- All our machining is done and designed in house. Our “G3” pistons are designed to have no sharp edges which are the areas heat tends to be concentrated. They are machined smooth in all areas. Steel top ring groove Coated skirts to prevent piston scuffing on the cylinder walls. Plasma coated steel top ring, Ductile Iron second ring, oil ring is two piece design to maintain oil containment. Our coating has been tested and proven to hold up to the intense cylinder heat and pressure. Coating isn’t everything. Preparation of the surface is mandatory for proper retention.
- Choate Engineering pistons are designed with the problems in mind. As do all our products, these pistons help to solve issues of piston failures! The reiterant bowl design is used to increase the temperature in the bowl to lower hydrocarbons. The reverse flow area in the pocket of the piston creates a “hot spot” that can lead to piston failure. After the fatigue of the alloy, the exhaust gasses act as a cutting torch and start from here ending in a crack across the piston in the same axis as the wrist pin. Knowing this we machine the area causing these issues to relieve it from generating these hot spots, and shortening the swell time of the reverse flow area. The polyphen coating used is a thermal barrier coating that resists heat and heat absorption into the piston. Which forces more heat into the cooling system via the piston rings. By keeping the heat in the cylinder instead of the components it not only causes the internals to live longer but also gives more efficiency to the engine. We offer valve reliefs for larger cams, and lower compression ratios for higher boosted engines. This is a great addition for high-performance engines, some race applications, or those that are towing heavy and need peace of mind. We engineer these parts for your success.
