Manley Performance Turbo Tuff Series Crankshaft 79mm Subaru EJ25 2004+ STI / 2006-2014

At the heart of a fully built engine is a strong crankshaft. The Manley Performance Turbo Tuff Series 79mm Billet Crankshaft will be the key foundation for those of you who demand the best in terms of strong internal components built to sustain high boost and high power levels. This crankshaft features 4340 billet construction and has endured a multi-step heat-treating process where the counterweights have been knife-edged to reduce the rotational mass. This will help promote faster revs with improved engine response. It has been balanced and ready to be assembled with the rest of your blue-printed build.

This crankshaft is the result of careful and methodical manufacturing processes and takes your typical high-power engine build to another level. For the most demanding of engine builds, the Manley Performance Turbo Tuff Series 79mm Billet Crankshaft will certainly perform and deliver satisfying results, power, and reliability.
