- M7 Speed 16 percent Overdrive supercharger pulley - M7 Speed standard diameter (stock dampener replacement) Lightweight Overdrive crank pulley - Proper length Micro-V Drive belt for this pulley combinationThe M7 Supercharger Pulley features a 16 percent reduction in diameter and a number of improvements over stock and other aftermarket pulley designs.Our design allows the pulley to be easily positioned deeper onto the supercharger shaft for proper belt alignment and shaft grip from the locking collet. We added shoulders to the outside of the pulley to help prevent the belt from walking off of the pulley surface if you have a weak tensioner or the belt stretches at extreme RPM events. The drive belt grooves are machine to exacting SAE-J1459 specifications. The M7 SC Overdrive Pulley also incorporates an active cooling system that pulls in cool air through the holes in the pulley shoulder, keeping belt temperature down. Made from high quality aircraft grade billet steel and gold zinc plated for corrosion resistance and years of trouble-free performance. Our proprietary taper-loc shaft locking system offers the highest locking force to the supercharger shaft at the lightest weight. The M7 taper-loc is superior to any other design on the market....PERIOD! This high grip taper-lock system offers both ease of installation and slip free supercharger performance. By design, the assembly is 100 percent balanced out of the box.
