Perrin Lightweight Performance Crank Pulley for Subaru Crosstrek

Upgrading your crank pulley is a quick easy way to gain more engine response, reliability and power. The OEM crank pulley on most vehicles is heavy, unsightly and can be prone to failure. Perrin addresses all of these issues with this high performance lightweight aluminum crank pulley. By reducing rotational mass there is less parasitic drag on the engine, which leads to more power and response (easier revs). The pulley weight has been optimized to provide the perfect performance gain, without triggering false misfire CELs. To address reliability Perrin machines the pulley out of solid 6061 T6 aluminum and eliminated the rubber ring that is often the cause of pulley separation on OEM designs. Replacing the heavier OEM Crank pulley is a great starting point for newcomers and a great way to squeeze a bit more power out of those engines with heavy mods.

Key Features:

• Lightweight design provides better engine response, acceleration, and more power.
• Factory fit for an clean and painless install.
• Weight optimized to prevent false CELs.
• Precision balanced and CNC machined from 6061 T6 aluminum.
• Available in anodized red or black.
