Speed Pro Hypereutectic Pistons for Chevy

Speed Pro pistons: Cast Hyperuetectic Pistons Sealed Power / Speed Pro pistons, is the premier brand of replacement engine parts for automotive, performance and a wide range of other applications. Sealed Power replacement pistons are manufactured from exclusive aluminum alloys matched to the engines’ performance requirements. Proprietary casting, machining techniques and quality control procedures ensure unsurpassed reliability and service

• Optimized metallurgy allows operation with standard ring end gaps and conventional ring land locations
• Speed Pro pistons are Highly resistant to scuffing
• Speed Pro pistons are the Ideal choice for street performance applications
• Most Feature DUROSHIELD^® anti-friction skirt coating

Speed Pro Pistons DUROSHIELD^® skirt coating dramatically reduces friction and related scuffing without the need to adjust wall clearance. The result is enhanced ring seal, increased horsepower and extended piston life.

 Speed-Pro’s hypereutectic pistons operate perfectly with standard ring end gaps and have conventional ring land locations. When compared to traditional cast pistons, which are not designed for performance use, the hypereutectics are significantly stronger, particularly in the highly loaded ring land, skirt and pin bore areas. Speed-Pro’s FM244 Alloy contains 16.5 percent silicon and has excellent tensile and fatigue strength. This material’s improved thermal characteristics, its greater hardness and the increased resistance to scuffing permit tight bore clearances which help minimize noise on cold engine start up. This quiet operation, along with a lower cost are the primary advantages over a comparable forged piston. These pistons are an excellent choice for street performance, “claimer” oval track engines and bracket racing use. Speed Pro pistons will also work well in moderate supercharged applications and are suitable for towing and marine use
