Collection: seal primers

The primary drive is the system where engine power first meets the transmission – and this meeting can only be clean and trouble-free if the seals are perfectly in place. The primary drive seals ensure that oil stays inside the primary case while keeping out dirt and dust. This seems like a simple task, yet it is critical: an old or damaged primary cover gasket can lead to oil leaks, which are not only messy and unpleasant but can also, in the long run, jeopardize the operation of the chain or belt and the clutch if the oil level drops. Our selection includes primary drive seals for Harley-Davidson, Indian, and metric motorcycles, from OEM-spec primary cover gaskets to complete gasket kits that include all necessary components for a full primary drive overhaul. Paper-based, rubberized, and more durable, heat-resistant seals are also available, depending on the engine type and usage. Quality seals ensure a precise fit and leak-free sealing, so that the primary drive operates reliably and cleanly for a long time. Whether you need a replacement due to opening the primary cover or a complete primary drive overhaul, you will find the seal that perfectly fits your motorcycle and reliably keeps the oil in place.
