PISTON KIT GM SPEEDWAY 90.00, WOSSNER K8811DE E
Wossner forged piston kit with a 90.04mm bore (+0.04mm oversize) designed for all Speedway applications, including GM Speedway 499cc engines. Precision-forged in Germany, the piston features superior strength and optimal heat transfer capabilities. Its elliptical profile promotes uniform pressure distribution and expansion under thermal load, minimising stress and reducing the risk of piston failure. Features forged construction for maximum strength and performance, engineered for efficient heat dissipation from combustion to cylinder walls, and an elliptical profile that ensures consistent bearing surface under expansion, reducing localised pressure and evenly distributing thrust loads. Manufactured in Germany. Specifications include bore: 90.04mm (+0.04mm Oversize), actual bore: 89.96mm, display volume: 499 cm³, stroke: 78.50mm, clearance: 0.08mm, dome volume: +5.60 cm³, and compression height: 22.00mm. Cross-reference OEM part numbers: 56-W9841.E, 8811DE. Lock part number: CW21. Pin part number: WP074. Ring set part number: 900ADS. Weight: 386 grams.
