Wilwood Front UTV4-C Anodized Four-Piston Brake Caliper, 0.25-Inch Rotor Width

This Wilwood UTV4-C is a front four-piston hydraulic caliper for the corresponding UTV brake arrangement. The anodized forged body uses four 1.25-inch stainless pistons, an M10 x 1.25 inlet and the nominal 0.25-inch rotor-width configuration. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems for motorsport, street-performance and specialized use, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Match the exact UTV brake package, 8.75-inch radial pattern and rotor offset before ordering. The maximum rotor diameter is 11.25 inches, but model identity and mounting measurements must be confirmed for the actual vehicle rather than inferred from the general UTV designation.
