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.
These dampers are the dimensional duplicate of the O.E. damper used on the 2V engine. If used on a 4V engine, the accessories (alternator, A/C, etc) will rotate 3% slower than stock. Normally this is not a significant amount. This is due to a slightly different diameter of the damper. These dampers do not have timing marks on them but do have a notch in the back rim of the damper indicating TDC. These two dampers represent the most affordable high quality dampers available for this increasingly popular engine. See other areas of this site for additional products we offer for the 4.6L 2V engine which includes a terrific intake manifold, an upper plenum, and several extremely affordable high performance throttle bodies.
