The Ford 6 cyl is a serpentine belt engine and benefits from 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.
Gains of upto 10rwkw have been found with the underdrive balancer.

The Powerbond 20% under drive balancer for the Ford DOHC 6 engine is SFI approved for all forms of motor sport. The precision CNC machined steel hub and intertia ring is assembled using Powerbond’s pressure bonded rubber eliminating balancer separation and spinning. Every Powerbond unit is dynamically balanced at the factory for smooth running at ultra high RPMs

This kit includes the underdrive harmonic balancer, belt and idler pulleys.
