Cometic MLS Head Gaskets
Cometic MLS head gaskets are constructed from multiple layers of stainless steel for additional strength over traditional gaskets. They contain load-controlled embossments that help conform load distribution across the sealing area, and where applicable, valve pocketing to avoid chamber intrusion. This creates an exceptional seal by requiring less clamp load and resulting in less bore distortion. The stainless-steel outer layers utilize a rubber-binder coating that features high-temperature and chemical-resistant polymers. These gaskets are available for most cylinder heads. As with all Cometic MLS head gaskets, no sealants or re-torque is required when properly installed on prepared surfaces. Get the engine performance you want with an assist from the Cometic MLS head gaskets best suited for your application.

Fel-Pro Differential Cover Gaskets
Vehicles manufactured after 1990 often have differential housings sealed with RTV silicone. Over time, extreme vehicle vibration and even rough roads can cause the RTV bead to break. If the bead breaks and the vehicle loses the axle lube, the transmission gears begin to rub and wear. That's the whining sound that you hear. Unfortunately, it's a repair that needs immediate attention. Fel-Pro offers precut differential replacement gaskets for these applications, so you won't have to worry about applying RTV and waiting for it to set up to seal. These gaskets are available in a variety of materials, thicknesses, and configurations for precise fitment on nearly 70 differential case designs. Order the model recommended for your application—and eliminate the need for messy RTV sealant.
