Designed to be used in S&S cylinder heads for Twin Cam, 4" bore Evolution Big Twin, and Super Sidewinder Plus style S&S engines. Consists of a small valve that opens during starting and allows a portion of the cylinder pressure to escape into the exhaust port of the cylinder head Reduced cylinder pressure makes it easier for the starter to turn the engine When the engine starts, the valve closes and the engine runs normally, with full compression. Electric Compression Releases: Electric compression releases are solenoid operated They automatically open when the starter button is depressed and automatically close when the starter button is released When installed on SSW+ or Twin Cam style S&S engines, S&S electric compression releases require the use of S&S die-cast Twin Cam style rocker covers or similar covers with a central hole or "chimney" The "chimneys" in the rocker covers are required to provide clearance for the solenoids that operate the compression releases Electric compression releases are compatible with S&S rocker boxes for Evolution engines Manual Compression Releases: Manual compression releases are activated by a cable similar to a choke control Before starting, the handle is pulled, which opens the compression releases; when the engine fires, the increased cylinder pressure automatically closes the compression releases Can be used with any style rocker cover Made in USA. |
