Primary To Trans Gaskets

1 products

Our range of primary to trans gaskets for Harley-Davidson covers replacement gaskets that seal the joint between the primary case and the transmission housing on FXR and early FLT/Touring platforms. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks primary to transmission gaskets from Cometic — the long-respected American specialist whose gasket materials are widely used across the Harley-Davidson trade. Fitment covers 1979–1984 FLT/Touring and 1982–1984 FXR, both early Shovelhead-era and Evolution-era platforms where this specific gasket spec applies. The primary-to-transmission joint is a low-pressure but high-frequency leak point, and using the correct material grade ensures proper sealing under heat cycling and engine vibration. Whether you're refreshing an early FXR or restoring a 1980s Touring bike, fitting a fresh gasket during any related service avoids future leaks. Browse the full range below.
