Billet Aluminum Supercharger Tensioner Pulley Upgrade, Audi Supercharged EA837 3.0T
Billet Aluminum Supercharger Tensioner Pulley, Audi 3.0T
Replace the weak factory pulley with a stronger, more durable solution designed for the demands of the Audi 3.0T platform. This upgraded pulley comes with a pre-installed bearing to provide improved reliability and consistent belt control. Designed as a direct-fit replacement, it works with all 3.0T Supercharged engines.
Factory pulleys are made from plastic, which can become a failure point as mileage, heat cycles, and belt load increase. Over time, the original pulley may crack, distort, or wear in ways that affect performance and dependability. By switching to billet aluminum, you get a more robust component that is better suited to handle long-term use and demanding conditions without the flex or deterioration associated with plastic.
In addition to increased strength, the billet construction helps maintain more consistent belt alignment and tracking. That means a more stable setup, better durability, and added confidence whether the vehicle is stock or sees harder use.
This assembly is available as a stand-alone pulley or an OEM tensioner with a billet aluminum 7-rib pulley.

Supercharger Tensioner Pulley FAQ
Do I need the stand-alone pulley or the OEM tensioner assembly?
If your factory tensioner body is still in good shape, the stand-alone billet pulley is all you need. If you'd rather replace the whole assembly at once, we offer it paired with the Litens 950961A OEM tensioner for a total assembly price of $118.
Why does the factory pulley fail?
The factory pulley is plastic. As mileage, heat cycles, and belt load add up, it can crack, distort, or wear in ways that throw off belt alignment and tracking.
Is this a direct bolt-on, or does it need modification?
It installs in place of the factory tensioner pulley with no modification required.
Will this fit my 3.0T supercharged Audi?
Yes, as long as your engine code is on the Compatible Engine Codes list above - it's a direct fit across the full EA837 3.0T supercharged platform, including a pre-installed bearing.
What's it made from?
CNC-machined 6061 billet aluminum, engineered and manufactured in the USA.
