These pulleys Look and perform great! If you're running a small supercharger pulley to generate much higher boost you may see boost fluctuation at high RPM. This is generally caused by belt slip.

This can be reduced / eliminated by increasing the number of ribs from 6 to 8 on the supercharger pulley. This will also require an 8-rib supercharger pulley and harmonic balancer. Smoothflow Pulleys is proud to offer billet aluminum. 8-rib supercharger idler sets for the L67! These are for those of you who are running smaller pulleys and need some extra belt contact to reduce belt slip.

The pulleys are machined from billet T6-6061 aluminum. The bearings are better than OEM rated at up to 30,000 RPM which should mean years of trouble free service. If a bearing should happen to fail they're easy to replace by removing the button head screws which retain them.

This way you won't need to replace the entire pulley like has to be done with the stock idlers. These pulleys also provide significant weight savings versus the steel 8-rib pulleys offered elsewhere. This is a great mod for your supercharged L67 or L32 to make MORE POWER!!
