(Part #8351206814)
                        

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.
