Wilwood 140-3018-BD Forged Dynalite Pro Series Rear Disc Brake Kit with Drilled Rotors

The Wilwood Forged Dynalite Pro Series (FDL) Rear Disc Brake Kit (Part No. 140-3018-BD) is a complete rear brake conversion engineered for popular muscle car rear axles — specifically the Ford 8.8-inch 5-lug — on applications where individual wheel parking brake assemblies are not required. This kit delivers optimized, balanced stopping power for off-road, competition, and custom street builds.

At the heart of the kit is Wilwood's renowned Forged Billet Dynalite 4-piston fixed caliper, paired with a 2-piece hat and rotor assembly. The two-piece rotor design offers meaningful weight savings while promoting rapid heat dissipation compared to solid one-piece units. The cross-drilled rotor surface improves outgassing, increases cooling airflow, and sweeps away water and brake dust — reducing fade during sustained or high-heat braking events.

Key Features:

• Forged billet Dynalite 4-piston calipers — fixed design applies even, direct clamping force to both sides of the rotor for consistent bite and reduced pad distortion
• Cross-drilled 2-piece rotor assembly — 309 x 20mm rotor with lightweight hat for improved thermal management and show-quality appearance
• High-friction brake pads included — optimized for balanced front-to-rear braking bias
• Multiple caliper finish options available — black anodized and polished finishes to complement custom wheel and suspension builds
• Fits Ford 8.8-inch rear axle — 5-lug, designed for applications without individual wheel parking brake
• Sold as a complete kit — includes calipers, rotor/hat assemblies, pads, mounting brackets, and required hardware
• Caliper inlet fitting: 1/8-27 NPT
• Made in USA by Wilwood Engineering

The FDL Pro Series rear kit is ideal for pro-street, drag racing, off-road, and custom show builds seeking a bolt-on rear disc brake upgrade with race-proven hardware. Note: hydraulic lines, fittings, and parking brake components are not included.
