Fel-Pro Differential Carrier Gasket
About Fel-Pro: Over a Century of Engine Sealing Excellence
Few names carry as much weight in the engine repair world as Fel-Pro. Founded in 1918 in Chicago, the brand has spent more than a century doing one thing exceptionally well: engineering gaskets and sealing solutions that hold up under the punishing demands of real-world engine repair. From a small warehouse on Chicago's streets to a vertically integrated, million-square-foot manufacturing complex in Skokie, Illinois, Fel-Pro has grown into the industry's most recognized gasket brand — earning its hard-won title of The Gaskets Professionals Trust™.
What separates Fel-Pro from the competition isn't just longevity — it's philosophy. While other gasket manufacturers design products for ideal conditions, Fel-Pro engineers its sealing solutions specifically for the repair environment, where engine surfaces are rarely perfect. Cylinder heads warp, oil pans pit, and surfaces score over years of thermal cycling. Fel-Pro's team of dedicated engineers designs every product to accommodate those imperfections, using application-specific materials, proprietary coatings, and innovative construction techniques that create reliable, leak-free seals even on compromised surfaces.
Flagship Technologies That Define the Brand
Fel-Pro's product portfolio is anchored by several breakthrough technologies that have set industry standards. The brand's iconic PermaTorque® MLS (Multi-Layer Steel) head gaskets feature LaserWeld™ Stopper Layer technology and a NextGen coating designed to accommodate surface finishes as rough as 80 Ra — a critical advantage when working with aged engine castings. Their PermaDryPlus® gaskets combine proprietary molded rubber on a rigid carrier to deliver superior sealing performance on notoriously leaky applications, and newer SpeedFit technology even eliminates the need for RTV sealant on select applications, reducing installation error and mess.
Whether you're a professional technician rebuilding a customer's daily driver, an engine builder prepping a race motor, or a weekend mechanic tackling a head gasket job in your own garage, Fel-Pro has a solution engineered for your specific application. The brand's catalog spans engine gasket sets covering everything from full overhaul kits to conversion and head sets, as well as individual cylinder head gasket sets built with advanced MLS technology for today's lightweight, high-temperature engine designs.
Designed, Tested, and Built in the USA
Fel-Pro's commitment to quality is backed by a rigorous development process that includes on-vehicle fit checks, road testing in the brand's Field Test Garage, and validation by Fel-Pro engineers before any product reaches the market. The Skokie facility — home to engineering, product management, manufacturing, and distribution under one roof — produces hundreds of thousands of gaskets daily, with complete, vehicle-specific sealing repair sets shipped to technicians and enthusiasts across North America. That tight integration between R&D and manufacturing means quality is built in from day one, not inspected in at the end.
Today, Fel-Pro is a brand within DRiV (formerly Federal-Mogul Motorparts), giving it access to world-class manufacturing resources and a global engineering network — while maintaining the U.S.-based expertise and application-specific focus that made it famous. With a catalog of over 8,000 SKUs spanning passenger cars, light and medium-duty trucks, performance engines, and marine applications, Fel-Pro remains the definitive choice for anyone who demands a seal they can count on.
