Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Disc Brake Kit, Rear, UTV6, 6 Piston, Black Calipers, 11.25 in. Rotor, Solid Rotors, BP-10 Pads, Polaris, Kit

Wilwood UTV6 brake kits are offered for the front and rear of your off-road machine. The kits pair dynamically mounted rotors and upgraded 6-piston calipers.

The rotors reduce thermal stress, prevent piston knockback from rough terrain, and their steel construction, along with a greater diameter and thickness offer less distortion. They have a black Electro Coat finish and are available drilled or solid. The forged aluminum, differential-bore, 6-piston calipers reduce deflection and provide more uniform engagement to increase braking force and improve feel. The calipers are available with a red or black powdercoat. Calipers in Wilwood Race kits have a Type III Ano finish.

Available for popular Side x Side machines, Wilwood UTV6 brake kits will improve your UTV's braking performance. Kits include brake pads. Choose the preferred kit(s) designed for your machine.
