03-04 Cobra Harmonic Balancer w/Metco Adapter #811/963
$715.00 – $730.00
SFI 18.1 Harmonic Balancer for Ford 2003-2004 Cobra with Metco and Lightning Force Adapter.
Using the combination of our #811 6 Rib Balancer along with our #963 “Metco” adapter, 03-04 Cobra owners now have an SFI approved option to the stock Balancer. Our adapter is designed to adapt the Metco Motorsports, Lightning Force Performance or Moto Blue interchangeable crank pulleys to our SFI approved Balancer.
NOTE: The use of this aftermarket balancer requires the removal of the stock crank support cage. Please see Part #813 for an OEM style Balancer for use with the stock crank support.
- Diameter: Metco Drive Rings
- Weight: 9.2 lbs
- Exceeds SFI 18.1 standards and is marked on front with SFI Sticker, and on the rear with SFI number stamped into unit.
- Works with Metco Motorsports & Lightning Force Performance Interchangeable Pulleys
- NOTE: The Super Duty Blower Hub option is a thicker hub that provides greater resistance to hub cracking under high power supercharged applications (750 rwhp and greater). This option includes a new custom made timing cover seal to adapt the oversized hub to a stock timing cover.
