WORKS ENGINEERING U.S.A Harden Lightweight Crankshaft Pulley is different with others Aluminum crank pulley. It is using T7 Aluminum and over-coating a harden layer. This harden effect will protect the pulley and become wear-resisting. The latest technology that we can let the harden effect to become colored. NEW Diamond coat will last longer than Golden Harden more then 50% - 70%.

Feature:

-BHP & Torque gains across entire RPM range
-Forged
-CAD designed & CNC
-Balanced and heated treated to T7
-Hard anodized in Titanium colour It is smaller in diameter and 50% lighter than the OEM pulleys they replaced, hence maximize the reduction in weight on the crank.
-This reduction in weight reduces the moment of inertia allowing your engine to respond faster to throttle inputs and perform better at all RPMs.
-Material: T7 Aluminum Billet
-Increase 10% - 25% Horse Power
-Fuel Saving: 10% - 20%
-Weight Compare to Original Crank Pulley: 60% - 90% Lighter
-Performance and Reliability Guaranteed
