This part cross-references Pioneer Automotive Industries DA-3601 for the same application. ATP Parts 102001 is also referenced by aftermarket numbers including 309190A and 594135.

What It Helps Address

Installation Notes and Tips

Verify crankshaft diameter, keyway fit, pulley groove count, and overall depth before installation. Confirm the balancer matches the engine’s original solid-style configuration and belt layout.
