PISTON KIT GM SPEEDWAY 92.00, WOSSNER 8811D200C
Wossner forged piston kit with a 92.00mm bore (+2.02mm oversize) for Speedway applications, including GM Speedway 499cc engines. Made in Germany, it offers outstanding strength and heat management. The elliptical piston design provides even expansion and pressure distribution under thermal load, minimising stress and helping prevent piston failure in high-performance environments. Features include forged construction for superior strength and durability, engineered for efficient heat transfer, an elliptical profile for a consistent bearing surface under thermal expansion, and even thrust load distribution to reduce localised stress. Specifications include bore: 92.00mm (+2.02mm Oversize), actual bore: 91.94mm, display volume: 499 cm³, stroke: 78.50mm, clearance: 0.08mm, dome volume: +5.60 cm³, and compression height: 22.00mm. Part numbers: 56-W9841_200, 8811D200C, Pin Part Number: WP174, Ring Set Part Number: 920ADS-2. Weight: 382 grams.
