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.

Installation difficulty: 5
Our technicians have determined that the installation difficulty level of this item is a 5 on a scale of 1-5. Read more about our install ratings here.
Almost no effort. Either snap on or plug and play. Probably no tools involved.
Simple installation with common tools. Probably less than 20 minutes for installation. Easy enough for
anyone who can read and follow instructions. A good first project for someone with no experience. Hard
to mess up.
A little mechanical experience is helpful but not necessary. Possibly a good first project for those with
a little more confidence. Will probably take more time (20-60 minutes) than #2.
Mechanical experience a definite plus. Not a good first project for the inexperienced. Most likely a 2-3
hour job minimum.
Only for the experienced wrench. Most likely requires good tool collection, possibly special tools and
a fair amount of experience. 95% of people will choose to have this installed by Zip or a professional.
