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!

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.
