Big Block Ford BDS Pulley Style 7 Inch Blower Damper with Long Snout #216

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. It features all aluminum case design for light weight, stress-proof steel hub and 1040 steel inertia rings for durability. Wet clutch friction style precision machined harmonic dampening for street and race engines.

This model is made for Long Snout Crankshafts. When using a short snout crankshaft, please use the #217 damper.
