Underdrive Powerbond  Race Performance Balancer Kit

The Dayco POWERBOND Underdrive race series kit brings the advantages of bonded balancers to high revving race and street/race applications where an SFI approved balancer is required.

Every Race Series Dayco POWERBOND balancer features a precision CNC machined AUSI 1045 forged steel hub bonded to an equally strong steel inertia ring. Advanced design means that Race Series balancers are very light for an all steel product. In most cases they are only marginally heavier than the original cast iron balancer and generally much lighter than other all steel balancers on the market.

The steel inertia ring of the Race Series models is positively protected against forward and backward movement and has the assurance of bonded rubber to eliminate spinning.

Every model has easy to read computer etched timing marks.

All Dayco POWERBOND Race series balancers meet SFI specification 18.1.

Dayco Powerbond Underdrive
Under-driving the accessory pulleys to reduce parasitic power losses from the alternator, air conditioning, water pump and power steering at high engine RPMs. A smaller, lighter harmonic balancer is like a lightweight flywheel and can sharpen throttle response and allow the engine to rev out faster.
Underdrive pulleys have long been around and are a great way to release more power. The kits does this in a couple of ways, first the reduction of reciprocating mass the second to underdrive the accessories. Once installed you will notice a improvement in throttle response. This kit comes with the new harmonic balancer & a new water pump pulley. An FG 5.4 lt engine will require a new BA or BF belt at additional cost. 00038587
