[More Info]

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.

Additional Notes
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. Standard DP6 calipers feature a high gloss black finish. Bright polished, high gloss red, and other custom Wilwood colors can be ordered to add personalized style for custom applications.
