Designed to increase supercharger speed safely and efficiently, the TruDrive delivers the rapid boost response, mid-range surge, and top-end power that the 3.0 community has come to expect from high-quality overdrive crank pulleys. Look we didn't reinvent the pulley, we evaluated existing designs and asked how we could make them better. We found areas to add strength, reduce weight, and add sizes that the community needed. \u003c\/p\u003e\n\u003ch3 data-start=\"730\" data-end=\"793\"\u003e\u003cstrong data-start=\"734\" data-end=\"793\"\u003eLightweight Exterior.
