The MOTOBLUE™ Interchangeable “QC” Blower Pulley System for the Eaton supercharger. The factory Eaton blower pulley is pressed onto the shaft - which makes quick, trackside changes impossible. With the MOTOBLUE™ Interchangeable “QC” Blower Pulley Kit you simply replace the factory blower pulley with a precisely machined hub and attach your choice of pulleys with the 5 Allen head set screws provided.

Running a larger pulley on the street saves fuel, while the 2.75" bumps the boost for a very noticeable performance gain. Consider the time you'll save by installing this system Best of all you don’t pay the high price other manufactures are trying to charge for the same technology.

RPM is proud to announce the introduction of the NEW MOTOBLUE™ GEN X and the Original GEN II BILLET IDLER Pulleys.

Replace your factory hi drag, low quality stamped steel OEM idler pulleys with either the new MOTOBLUE™ GEN X double bearing cnc machined pulley or the original GEN II single bearing cnc machined billet idler pullies.

MOTOBLUE™ GEN X and original GEN II are CNC machined from aircraft quality 6160 billet aluminum. CNC machined for a perfect fit featuring the highest quality “sealed for life” bearings.

The NEW GEN X 90 MM double bearing has been designed specifically to eliminate high RPM wobble common to auxiliary idler pulleys on supercharged applications . The NEW Gen X effectively eliminates any bearing failure caused by supercharger belt side load. This is the same technology that industrial supercharger manufactures use for high load supercharged belt driven systems.
