The PERRIN Lightweight Crank Pulley lightens up your rotating engine parts to free up power, a true weight savings that can be felt with every blip of the gas pedal.

Decreases Rotational Mass

The PERRIN Performance Crank Pulley weighs just 1.2 lbs, which is 3.7 pounds lighter than the stock OEM crank pulley. This reduction in weight from the crank shaft is equal to removing more than 100 lbs of vehicle weight! Throttle response, horsepower and torque are all increased with this easy to install part.


Designed to look mean and fast, the PERRIN Crank Pulley has precision machined grooves which tightly sync with all OEM and aftermarket belts.


The PERRIN crank pulley is machined from 6061T6 billet aluminum, anodized black and laser etched for increased belt life and a precision fit.
