Product details
A black forged housing carries the six differential stainless pistons in this left front Wilwood TX6-DM. The caliper's 12.68-inch direct-lug spacing belongs to the 2023-and-later Ford F-250/F-350 4WD conversion with nominal 1.50-inch-wide rotors. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc braking systems for motorsport, street-performance and specialized applications, with a component range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Compare the matching Wilwood rotor and front hose package with the truck's actual equipment. The later 4WD spindle geometry and complete wheel-clearance envelope need confirmation; this caliper is not an earlier F-250/F-350 interchange by appearance.
With 20+ years of experience, PMB Performance can help assess the brake hardware. Provide the caliper number, rotor dimensions and bracket measurements when asking about compatibility.
