BALANCER CHEV 400 6-3/4in

Professional Products' 6-3/4 inch damper is for use on externally balanced small block Chevy engines. This would typically include 383 and 400 cubic engines. Note that although this damper has a bolt-in counterweight, the damper cannot be used without the weight. Due to the windows cut in the front face of the damper, if the counterweight is removed, the damper is still not a neutral balance damper. If you need a neutral balance 6-3/4 inch damper, use PRP80000.
