Increase your 2009-2013 ZR1 Corvette's performance with a 2.38" supercharger pulley specifically designed for the LS9 engine. The 2.38" pulley is designed to increase your supercharger's drive by 32% while increasing RPM to 20,300 - without changing the harmonic balancer. The result is 6-10lbs of additional boost!

The 10-bolt attachment is designed to be used with Lingenfelter's hub assembly for quick and easy pulley changes. Hub assembly (Zip # PM-659) must be purchased separately. Use in combination with a 76mm idler pulley (Zip # PM-660) and an 82.5" serpentine belt (Zip # PM-661). No Discount.

Note:Custom PCM programming is required for this pulley application. Do not attempt to run your LS9 Corvette without a knowledgeable calibrator to recalibrate the PCM.
