COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop Teflon seal is used. The umbrella seals require no machining, but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

Product Features:

Work with stock guides and 11/32″ valve stem diameter
Valve stem oil seals keep unwanted oil from entering the combustion chamber
Several different types of valve seals are offered

The COMP Cams High Energy Die-Cast Aluminum Roller Rocker Arms are new rocker arms from the valve train leader that have been designed for street and moderate race use. They feature a die-cast body created from aluminum with a needle bearing fulcrum and roller tip. The die-cast, larger than stock body offers the strength properties and light weight of aluminum while the specially engineered fulcrum and roller tip decrease friction and lower oil temperatures, thus improving response and horsepower.

Product Features:

Cost effective aluminum construction provides superior strength to weight ratio
Needle bearing fulcrum and roller tip reduce friction and lower oil temperatures for improved response and horsepower
Durable design increases valve lift while withstanding the rigors of moderate race use
Die-formed aluminum body is larger than stock, and may require modifications to stock valve covers for clearance.
