The Wiseco 813m08550 Pro-Lite Piston Kit is a high-performance upgrade for your engine, specifically designed for applications requiring increased power and reliability. This piston kit contains all the necessary components for a complete piston assembly.

The 85.50mm bore size of this piston kit is engineered for optimal combustion efficiency. Each piston is made from Wiseco's proprietary 2618-T6 forged aluminum alloy -- a material renowned for its strength, rigidity, and durability. With a compressive strength exceeding 130,000 psi, these pistons are capable of handling the increased cylinder pressures often encountered in higher-horsepower applications.

The pistons in this kit feature a 5.50mm wrist pin, reducing friction and wear within the engine. The wrist pins are made from heat-treated, nitrided steel, providing excellent fatigue resistance and reducing the likelihood of failure. Additionally, the piston skirts utilize a roller design, which decreases friction and increases piston ring seal.

Another noteworthy feature of this piston kit is its Pro-Lite design, which aims to reduce overall engine weight. By employing lighter pistons, you can expect improved engine response and overall performance. This makes the Pro-Lite piston kit an excellent choice for those seeking more power and agility from their engine.

The dome shape of the piston tops facilitates the smooth transfer of combustion forces, enhancing power output and reducing piston damage. Each piston is also equipped with a 0.030-inch overboring, providing an excellent fit in engines that have already been overbored.

In summary, the Wiseco 813m08550 Pro-Lite 85.50mm 5.50mm 850cc piston kit offers robust performance and enhanced durability. Ideal for high-power applications, it features forged aluminum pistons, nitrided wrist pins, roller skirt design, and a lighter Pro-Lite weight. Upgrade your engine to the exceptional reliability and performance that comes with the Wiseco Pro-Lite piston kit.
