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.
At 5.08 lbs. this is one of the lightest all steel dampers made for a SB Chevy. It is 6" in diameter and 3/4" thick. Keep in mind that to do the best damping job, a heavy inertia ring is required. So this damper provides enough damping to avoid crank breakage for those racers primarily looking for the lightest rotating weight they can get. Includes 60° of timing marks. This is not an SFI-spec damper.
