( Brand: Wossner ), ( Manufacturer Part Number: K7021DA-2 ), ( Part Type: Piston ), ( Make: Ski-doo )
The Wossner K7021DA-2 piston kit is a high-performance upgrade for engines with a standard bore size of 71.86mm and a stroke of 72.00mm. This piston kit is designed for applications with the part number 0910-6336 and is manufactured by the renowned German piston producer, Wossner.
The Wossner K7021DA-2 pistons are made from a forged aluminium alloy, ensuring exceptional strength, durability, and reliability. They feature a dome shape and a dish diameter of 21mm, providing ideal combustion chamber geometry for optimal engine performance. The piston crown is finished with a diamond-like carbon (DLC) coating which reduces friction and increases wear resistance. Moreover, this coating minimizes the risk of detonation, making it a popular choice among high-performance and racing enginebuilders.
The piston skirts of the Wossner K7021DA-2 pistons are completely recipient groove cut which facilitates easy ring adjuster installation and ensures a proper seal between the piston and cylinder wall. The pistons also feature a second oil squirter boss to distribute engine oil evenly across the piston skirt and the piston pin bore to keep it lubricated, preventing premature wear.
Additionally, the piston pins are made from chrome molybdenum steel, ensuring superior strength and durability. They are phosphate-coated to promote piston-to-pin interface bonding, minimizing piston slap, and improving engine performance. The piston pin bushings are of high-quality carbon fibre, reducing weight and optimizing power output while enhancing performance and longevity.
Each piston is individually balanced to meet OEM specifications to ensure proper engine balance, minimizing vibration, and noise. Lastly, the piston kit includes piston rings, piston ring clips, and ring end gaps, allowing for a simple and direct installation process. Overall, the Wossner K7021DA-2 piston kit is a high-performance, reliable, and durable solution for improved engine performance and longevity.
