Product Description

PROUDLY MADE IN THE USA!

Introducing the JHM HD Lightweight Crank Pulley for the 3.0T FSI!!!

NOTE:If you are looking for more performance out of your supercharger but still looking to address the issue of your OEM crank pulley separating, check out our JHM Overdrive Crank Pulley found in this same section. Our Overdrive Pulley replaces your OEM crank pulley, drops the overall weight of your 3.0T's rotating assembly, and upgrades you to stage 2 pulley ratios - all without changing the pulley on your supercharger!

JHM has been making Lightweight Crank Pulleys for Audis since early 2009. We developed our first Lightweight Pulley for the B6-B7 S4 then came the B7-RS4 Lightweight Crank Pulley. That was followed by the 6-rib pulley systems we developed for our B6-B7 S4 and RS4 Supercharger Kits. After the release of the Supercharger Kits, we came out with a Lightweight Crank Pulley for the B8-S5 4.2L, then the 2.7T, the 3.0L V6, and the 2.0T FSI. We've also developed a 6-Rib Pulley Upgrade Kit for B6-B7 S4s and RS4s that aren't supercharged. Following the success of our Lightweight Crank Pulleys and after hearing of several pulley failures on the 3.0T FSI, we decided to make another JHM solution for a failure prone Audi part: the JHM "HD" Lightweight Crank Pulley for the 3.0T FSI engine.

WHY THE JHM "HD" LIGHTWEIGHT CRANK PULLEY? The OEM 3.0T Crank Pulley is actually two pieces connected by a rubber isolator. The center hub or inner piece bolts to the crank which is joined to the outer by the rubber isolator. We have seen several failures where the inner portion of the pulley separates from the outer at the rubber isolator connection. This leads to a major belt failure and can cause serious damage to the radiator, radiator fans, accessories, and other pieces behind the core support.

The JHM "HD" Lightweight Crank Pulley eliminates the two piece design and rubber isolator found in the stock crank pulley while also reducing the mass of the motor's rotating assembly. Converting to a single piece, solid crank pulley without the rubber isolator will prevent separation of the crank pulley and damage to your motor and/or accessories while reducing the rotating mass of the engine's rotating assembly will also free up horsepower. Our JHM "HD" Lightweight Crank Pulley is anodized black to look stock and blend in.

SPECIFICATIONS:
- OEM 3.0T Crank Pulley Weight: 8.57 to 8.62 pounds
- JHM "HD" Lightweight Crank Pulley Weight: 4.25 pounds
That's a weight reduction of over 50%!!!

PARTS INCLUDED:
- 1x JHM "HD" Lightweight Crank Pulley
- 8x 8mm x 1.25 Allen Bolts

INSTALLATION NOTES:
Our JHM "HD" Lightweight Crank Pulley installs just like your OEM pulley. So, just like you must do with the OEM pulley, make sure that the offset bolt hole on the JHM Crank Pulley matches up to the offset hole on the crank. Then, torque all supplied crank pulley bolts to 20 ft-lbs in a star pattern. We also recommend using Loctite.
