For more information, visit www.P65warnings.ca.gov.This JHM Overdrive Crank Pulley is an alternative for other companies' smaller supercharger pulleys and will require stage 2 software. If you already have a smaller supercharger pulley or you are looking to upgrade your crank pulley without requiring a software change, see our JHM Lightweight Crank Pulley for the 3.0T. However, a current popular modification is to "double up" or run "dual pulleys" which means running a smaller supercharger pulley in conjunction with an overdrive crank pulley. However, following the launch of the JHM Overdrive Pulley has been a flood of other overdrive pulleys on the market that combined with a smaller supercharger pulley will spin the OEM Eaton 1320 Supercharger far outside of the designed efficiency range which can result in a huge loss of reliability and longevity. If you decide to go with a "dual pulley" setup, using the JHM Overdrive Pulley will be your safest bet.
