This off-highway damper is designed for competition small-block V8s in racing classes which permit the use of production-type balancers. Its nodular iron inertia ring offers an extra margin of reliability at high rpm. High temperature rubber is used between the hub and inertia ring to improve durability. The hub is balanced separately before the damper assembly is balanced as a unit. This heavy-duty damper is ID #4709; its outer ring is marked "MALL." The timing mark is 10º before keyway center line. Technical Notes: Use with chromed timing pointer 809-12341915. See the Chevy Power manual for recommended damper preparation procedures.
