Side Cover Gasket - Falcon

The Side Cover Gasket – Falcon by Winters is a precision composite seal engineered for the Winters Falcon transmission, one of the most respected heavy-duty gearboxes in high-performance automotive applications. This gasket prevents fluid seepage at the side cover junction, a critical area where internal transmission pressure meets external elements. Whether you're rebuilding a vintage race transmission or maintaining a rock-crawling 4x4, the integrity of this gasket directly impacts transmission longevity and prevents costly fluid loss that can lead to catastrophic gear damage.

Winters designed this side cover gasket with composite material construction, which provides superior resistance to transmission fluid degradation and thermal cycling compared to standard paper gaskets. The composite formulation maintains elasticity across the operating temperature range of modern transmissions while resisting the corrosive effects of ATF and synthetic fluids. At just 0.01 lbs, the gasket's minimal thickness (0.3 inches) ensures proper fit without requiring shimming, and the compact envelope (5.45 x 5.8 inches) fits snugly within the Falcon's side cover pocket for a reliable seal that won't creep or deteriorate under load.

Mechanics and transmission builders trust Winters Falcon gaskets because they eliminate the need for multiple replacement cycles—critical when your build is race-bound or off-road ready. Installation is straightforward: clean the side cover mating surface, position the gasket, and torque the cover per Winters specifications. This gasket is sold individually, so verify your transmission model requires only one side cover gasket before ordering. Fits all Winters Falcon transmissions that use composite sealing at the side cover interface.
