Wiseco Toyota 4AG 4V DOME +5.9cc (6506M815 Piston Shelf Stock Kit

Starting with pistons forged from 2618 aluminum, Wiseco builds their Professional Series for serious engine builders tackling demanding performance applications. This set is specifically for the Toyota 4AG 4V engine, featuring an 81.50 mm bore and a dome volume of +5.9cc. This dome shape is designed to work with specific cylinder head configurations to achieve a desired compression ratio, making it a key component for rebuilding or enhancing your engine's top end.

These pistons are fully machined in the USA, with precision ring grooves and features like anti-detonation bands to ensure excellent ring seal and durability under heavy load. They also come with forced pin oiling to keep the wrist pins lubricated, a critical detail for high-performance engines. The ArmorGlide skirt coating is applied to reduce friction and noise, while also providing resistance to seizure, helping your engine run smoother and last longer.

This kit includes everything needed to replace the pistons for a complete set of four. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
