The Powerforce line of balancers are intended for non-SFI high performance applications. Although primarily meant for street use, these balancers are also suitable for racing applications where there is no requirement to meet SFI specifications.
It is not recommended to use these balancers in excess of 6,500RPM. Also, they are not recommended for marine or circle track applications due to excessive heat generated. While high temp elastomer is used in every balancer, certain applications are not suitable.
This damper is basically dimensionally the same as the 1970-'78 Nissan damper for L-Series engines without power steering. Will also work on later 1979-'83 engines without power steering or air conditioning, as it only has one accessory drive pulley. The front of the pulley has two tapped holes that would allow special fabricated pulleys to be adapted to the front of the damper if needed for additional accessory drives. The Professional Products Harmonic Dampers for L-Series Nissan engines are basically very similar to the popular "Euro" damper from Nissan Competition Division. The "Euro" damper is now discontinued and no longer available. We believe our two dampers are the only performance models available for these engines.
