Crankshaft Dampers suitable for Alperform KBD LD series race cranks for race applications, fits crank using special fitting tools, uses special lip seal with same OD as original seal,

As used on our race winning engines since 2004, seal is as used with new design STD crank pulley

Please note that for a cank damper to work properly it should be an interference fit, not loose slide like AMLs TV damper, this means that it needs a special press & pull tool to fit & remove the damper.

However AMLs crank damper can be helped by use of our DB4 to AM V8 damper washer.
