This Perrin crank pulley is a game - changer for your Subaru. It fits multiple models including the 2002 - 2014 WRX, 2004 - 2021 STI, 2005 - 2009 Legacy GT, 2005 - 2009 Outback XT, and 2004 - 2013 Forester XT. Designed for vehicles without AC, it cuts down the engine's rotational mass, enabling faster revs, better throttle response, and a significant performance boost. The anodized black finish with a white PERRIN logo looks great. Weighing just 1.0 lbs, it's 4 lbs lighter than the stock OEM pulley, which is equivalent to removing over 100 lbs of vehicle weight. Machined from 6061 T6 billet aluminum, it has precision grooves that fit all OEM and aftermarket belts perfectly.


Using this Perrin crank pulley is easy. First, make sure your vehicle is one of the compatible models and doesn't have AC. Then, carefully remove the old pulley and install the new one following the standard installation procedures. When it comes to maintenance, keep it clean from dirt and debris. Regularly check for any signs of wear and tear, like loose grooves or damage to the anodized finish. If you notice any issues, replace the pulley promptly. Also, make sure to keep it dry to prevent rust. That's all you need to do to keep your engine running smoothly with this high - performance pulley.
