Wilwood 140-14837-DR Forged Narrow Superlite Big Brake Front Hub Kit Drilled - FNSL6R 6R 12.88 Red

The Wilwood 140-14837-DR is a Forged Narrow Superlite 6R (FNSL6R) Big Brake Front Hub Kit featuring a 12.88" drilled rotor and a red powder-coated caliper finish. Engineered for OEM-style front spindles on classic American trucks — including the 1957–1967 Ford F-100 — this kit delivers a dramatic upgrade in braking power, thermal capacity, and visual impact over factory drum or disc setups.

The heart of this kit is Wilwood's FNSL6R six-piston billet forged caliper, stress-flow forged from premium-grade aluminum for superior strength and reduced unsprung weight. The narrow body design ensures broad compatibility with 17" and larger aftermarket wheels, making it an ideal companion to suspension lifts, wheel upgrades, and performance tire packages on custom show trucks and high-performance street or track builds.
