    Six Piston Stopping Power !

    The DP6 marks a noteworthy step in the evolution of the DynaPro caliper series. DP6 calipers offer the performance advantages of a larger pad and a six piston differential bore configuration, with complete bolt-on interchange ability to the four piston 5.25'' lug mount DynaPro models, and the long standing Dynalite caliper series.

    As with the previous DynaPro models, the strength of the DP6 is a combination of process and design. Premium grade alloy billets are stress-flow forged resulting in a highly efficient, high strength body. Stress flow forging re-aligns the internal grain structure of the metal within the contour of the caliper body. This process is proven to provide superior strength over any other process derived from castings or straight billet block machining. FEA assisted solid modeling design technology was employed to find the optimum balance between lightweight with superior strength against deflection and body separation under high load.

    In addition to the sturdy, yet stylish body, the DP6 incorporates race proven technology and the latest Wilwood performance enhancements. Pad clamping force is generated by six heavy wall stainless pistons configured in a leading to trailing edge differential bore pattern. The heavy wall pistons have been re-engineered to fully resist backside deflection at high pressures while maintaining balanced pad loading for even wear over the length of the pad. Stainless steel resists corrosion while inhibiting direct heat transfer from the pads to caliper body, seals, and fluid. Two choices for overall piston volume provide options to match caliper size with master cylinder output and bias requirements.

    The DP6 uses the upgraded type 6712 pad that provide the larger overall volume size from the previous Dynalite and DynaPro four-piston models. The pads are retaining with exclusive Wilwood Quick-E clips for simplified pad service and maintenance without caliper removal. Stainless steel SRS bridge plates are used to dampen engagement harmonics, eliminate pad rattle, and protect the caliper bridges from gouging by the pad edges. Four corner bleeds and internal fluid passages accommodate front or rear mounting and simplified gas evacuation regardless of mounting position.

  • Complete bolt-on interchange ability to the four piston 5.25'' lug mount DynaPro and Dynalite caliper series
  • Performance advantages of a larger pad and six piston differential bore configuration
  • Exclusive Quick-E clips for simplified pad service without caliper removal
  • Weights starting at just 7.70 pounds

    WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.


    WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
