BDS/Roots Blower Pulley Style 7″ Damper for LSX Racing Applications #846


Just because you’re running a BDS Style Blower doesn’t mean you have to run a solid hub, you can STILL run a Damper and SAVE YOUR CRANK!

This 7″ Diameter SFI 18.1 rated Racing Balancer is designed for BDS (Blower Drive Services) and other Roots Blower Pulleys to bolt right up using the 2.760″ bolt pattern and 2″ male pulley register. It’s fully engraved for setting timing and is also available with integrated flying magnet crank trigger system.

The damper comes standard with Corvette length hub.
