Harmonic Balancers
All Romac harmonic balancers are SFI 18.1 spec approved. These are offered in four styles. All 360 degreed and fully encapsulated outer rings via a shoulder at the rear and a serviceable circlip mounted at the front of the outer ring. All Romac balancers are individually consecutively marked, fully serviceable and need no special bonding with the elastomer. Balancers can be ordered with undersize bores to suit Scat and Eagle crank snouts; simply indicate this by adding the undersize to the P/N when ordering. To be sure of the bore size you need you should measure this prior to purchasing. A list is provided in our catalogue for standard factory bore diameters.
