$495.00$595.00

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 SFI 18.1 Approved Balancer is designed for BDS (Blower Drive Services) and other Roots Blower Pulleys to bolt right up. The damper provides a 6-bolt, “BDS” 2.76″ bolt pattern as well as a male 2″ pulley register. The damper features an all aluminum case design for light weight, stress-proof steel hub and 1040 steel inertia rings for durability. A wet clutch friction provides harmonic dampening for your street and race supercharged engines.
