Wilwood 140-15951 Aerolite 6R AERO6 Front Big Brake Kit 14-Inch 5-Lug Black

The Wilwood 140-15951 Aerolite 6R AERO6 Front Big Brake Kit delivers serious stopping performance for heavy-duty and extreme-duty applications. Engineered around Wilwood's high-capacity AERO6 six-piston calipers and 14.00-inch directional vane rotors, this kit is purpose-built for trucks that demand more than stock brakes can provide — whether towing, off-roading, or running upgraded wheel and tire packages.

This kit is designed for use with Wilwood's 1-Piece Iron Drop Pro Spindles and includes hubs compatible with both 5 x 4.75-inch and 5 x 5.00-inch bolt circle patterns, providing flexibility for a range of wheel configurations.

Key Features:

• AERO6 6-Piston Calipers — High-rigidity, radial-mount design delivers maximum clamping force and consistent pedal feel under sustained hard braking
• 14.00-Inch Directional Staggered Vane Rotors — Optimized vane geometry maximizes airflow and heat dissipation for long-duration, high-temperature durability
• Dual Bolt Circle Hub Compatibility — Includes hubs with 5 x 4.75-inch and 5 x 5.00-inch bolt patterns for broad wheel fitment options
• OE Master Cylinder Compatible — Fully compatible with factory master cylinder output and OE ABS function; no brake booster or master cylinder upgrade required
• Black Caliper Finish — Durable black powder-coat finish for a clean, aggressive appearance behind the wheel
• Requires Wilwood 1-Piece Iron Drop Pro Spindles — Will not fit original equipment spindles; Wilwood C10 Iron Pro Drop Spindles must be installed separately

The Aerolite 6R caliper features a lightweight body design that reduces unsprung weight without sacrificing structural rigidity — a direct benefit of Wilwood's motorsport engineering heritage. The kit is engineered for straightforward installation using common hand tools, and some applications may require Wilwood Flexline brake lines, sold separately.
