Today, HSPN TV, a division of HSPN Networks, released a how-to installation video of the Perrin Performance Lightweight Crank Pulley. According to Perrin, the pulley is crafted from 6061T6 aluminum and weighs in at a meager 1.2lbs, which is 4 lbs lighter than stock. Perrin assures customers that the pulley is not under driven and will not affect the life of your engine. The pulley is simply a redesigned, lighter rendering of the stock crank pulley.

Perrin claims that its pulley achieves power and performance by reducing the rotating mass of the crank assembly. That reduction, according to their website, is effectively the same as removing 100 pounds of weight from your vehicle. Perrin confirms that the pulley will not wear out engine bearings or the oil pump, and will not add any additional vibration or noise.
