Detailed Description

This Dorman harmonic balancer is built for a wide range of Chevrolet C1500, K1500, Blazer, Tahoe, GMC Yukon, and related truck and van applications. Part number 594-002 is engineered as a direct replacement for the original engine balancer, with the rubber isolator and steel body working together to reduce vibration transfer and maintain dependable crankshaft damping. This part cross-references PowerBond by Dayco PB1046N and SKP SK594002 for the same application.

Compatible With many 1965-1996 Chevrolet and GMC V8 350CID 5.7L applications, this balancer is a practical choice for service on classic trucks, SUVs, vans, and motorhome chassis vehicles where accurate timing reference and vibration control matter.

What It Helps Solve

• Excess engine vibration from a worn or separated balancer
• Timing mark visibility issues during ignition service
• Crankshaft damping problems caused by deteriorated rubber bonding
• Noise or imbalance concerns at the front of the engine
• Replacement needs on aging Chevrolet and GMC V8 platforms

Installation Notes and Tips

• Inspect the crankshaft snout, keyway, and pulley alignment before mounting the new balancer.
• Use the included Woodruff key, bolt, and washer as specified in the service procedure.
• Confirm degree markings are positioned correctly for timing setup after installation.
• Follow the vehicle service manual for torque and alignment specifications.
