Wilwood 140-5255-BD Drag Rear Brake Kit for Mopar/Dana with Forged Dynalite Calipers

Upgrade the rear braking performance of your Mopar or Dana-equipped drag vehicle with the Wilwood 140-5255-BD Drag Rear Brake Kit. This application-specific kit combines forged Dynalite four-piston calipers with drilled steel rotors and offset aluminum hats to provide reliable stopping performance, efficient heat management, and a purpose-built fit for demanding motorsports use. The gray anodized finish adds corrosion resistance and a clean, professional appearance.
The forged Dynalite calipers are designed for strength, reduced weight, and consistent pad alignment during repeated braking cycles. The 11.440-inch drilled steel rotors promote heat dissipation and help maintain predictable braking performance under track conditions. Aluminum offset hats support proper rotor positioning while helping reduce unsprung weight compared with heavier conventional components.

The integrated kit format simplifies component selection and helps ensure the major brake system parts work together as intended. Verify vehicle compatibility, axle configuration, wheel clearance, and hydraulic requirements before installation.
Wilwood has built a strong reputation for motorsports braking systems, and this Drag Rear kit delivers the engineered components needed for confident, repeatable braking. It is supplied as a complete rear brake package with gray anodized aluminum components and drilled steel rotors.
