    The Forged Billet Dynalite is widely used in Road Race, Late Model Dirt, and Open Wheel motorsports. The latest applied developments and innovations in caliper design and manufacturing processes have resulted in substantial improvements in strength and performance over all comparable models.

    Forged Dynalites are the strongest calipers in the class, with weights starting at 2.80 pounds. Without even considering the overall greater strength and reliability of the forging, the reduced deflection tendencies and the resulting decrease in fluid volume displacement translate to increased clamping efficiency with less pedal travel. The bottom line is a taller pedal and better stopping power.

    • Pistion Count: 4
    • Area (in²): 4.80
    • Piston Type: Stainless
    • Fits .75" - 0.81" wide by 10" - 13.06" diameter rotors

    The Dyna Pro Single (DPS) billet caliper is the newest generation of calipers available as an upgrade or replacement for applications previously using the Dynalite Single (DLS) series. DPS calipers combine superior strength with performance enhancements to make these the best "Dyna" series calipers ever.

    The DPS is loaded with exclusive Wilwood performance enhancements. The calipers feature Quick-E-Clip pad retainers that support a 6812 type brake pad from the top. In addition to past pad service without caliper removal, the feature provides substantially stronger retention over the single Quick-Clip pin and 7012 type pads used in the previous DLS models.

    • Quick-E-Clip pad retainers supports brake pad from top
    • Heavy wall stainless steel pistons
    • Stainless steel SRS bridge plates eliminate pad rattle and dampen vibration
    • Internal fluid passages
    • Four corner bleed screws allow mounting in any front, rear, left, or right side position

    Narrow Mount DynaPro (NDP) forged billet calipers represent the next generation of calipers available as an upgrade or direct replacement for the popular Narrow Mount Dynalite model series with 3.50" mounting. NDP calipers combine superior strength with several new performance enhancements to make these the best "Dyna" series calipers ever built.

    The strength of the new DynaPro is a combination of process and design. NDP calipers are stress-flow forged from premium grade billet. Stress-flow forging realigns the grain structure of the metal within the contour of the body design. This process produces a part with superior strength over parts simply machined from straight grained blocks of billet. The FEA generated body design incorporates a highly fortified radial transition that eliminates steps and shoulders between the piston housings and the bridges. Incorporating a radius in this critical area substantially increases resistance to deflection and caliper body separation under load. For additional strength, all NDP calipers are fitting with center bridge bolts to provide additional resistance against separation over the center of the pads. Structural deflection and volume displacement testing have proven the efficiency of this innovative design. Reductions in overall deflection, and the subsequent decreases in fluid volume displacement, translate to increased clamping efficiency with less pedal travel. The bottom line is a firm, responsive
