IMPORTANT NOTES AND RECOMMENDATIONS

1. SCAT AND EAGLE CRANKS / UNDERSIZE BORES
Eagle cranks for some reason are always produced with an undersize as standard and this undersize can often vary The snout size on these brands will always need to be measured/checked before purchasing.
All ROMAC Balancers can be ordered with undersize bores (0.001" to 0.0010") Please call us for more details on pricing and availability. To be sure of the bore size you need you should measure this prior to contacting us.

2. DRY SUMPS AND/OR OTHER BALANCER LOADING
If using dry sump pumps or items driven of the inner hub of the balancer please use a balancer with a Steel Inner Hub.

3. HIGH COMPRESSION AND LARGER STROKED ENGINES
We strongly recommend  the use of  a steel inner / alloy outer balancers for higher compressions and larger stroked engines.

4. BOLTING ACCESSORIES TO BALANCERS
Please only ever use factory length/short balancer to crankshaft bolts to retain Romac balancers - all accessories are to be bolted to the inner hub separately.
