Product Details

Dayco Street Performance Balancer parts are aimed at street-driven engines that need stable harmonic control and accurate timing reference without unnecessary add-ons. The PB1019ST is a direct-fit style engine harmonic balancer for a range of Chevrolet Bel Air, Camaro, Caprice, C10 Suburban, C20 Suburban, El Camino, Impala, K10 Suburban, K20 Suburban, Malibu, Monte Carlo, Nova, and Corvette applications listed below. If you are searching for a Dayco PB1019ST harmonic balancer for a 1970 Chevrolet Camaro or a 1972 Chevrolet Monte Carlo, this part number is the correct reference to verify against your engine build.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Engine vibration caused by a worn or damaged harmonic balancer
  • Timing mark visibility issues during ignition setup
  • Crankshaft damping concerns on street performance engines
  • Cracked, slipping, or deteriorated balancer components
  • Fitment needs for Chevrolet V8 street applications using a neutral-balance balancer

Installation Notes and Tips

Verify crank bore, nose diameter, bolt-hole pattern, and overall diameter before installation. The PB1019ST does not include hardware, installation instructions, a crank trigger/exciter plate, or a woodruff key, so confirm your engine’s required components are already on hand. Because fitment varies by year, engine package, and performance option, match the balancer to the exact vehicle listing and engine configuration before assembly. For example, this Dayco PB1019ST is listed for 1970 Chevrolet Camaro, 1972 Chevrolet Monte Carlo, and 1971 Chevrolet Caprice applications, along with additional Chevrolet passenger car and truck models shown in the fitment data.

Quality Assurance

Dayco manufactures the Street Performance Balancer line for engine applications that require consistent harmonic control and timing reference. The PB1019ST uses a cast iron outer ring and neutral balance configuration to support proper engine setup on listed Chevrolet applications.
