Product details
This black AeroDM is the right-hand six-piston front caliper documented for Wilwood’s 2024–2025 Toyota Tacoma package. Its 7.08-inch lug spacing and 1.62/1.38/1.38-inch staggered bores identify the Tacoma configuration. It is supplied as a caliper component for that engineered assembly, whose rotor, hose and hardware choices must be retained. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.

Fitment & Compatibility
Use DS1709 and the exact Wilwood kit reference to confirm the application. The package has its own rotor and hub geometry, so the bare caliper should not be treated as a direct substitution for the factory brakes. Check side, spindle interface, pad orientation and wheel clearance, and inspect the specified flexline routing through steering movement.
With over 20 years of parts experience, PMB Performance can help compare this component with your existing brake assembly. Include its caliper reference and any conversion-kit information.
