Stop gear oil leaks and protect your drivetrain with the Blue Line GY6 Short-Case Transmission Cover Gasket. Precision die-cut from oil-resistant sealing material, this OEM-equivalent gasket spans the final drive gearbox cover interface on short-case GY6 125cc, 150cc, and 169cc 4-stroke engines. An 8-hole mounting pattern aligned to factory casing tolerances ensures a flush, airtight seal that holds up to thermal expansion, mechanical shear, and modern synthetic gear oils.
Fits short-case GY6 engines only (10-inch rear wheel platforms). Will not fit long-case engines (12�13-inch wheel setups). Always measure your transmission cover length before ordering.
