Different Types of Piston Coatings–Build your own Pistons !<br />
1. Thermal barrier coating “Blast Off Bronze”<br />
• Reflects heat into the combustion chamber<br />
• Extends piston life by decreasing the rate of thermal transfer<br />
• Increases exhaust gas velocity<br />
• Greatly improves scavenging potential<br />
• Recommended for any performance application<br />

2. Piston side-skirt and under-crown coating<br />
• Better lubrication<br />
• Anti- Friction and Anti-wear properties<br />
• Reduce the chance of scuffing on dry start ups<br />
• Recommended for any performance application<br />
3. Hard Anodized Coating<br />
• Provides a thermal barrier and increases both corrosion – resistance<br />
and wear-resistance<br />
• Deters piston rings from Micro-welding themselves to the ring grooves<br />
• Resists high cylinder temperature and pressures<br />
• Prevents head soaking through entire pistons<br />
• Recommended for large boost and Nitrous applications<br />

4. Double diamond coating<br />
• This coating is a combination of Hard Anodized and Moly skirt coating<br />
• Give you the best protection from cylinder pressures , high cylinder temperatures<br />
and pre-mature skirt wer<br />
• Reduce friction<br />
• Recommended for large boost and Nitrous applications<br />
