ATP 102042

ATP 102042 is an engine harmonic balancer for selected internally balanced Chevrolet 5.7 / 350 V8 engines. Its OE-replacement design uses an inertia ring and elastomer layer to reduce crankshaft torsional vibration and provide the crank-pulley mounting surface.

Application / fitment

This balancer is cataloged for a broad range of selected Chevrolet and GMC 5.7 / 350 applications, from classic Camaro, Corvette, Chevelle, Impala, and Nova models to C/K pickups, Suburban, Blazer, and G-Series vans. Coverage also includes selected Isuzu NPR chassis using the GM L31 5.7-liter engine.

• engine: Chevrolet 5.7 / 350 V8
• engine balance: internal
• nominal outside diameter: 8.000" / 203.20 mm
• crank-pulley bolt holes: 3
• degree markings: none

Compare diameter, offset, TDC-mark position, and the three-hole pulley pattern with the original balancer. Install it with the correct balancer installation tool; do not hammer it onto the crankshaft or pull it on using only the crank bolt.
