Review WISECO Piston 474 P2 Motocross

The WiseCo 474-P2 piston is a high-performance aftermarket replacement piston designed specifically for small block Chevrolet engines. This piston is engineered to deliver improved power and durability compared to OEM pistons.

The piston crown is machined from forged 2618-T6 aluminum alloy, ensuring superior strength and rigidity. The crown design features a dish shape with a compressive height of 1.020 inches and a total height of 1.710 inches. The crown also includes a second ring land for use with dual compression rings, enhancing combustion efficiency and reducing friction.

The skirt of the piston is also machined from forged 2618-T6 aluminum alloy and features a full-length, split-ring oil control groove. This design helps to prevent oil from entering the piston ring grooves and ensures optimal piston-to-cylinder wall contact for better sealing and longer engine life.

The piston pin bore is precision-machined to accept a 0.120-inch pin, and the piston pin is held in place by a 0.062-inch thick, chrome-molybdenum steel wrist pin retaining ring. The piston pin bore also includes a 0.040-inch relief to accommodate expansion during engine operation.

The piston is also designed to accommodate aftermarket connecting rods with a 1.940-inch pin-to-center distance. The piston-to-wall clearance is 0.010 inches, providing ample clearance for normal engine operation while minimizing the risk of piston-to-wall contact.

The WiseCo 474-P2 piston is designed to meet or exceed the performance requirements of small block Chevrolet engines and is an excellent choice for high-performance applications. Each piston is meticulously inspected during manufacturing to ensure the highest quality and consistency. With its superior strength, durability, and performance characteristics, the WiseCo 474-P2 piston is the ideal choice for those seeking to maximize the potential of their small block Chevrolet engine.
