Wilwood 140-15981-D Dynapro Radial Front 12" Big Brake Kit Black, Drilled, 1970-1990 GM A/B/F/X Body

Wilwood 140-15981-D Forged Dynapro Radial Front 11.75" Big Brake Kit With Black Calipers & Drilled Rotors For 1970-1990 GM A/B/F/X Body With Wilwood Drop Spindle Front

This NDPR Big Brake Kit is designed for the vehicles running WWE AFX Pro spindles and wanting to stay with a 14” wheel. This AFX Pro Spindle brake kit fits 1964-1972 GM A Body, 1967-1969 GM F Body, 1968-1974 GM X Body vehicles. NDPR Brake Kits feature Aluminum Hub assemblies, Forged Narrow Dynapro 4-piston calipers and two piece 11.75” SRP drilled or HD plain face rotors with aluminum rotor adapters to deliver the ultimate combination for braking power. Accesspeed feels that the strength of the DynaPro is a combination of process and design. The process of stess-flow forging re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This produces a part with superior strength over machined block billet parts or castings. The FEA generated body design features a radial transition between the piston bores and caliper bridges. This eliminates macined steps and shoulders in this critical strength area and substantially increases the resistance against deflection and body separation under high load. Structural deflection and volume displacement testing have proven the efficiency of this innovative design. The bottom line is a firm pedal with outstanding stopping power. The Narrow DynaPro calipers feature heavy wall stainless pistons to provide addition protection against corrosion and heat transfer from the pads. All DyanPro calipers can also be optioned with Thermlock pistons for maximum thermal protection in sustained high-heat applications. The DynaPro incorporates other exclusive Wilwood performance enhancements. Stainless SRS bridge plates eliminate caliper bridge wear from pad gouging while dampening noise and vibration during engagement. Internal fluid passages eliminate the need for external crossover tubes and four corner bleed screws allow effective gas evacuation regardless of mounting location. Built exclusively for 14” and larger wheels, NDPR kits enhance tire and suspension upgrades on street and track machines.
