SPEED INC. SOLID ISOLATOR - LSA/LS9 - IZMLSA0001
SPEED INC. SOLID ISOLATOR - LSA/LS9 - IZMLSA0001Our replacement coupler is precision-machined from a solid piece of high-grade Delrin and installs as a direct replacement for the original. This unit directly replaces the problematic spring loaded factory version. We highly recommend replacing the original isolator with this upgraded unit when an overdrive supercharger pulley is installed on the car.
