One the most critical components of any engine is the head gasket — which seals the cylinder head to the engine block. AJUSA offers excellent coverage for European and Asian vehicles in the U.S. and Canadian marketplace.
In addition to their already wide range of head gaskets for European and Asian vehicles, AJUSA also offers head gasket sets that include all the required gaskets and seals. For your convenience, the corresponding head bolt set part number is printed on the packaging.
• All parts include torque sequence and spec sheet
• MLS gaskets are coated in Viton to ensure the best possible seal by compensating for irregularities in engine block or cylinder head
• Fiber-Max gaskets are covered in silicone for the best possible seal for cast iron engine blocks and cylinder heads
• Most Fiber-Max head gaskets incorporate one-piece fire ring
With over 100 complete head bolt sets covering over 70 million vehicles in operation today, AJUSA offers one of the widest and deepest head bolt programs on the market. Sets include thread and head bolt lube—a necessity to ensure proper torque reading during installation. AJUSA also offer specialized custom packaging that ensures bolt thread integrity.
Valve cover gaskets and sets are used to seal the valve cover to the cylinder head. Some vehicles require additional components such as spark plug tube seals or small grommets more commonly seen on modern engines. AJUSA makes OE-quality gaskets for a growing number of European and Asian applications, plus sets that include all the needed ancillary parts.
Hydraulic lifters ensure the correct amount of clearance in the valve train of an engine so that it remains quiet and operates correctly. AJUSA hydraulic lifters are all designed to OE specifications and shipped in plastic trays that keep each lifter isolated, oiled, and protected until they are ready to be installed.
These gaskets seal components in the intake and exhaust systems of the vehicle such as the intake manifold, intake plenum, and exhaust manifold to the engine or other components. Like all AJUSA products, these gaskets are OE-quality in fit, form, and even material type. AJUSA offers the most complete coverage for European and Asian vehicles available anywhere.
Silicone sealant is used as a "gasket replacement" when there is no gasket called for between two components by the vehicle manufacturer. Quick-curing Ajusil is often used to seal water pumps, oil pumps, oil pans, and valve covers to the engine — and in some cases, transmission pans to the transmission. It is also designed to work in a wide operating range from -76°F (-60°C) to 572°F (300°C) and be resistant to oil, water, antifreeze, gas, and a wide range of greases.
