Heavy Duty Wide Bobbins

AP Racing offer two options of wide bobbins for heavy duty disc arrangements offering improved stability in high torque applications.

  • CP4135 a forged one piece bobbin & stud providing improved and unrestricted airflow. (Replaces CP4015 bobbins).
  • CP7016 a two piece alternative for thicker mounting bell flanges, using separate bolt. The drawings and tables below provide all information required to aid the user.

Note: Special tool available, CP4015-137 to assist bobbin orientation whilst assembling both CP4135 and CP7016 bobbins.
