6061 T6 Aluminum 3-bolt Crankshaft Mandrel with 1" industry standard shaft size attaches to front of balancer and locates with a lip on the balancer for perfect concentricity. Utilizes a 1/8" standard keyway slot which allows you to use this mandrel with pulleys from many different manufactures, including GZ Motorsports. A crank trigger wheel may be installed on the front of the mandrel or on the balancer with the mandrel installed over it. The mandrel may be drilled to 1/2" for use with a long crank bolt if desired, GZ Motorsports can do this upon request.

All mandrels are designed to be attached to the balancer using the pulley mounting holes located on the balancer. This allows the crank bolt and washer to remain in place as required by aftermarket balancer manufactures. All mandrels come with a 4" long spacer so that each mandrel pulley can be accurately located on the mandrel by cutting each to length and an end cap and bolt. The mandrels can be shortened as desired as the threaded 7/16 center hole is 2" deep. Each mandrel is of length to allow a mandrel pulley to be at a maximum distance of 4.5" from the back side mounting face, or face of balancer. All mandrels are compatible with crank trigger wheels either located on the balancer, or mandrel side.
