Wilwood 140-14838-R Forged Narrow Superlite Front Hub Brake Kit - FNSL6R 6R 14.00 Red

The Wilwood 140-14838-R Forged Narrow Superlite 6R (FNSL6R) Front Hub Brake Kit delivers a powerful big-brake upgrade with a 14.00" rotor and a red anodized six-piston caliper. Engineered specifically for traditional OEM spindles on American trucks, this kit is purpose-built to dramatically increase front braking capacity while adding underhood visual appeal.

At the heart of this kit is Wilwood's Forged Narrow Superlite 6R (FNSL6R) billet six-piston caliper — a radial-mount design that combines an extremely rigid body structure with superior heat dissipation. Paired with a 14.00" diameter slotted rotor, this combination offers the maximum braking bite and fade resistance demanded by high-performance street and track use.

Key Features:

• Forged Narrow Superlite 6R (FNSL6R) six-piston billet aluminum caliper in red anodized finish
• 14.00" diameter rotor for maximum braking surface and heat capacity
• Engineered for traditional OEM spindles on American trucks
• Designed exclusively for 17" and larger wheels
• Radial-mount caliper design for optimized pad and rotor contact
• Multiple rotor finish options available across the FNSL6R kit lineup (slotted, drilled, or plain)

• Compatible with custom show builds and high-performance dual-purpose street/track applications

The FNSL6R front hub kit is the ideal choice for builders looking to complement wheel, tire, and suspension upgrades with a braking system that matches their performance goals. The red caliper finish adds a bold, race-inspired look visible through open-spoke wheels.
