DMS 10.0" 10 RIB Lower Pulley for LSA/LT4 for ATI Balancer

The DMS 10.0" 10 rib balancer pulleys are a great way to increase supercharger RPM resulting in higher airflow and boost levels. These pulleys are CNC machined from 6061 aluminum and anodized for longevity. Designed to fit ATI balancer part numbers 918856 or 918854. The 10.0 can go from mediocre boost up to max effort boost depending on the upper pulley choice. Idler relocation bracket is required. And can be purchased HERE

While this is a 10 rib pulley, it can absolutly be used with a 8 rib setup. Just use the 8 ribs closest to the engine. No negative side effects to worry about.
