Dayco PB1102N Engine Harmonic Balancer

Dayco PB1102N Premium OEM Replacement Balancer

The Dayco PB1102N engine harmonic balancer is a Premium OEM Replacement Balancer built for a wide range of Chevrolet and GMC trucks, vans, SUVs, and chassis applications from 1982-1993. It uses a hub-weighted counterweight balance and a cast iron outer ring to help maintain crankshaft damping and timing stability in demanding V8 applications.

Product Details

Dayco’s Premium OEM Replacement Balancer line focuses on direct-fit engine vibration control for original-equipment-style service work. The PB1102N harmonic balancer is specified with a hub-weighted design, no crank trigger/exciter plate, and no woodruff key included.
