ONE PULLEY - DUAL PULLEY POWER
This 207mm crank pulley delivers a supercharger ratio similar to a traditional dual pulley setup that uses a combined smaller 57.5mm supercharger pulley with a larger 188mm crank pulley. This pulley allows the use of a dual pulley ECU tune without the need to purchase multiple pulleys and press off/on a new supercharger pulley for a faster and easier installation process.
If you already have a smaller supercharger pulley installed, purchase the 188mm crank pulley part number IEBAVJ7 to go dual pulley.

CRANK PULLEY & DAMPER
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.
LIGHTWEIGHT DESIGN
Weighing in at only 2025 grams, IE engineers have produced a robust pulley while trimming as much fat as possible without risking the structural design. The aluminium construction is 49% lighter than the stock setup, reducing rotating mass, resulting in faster engine revs and less parasitic loss.
MADE IN THE USA
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 aluminium alloy followed by an extensive quality-control process.
QUALITY FINISH
The 6061-T6 aluminium 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.
INSTALLATION
Installing your new pulley is straightforward and hassle-free with the proper tools. Although installation requires using a grinder to remove an unused small metal post from the engine block, the installation is typically easier than press-fitting on a supercharger pulley.
Install time around 2-3 hours

*2016-2018 A6 & A7 CREC 3.0T engines do not have compatible IE software support for 207mm lower crank pulley. IE single pulley CREC tunes safely produce typical dual pulley ratio numbers on this platform. Running 207mm or dual pulley ratio setups may cause supercharger clutch failure on CREC engines and is not recommended. CREC engine is also found in ROW (rest-of-world) markets on some late-model S4 & S5 3.0T as well. CREC engines are easily identified as the supercharger pulley has 4 bolts to attach it to the supercharger instead of a press-fit style.

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.

3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.
