Overview

By reducing rotating mass you are reducing the amount of power it takes to rev up the engine, resulting in a faster revving engine. Under drive pullies also reduce the parasitic draw on the engine from accessories by spinning them at a slower speed. We are proud to offer these lightweight under drive aluminum alternator pullies for the 24V VR6 engines. Weighing in at 95 grams, they weigh significantly less than the factory units they replace. They are a direct fit for all 24V VR6 engines. These pullies are made in house on our CNC lathe from 6061 aircraft aluminum, and finished with a gloss clear anodize finish.
