Product Details

The ATP Parts OE Replacement Balancer line is focused on direct-fit engine service parts that match original function and dimensions. This harmonic balancer uses a hub-and-damping construction to absorb crankshaft vibration, helping protect the front of the engine and keep accessory drive components aligned. ATP Parts 102041 is listed for 1966-1968 Chevrolet Bel Air, Caprice, Impala, Malibu, C10 Suburban, C20 Suburban, K10 Suburban, K20 Suburban, and 1968 GMC G15/G1500 Van and G25/G2500 Van applications with the specified solid balancer configuration.

What It Helps Fix

• Crankshaft vibration at the front of the engine
• Belt misalignment caused by a worn balancer
• Outer pulley movement from deteriorated damping material
• Accessory drive noise related to harmonic imbalance
• Engine damage risk from a failed harmonic balancer

Installation Notes and Tips

Verify the engine uses a solid balancer with a 6.12-inch outer diameter before ordering. Confirm pulley groove count, inside diameter, and mounting-hole layout against the original part. Inspect the crankshaft snout, keyway, and belt alignment during installation, and replace any worn accessory drive components at the same time.

Quality Assurance

ATP Parts OE Replacement Balancers are built to fit and function like the original component, restoring normal engine operation when the factory balancer has deteriorated or failed. Part Number 102041 is engineered for direct replacement use on the listed Chevrolet and GMC applications.
