Why are TuffBond® Harmonic Balancers so different?

These premium Harmonic Balancers are manufactured using the unique TuffBond® process.

• Precision CNC machined high tensile alloy steel hub and vibration dampening ring

• special formula dampening elastomer rubber.

• Absorbs more damaging torsional harmonic vibrations

• exclusive Tuffbond elastrometic bonding process creates an intermolecular bond

• Improved vibration dampening

• Increases engine life

• Quicker engine acceleration

• Never requires maintenance or rebuilding - ever!

• Each unit is balanced, painted, and oil seal area is treated with a preservative to prevent rust.

• Lifetime warranty, even for racing use - a world first!

Utilizing the ORIGINAL TuffBond®  elastrometic bonding process
(a similar process to that used by Mercedes and BMW in production of balancers and engine mounts).

Balancers manufactured using traditional dampening materials and assembly methods are prone to breakdown through heat and vibration. 

The twisting forces applied to a balancer
 -  particularly in performance applications - causes spinning and loss of timing accuracy.

Some manufacturers knurl the metal faces exposed to the dampening material in an effort to reduce spinning.
Subjected to constant vibrations, dampening contact problems and, eventually, breakdown of the dampening material results.
