Underdrive Race Performance
All Powerbond Underdrive balancers are manufactured from forged Steel have pressure bonded rubber with a circlip to encapsulate the outer ring and have the same characteristics as the Powerbond Race series of harmonic balancers. Underdriving a harmonic balancer or making it smaller in diameter slows down the accessories speed reducing parasitic power losses from driving the alternator, air conditioning, water pump and power steering. By reducing the drive belt speed less power is used to run these accessories which will give you more HP, improve fuel economy and better throttle response. Powerbond underdrive balancers are available in a range of sizes and also in kits with everything required to make the change
