About This Product
Put an end to the "ever-present" main drive gear oil leak with "The Cure" seal kit for 4-speed Big Twin transmissions. This kit replaces the inadequate factory spacer with a precision-engineered, two-piece stainless steel spacer and a Viton O-ring. This combination ensures a permanent seal between the spacer and the main drive gear, preventing oil from escaping. It is designed for 1980–1981 Big Twin and FX models, replacing OEM 35070-80. Installation is straightforward and can be performed without disassembling the transmission. It is an essential upgrade for any rider who wants to maintain a clean and efficient classic Harley-Davidson.
