PISTON KIT GM SPEEDWAY 90.00, WOSSNER K8811DE E
This Wossner forged piston kit with a 90.04mm bore (+0.04mm oversize) is 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.
