Working directly with ATI to develop a damper specifically to suit the stroke of the Barra engine, we manufacture a custom hub to fit the Barra engine.
We pioneered this upgrade in 2014 and as part of our ongoing commitment to produce components of the highest quality; in 2021 we made a number of improvements “ details as follows:
 
Internally ground bore for precise fit to the snout of the crank.
External centreless grinding of the seal track to ensure no leaks from the harmonic balancer seal.
Revised chrome moly washer to suit the ATI damper. Includes 1.5mm shoulder for concentric positioning of the washer inside our custom hub.
Custom made billet 4340 crank bolt with 31.5mm diameter flange built in.
Supplied with Nord-Lock locking washer
 
ATI balancer kit also comes with high tensile bolts to mount the damper mass onto the crank hub.
