OEM SPECS & DIMENSIONS
Professional Products Powerforce line of harmonic balancers are designed for maximum duty street use. Made of tough 65-45-12 nodular iron they are practically indestructible. The amount of elastomer contact with the hub and inertia ring has been increased to keep the ring from coming off. They are made to factory dimensions so they are a direct interchangeable fit. TDC and timing marks are permanently engraved.
Professional Products Powerforce+Plus line of harmonic balancers meet SFI Specifications which allows them to be used in organized racing events. Made of maximum strength 1045 steel, these are the ultimate in a racing balancer. These balancers are designed so that if an unlikely failure allows the inertia ring to come loose, it is captured onto the hub and cannot fly off. This is the ultimate racing damper but can also be used on street applications.
Professional Products' Restoration Balancers provides enthusiasts who are restoring older model vehicles with a very cost-effective balancer that is visually and mechanically identical to the Original Equipment balancer. The dimensions and timing marks are the same. They are factory color matched to the original equipment balancer.
