Fel-Pro Performance Rear Main Seals - Polytetrafluoroethylene, High Vacuum and Fluoroelastomer
Fel-Pro has a variety of specialized crankshaft main seals to handle the unique needs of the professional racing engine builder. Unique materials and design configurations optimize performance under high crankcase vacuum conditions, elevated temperatures and high RPM levels. These seals can be depended upon for leak-free performance.

Rear Main Bearing Seal Construction and Materials
There are three basic types of rear main seal designs - the rope type, the two-piece molded rubber seal, and the one-piece radial seal. In most cases, only one type of seal is applicable because of the way the engine was designed. The same type of seal is used for replacement as was installed as original equipment by the engine manufacturer. The one exception is Fel-Pro Performance part number 2903, which is a two-piece molded rubber design for Buick V6 engines - it replaces the original rope-type seal.

Fel-Pro Performance rear main seals are made of high-grade synthetic rubber material such as polyacrylate, silicone, fluoroelastomer, or polytetrafluoroethylene for the best high-heat and abrasion resistance.

Sealing Engines Which Have Been Align Honed
When Chevrolet 400 small-block V8 race engines are align bored and honed, the original housing bore for the rear main bearing seal is enlarged. In the past, the engine builder had to put a shim behind a conventional seal to fill the enlarged opening. That is no longer necessary with the use of Fel-Pro Performance part number 2909, a rear main bearing seal with an enlarged outside diameter to eliminate shimming. The Fel-Pro Installation Tips (FIT) packed with this set include correct housing and shaft dimensions.
