Harmonic balancers are a vital part of a passenger vehicle engine. A high-quality balancer will protect an engine from damaging vibrations produced by the crankshaft leading to potentially costly repairs being needed. Without a harmonic balancer there is a large risk serpentine belts such as idler belts way be thrown off track, or even then crankshaft cracking and becoming unusable. These repairs can be incredible costly and are avoidable with the correct part. Harmonic Balancers allow the engine to produce more power and will also extend the life of engine.

Bravway is proud to stock Dayco Powerbond OEM replacement balancers as they are leaders in replacement engine parts, always meeting OE standards. Dayco Powerbond harmonic balancers offer engine repairers the engine repairers the option of a totally new assembly. They are available for a large range of popular passenger vehicles as well as some commercial vehicles and 4WD applications.

Powerbond Harmonic balancer hubs feature high strength and tough SG Iron AS1831-400-12/SAE J434D4512 (also known as nodular iron) for maximum strength. This is the same material used in most crank shafts and has much greater crack resistance. The crank bore size tolerances for Powerbond OEM balancers are tight (±0.015mm) to ensure the harmonic balancer fits the full range of OEM crank shafts to avoids a loose fit. All thread holes are set to the OEM thread size.

Cheap harmonic balancers are usually manufactured from weak, brittle “grey” iron to try and save money, however grey cast iron is prone to cracking resulting in irreparable damage. Most OEM replacement balancers use press inserted dampening rubber which can be prone to spinning and dislocation in high torque and serpentine belt applications. Harmonic balancers that use hot, pressure bonded dampening rubber can withstand much greater torque.
