  • Sale
  • Regular price $999.00

Internals are an ever-so-crucial component for every high horsepower engine build. Going with quality parts is essential to making power effortlessly and efficiently. JE Pistons w/ upgraded rings are what we have used in every one of our shop and track cars. We have put these to the test and through the ringer - and they passed with flying colors.

We commonly see people choose to step down in compression to a 9.5:1 piston, but in general we recommend maintaining factory compression when building your motor.***

  • Dome/Dish requires no deburring or preparation

  • .866 x 2.250 straight wall carbon steel wrist pin provided.
