Wilwood 140-13329-DR Forged Narrow Superlite 4R Big Brake Front Kit 14" Drilled Red w/Lines

The Wilwood 140-13329-DR is a Forged Narrow Superlite 4R Big Brake Front Brake Kit purpose-built for early Ford Broncos equipped with Dana 30 or Dana 44 drum spindles. At the heart of this kit is Wilwood's high-performance Forged Narrow Superlite 4R four-piston caliper, delivering exceptional stopping power in a compact, lightweight package. The kit ships complete with a 14.00" drilled rotor, red-finished calipers, and brake lines (Wilwood Line Kit 220-13319), providing everything needed for a straightforward big brake upgrade.

Key Features:

• Forged Narrow Superlite 4R four-piston caliper for superior braking capacity over OEM drum brakes
• 14.00" drilled rotor for improved heat dissipation and consistent fade resistance
• Application-specific engineering for Dana 30/44 drum spindle applications — utilizes the existing hub assembly for simplified installation
• Red powder-coated caliper finish for an aggressive, high-performance appearance
• Brake lines included (Wilwood Line Kit 220-13319) for a complete, ready-to-install package
• Radial caliper mount for rigid, precise caliper positioning

Wilwood's big brake kits are designed to complement suspension lifts, larger wheels, and tire upgrades common on off-road and restomod builds. The FNSL4R caliper's forged aluminum construction keeps unsprung weight low while maximizing structural rigidity under hard braking loads. This kit delivers a significant and measurable upgrade in braking performance, offering the stopping confidence demanded by serious street and trail driving.
