S&S Compression Release Kit

If you built a big monster of a motor, you want it to destroy the pavement, not your starter. S&S Cycle's compression release system eliminates high compression starting problems. Designed exclusively for S&S cylinder heads, the compression release system consists of a small valve that opens during starting and allows a portion of the cylinder pressure to escape into the exhaust port. The reduced cylinder pressure makes it easier for the starter to turn the engine.

Features:

  • Available in electric or manual styles for S&S heads that accept compression releases
  • Electric compression releases open when you press the start button and close when the button is released
  • Manual compression releases are opened manually and close when the motor starts
  • Kits include the required parts for installation
  • Thread pitch is 10mm x 1.0mm
  • Made in the USA
