Detailed Product Description and Specifications

The Dayco PBU1480SS10 harmonic balancer features a 6-bolt hole design ensuring a secure fit on compatible crankshafts. Its neutral counterweight balance means it does not add or subtract from the engine’s existing balance, maintaining factory specifications. The crank bore measures 1.481 inches (37.60 mm), matching the crankshaft dimensions of select Chevrolet Camaro, Pontiac Firebird, and GTO engines.

This harmonic balancer includes two integrated serpentine pulleys: the first pulley has 4 grooves with an outside diameter of 6.335 inches (160.9 mm), and the second pulley has 6 grooves with an outside diameter of 6.615 inches (168.0 mm). Both pulleys are designed for serpentine belts, supporting accessory drive systems. The steel outer ring adds strength and longevity to the balancer, while the overall width of 3.65 inches (92.7 mm) ensures proper clearance and fitment.
