DUAL FORCE DRAG SYSTEM
The specialized carbon DFD or Dual Force Drag system used on all Makaira reels was specifically engineered to be mounted in the right side of the spool in order to bring all the mechanical workings closer together to maximize alignment and durability. The farther mechanical parts are separated the more opportunity there is for tolerance error and flexing which causes parts alignment issues. The DFD principal was specifically designed around the “Pull Bar Drag System”. The major advantage to a “Pull Bar Drag System” is that the drag is being pulled rather than pushed. The most common type of lever drag in the industry is the “Push Bar Drag System”. The Push Bar System places heavy pressure on the left side plate and utilizes the frame for overall stability which is a fatal flaw in
this type of design. This pressure creates frame flex, reducing drag pressure and causing tolerance alignment issues. This problem is further exaggerated on open top designs from other companies. One of the major benefits to the pull bar design is that there is no pressure placed on the frame. Therefore, our open top frame designs will not suffer frame flex found in our competitors reels. This highly efficient drag system was designed and engineered by Tiburon Engineering USA to increase maximum drag pressure, reduce side load pressure on ball bearings and improve heat dissipation for long term smoothness over extended periods. This Okuma DFD is considered a wet drag system comprised of two carbon fiber drag washers that are sandwiched together and bonded with a fiber glass core. Pure carbon washers are coated with a thin layer of Cal Sheet’s Universal drag grease for virtually zero start up inertia. These washers are compressed by two precision ground 17-4 grade stainless steel drag plates that have been ground flat then polished for maximum smoothness. These stainless steel friction drag plates have a minimum 32 Rockwell hardness allowing for high-end drag settings and consistently smooth drag performance at all ranges. The drag system is secured to the right side of the spool by a 6061-T6 grade aluminum cover that features Type- II anodizing for maximum alignment, strength and corrosion resistance.
