Wilwood 140-13731-D Forged Narrow Superlite 4R Rear Brake Kit

The Wilwood 140-13731-D Forged Narrow Superlite 4R rear disc brake kit delivers a comprehensive big brake upgrade specifically engineered for 1965-1977 Ford Bronco rear axles with Big Ford flange and bearing configuration and 2.00-inch axle offset. This complete kit transforms rear braking performance while maintaining parking brake functionality through an integrated drum-style parking brake assembly.

Key Features:

• Forged Narrow Superlite 4R four-piston calipers for superior clamping force and heat dissipation
• Two-piece vented rotors available in 13-inch or 14-inch diameter for optimized thermal management
• High-performance BP-10 compound brake pads included for excellent stopping power and fade resistance
• Internal drum-style parking brake system provides strong static holding power in a clean, hidden design
• Engineered to balance with front big brake upgrades on Bronco platforms
• Available in multiple caliper finish options and rotor designs for custom appearance
• Direct bolt-on application for Big Ford 2.00-inch offset rear ends

This kit provides a complete rear brake solution that combines modern disc brake performance with reliable parking brake function. The forged aluminum construction reduces unsprung weight while the four-piston caliper design ensures even pad wear and consistent brake response. The concealed parking brake mechanism eliminates unsightly external cables while delivering superior holding force compared to traditional caliper-integrated systems.
