Wilwood 140-14839-R AERO6 Front Big Brake Hub Kit 14.00" Red Calipers

The Wilwood 140-14839-R AERO6 Front Big Brake Hub Kit delivers maximum stopping performance with large-diameter rotors and a six-piston caliper design built for heavy-duty and extreme-duty applications. Featuring a bold red powder-coated finish, this kit is engineered to work with factory drum spindles, making it a straightforward upgrade for classic truck builds.

At the heart of this kit is the AERO6 six-piston caliper, Wilwood's flagship big-brake caliper designed to generate massive clamping force. The caliper features six stainless steel pistons, 4.04 square inches of total piston area, a radial mounting style, and 11.1 square inches of brake pad contact area using BP-20 compound pads.

The kit includes SRP drilled and slotted 14.00" diameter iron rotors that are 1-1/4" thick, with a directional staggered vane design for maximum heat dissipation and sustained high-temperature durability. Rotors are dynamically balanced and feature a lightweight aluminum hat with a black e-coat finish and a 1-3/4" hat offset. The dual-drilled lug pattern supports both 5x4.75 and 5x4.50 bolt configurations.
