    Enginetech Pistons are manufactured from Cast and Hyper-Eutectic aluminum and then machined to produce a unique diamond finish, all to exacting skirt tolerances. These pistons utilize aluminum alloy high in silicon for GREATER STRENGTH, HEAT DISPERSION, and SEIZURE RESISTANCE.  These Pistons have improved groove wear and resist cracking in the crown area where operating temperatures are severe. These pistons have superior A+ size and weight grading and are manufactured with ONLY state-of-the-art materials to match or EXCEED O.E.M. requirements.

    Each set of Engintech Piston Rings are engineered DIRECTLY for the application.  High-grade gray cast iron for normal applications, ductile high-strength iron for heavy-duty and late model high-output engines.  The reverse-twist, tapered face design of the second ring assures oil control in all types of engine operations. The tapered face assures instant seating of the intermediate groove rings. These rings also do a better job of sealing compression and transferring heat from the pistons to the cooling system, which is ESSENTIAL for rebuilding today's lighter, hotter running engines.

    You simply CAN'T buy a better quality Pistons & Piston Rings for any production application, AT ANY PRICE...
