Integrated Engineering 188mm Crank Pulley & Damper Upgrade Kit

IE's 188mm overdrive crank pulley creates a dual pulley ratio when combined with your IE 57.5mm supercharger pulley for the Audi supercharged 3.0 TFSI platform. This complete one-piece billet design replaces the crank pulley and engine damper for total reliability.

This 188mm crank pulley is designed to be combined with an IE 57.5mm supercharger pulley (IEBAVJ1C) to upgrade your existing single pulley setup for stage 2 dual pulley tunes.

This complete one-piece pulley replaces both the crank pulley and factory engine damper in one unit. Replacing the engine damper provides increased reliability and protection from a possible faulty stock engine damper that is known to separate, causing costly engine damage.

Weighing in at only 1613 grams, IE engineers have produced a robust pulley while trimming as much fat as possible without risking the structural design. The aluminum construction is 59% lighter than the stock setup, reducing rotating mass, resulting in faster engine revs and less parasitic loss.

This one-piece design delivers significant power and is a vital link that holds your engine and supercharger together. Enjoy the peace of mind knowing your pulley is 100% in-house designed and CNC machined from top-of-the-line sourced aluminum alloy followed by extensive quality-control.

The 6061-T6 aluminum pulley is finished with an attractive black anodized finish. The anodizing process offers superior protection against corrosion while retaining the proper installation clearances. After applying the coating, the alignment marks, part number, and logo are laser etched to guarantee long life and a fantastic look.
