heat, pressure, and constant movement. Without proper protection, this leads to friction, wear, and performance loss. Our coatings reduce friction, control heat transfer, and protect critical surfaces under demanding conditions.
For two-stroke applications with unique thermal demands, see our two-stroke piston coatings. Pair with wrist pin coatings for complete piston assembly protection.
Reflects heat into combustion, reducing piston temps.
Minimizes scuffing and wear on the cylinder wall.
Better combustion and reduced parasitic loss.
Protects against heat fatigue and premature wear.
Crown Coating (CBC2): A ceramic thermal barrier applied to the piston crown. It reflects combustion heat back into the chamber rather than absorbing it into the piston — improving efficiency and reducing thermal stress.
Skirt Coating (CermaLube / TLML): A low-friction coating on the piston skirt. It reduces contact friction with the cylinder wall, especially during cold starts and high-load conditions where oil film may be minimal.
The combination of both coatings delivers the best results: thermal protection where combustion happens, and friction control where movement occurs.
They reduce friction on the skirt and control heat transfer at the crown — protecting critical surfaces under extreme conditions.
Yes, in a very controlled amount — typically 0.0005"–0.001". They're designed to work within proper clearance specifications.
By reducing friction and improving heat management, coatings help engines operate more efficiently and consistently under load.
No. They benefit both high-performance builds and street engines where durability matters.
When properly applied and maintained, coatings last the life of the piston. They don't peel or flake under normal operation.
