Metco LSA  S/C Pulley


Replace the original supercharger pulley on your CTS-V or ZL1 with one of our precision-made overdrive units to make as much as 5.5 pounds of additional boost for more more horsepower and torque.

Our LSA supercharger pulleys are a three-piece design, utilizing a precision-machined steel pulley hub and an interchangeable aluminum ring and front cover.  The center bore of the pulley hub is sized for the appropriate interference fit and no pinning or drilling is necessary for installation.  The pulley ring and stock-appearing front cover are black-anodized for long lasting surface protection, and the steel pulley hub is nickel-plated (not shown). The interchangeable design allows for easy boost level changes.  Once the pulley hub is installed on the supercharger, the pulley rings (and pulley covers) can be purchased separately and easily changed.

We recommend the installation of the MIP-100V idler pulley (listed elsewhere in this section) on applications using overdrive (smaller) supercharger pulleys.

Note 1:  While the original belt can be re-used with the 2.85" pulley, a shorter supercharger belt is necessary when the 2.40" or 2.50" overdrive supercharger pulley is installed.  The Gates or NAPA 080653 in the premium Greenstripe line, is recommended (0.7" shorter than stock).  If this pulley is installed in conjunction with our MIP-100V idler and the 9.55" pulley ring, a 68.5" belt is recommended. 

Note 2:  The end of the supercharger shaft on the LSA application is not threaded like it is in other applications, so a standard pulley removal and installation tool cannot be used.  The supercharger snout must be removed from the supercharger case and the original pulley must be removed and the new pulley installed using a press or a suitable pulley tool.  No gaskets need to be replaced and generally no lubricant is lost during this procedure.  As part of this changeover, we highly recommend replacing the original snout isolator, which is problematic and prone to make noise.  Our solid isolator is precision-machined from very high grade materials and installs as a direct replacement for the original.       * Fits: 2009 & Newer CTS-V and 2012 & Newer Camaro ZL1


Metco S/C Pulley Rings  (Ring Only)

This listing is for the individual supercharger pulley rings we manufacture for the GM LSA application.  If you already have a Metco Motorsports supercharger pulley kit on your CTS-V or ZL1, these rings will fit the pulley hub on your car.  These pulley rings and covers are precision-machined from billet aluminum and then black-anodized for a long-lasting stealthy appearance. 

This kit includes the pulley ring and matching cover only.  The complete supercharger pulley kits (hub, ring, cover, and fasteners) are listed elsewhere in this section.

Metco S/C Idler Pulley                                            #MIP-100V


This 100mm billet idler pulley is designed to replace the factory idler pulley located directly beneath and to the left of the supercharger pulley.

In CTS-V or ZL1 applications using a smaller than stock supercharger pulley, belt slippage at higher engine speeds can reduce both boost and power.  The larger diameter of this pulley serves to increase belt wrap at the supercharger pulley, as well as increase tension on the supercharger belt.  This pulley is an easy bolt-on solution to troublesome belt slippage.  

This pulley is approximately 4" in diameter and 1.75" wide at the belt surface.  It is compatible with the original 8-rib belt used in the GM LSA application as well as custom applications using a 10-rib belt.

Metco S/C Isolator                                                   #LSA0001


The supercharger isolator is part of the supercharger drive assembly and is located in the supercharger snout.  The original isolator as installed at the factory contains a spring mechanism and is notorious for noise and a short service life.  The spring in the original isolator wears a groove on the supercharger shaft, creating debris that will eventually cause the shaft seal to fail.  Our replacement coupler is precision-machined from a solid piece of high-grade thermoplastic and installs as a direct replacement for the original.  Our coupler is not susceptible to the issues that plague the original unit.

We highly recommend replacing the original isolator with this upgraded unit when an overdrive supercharger is installed on the car.
