Wilwood Front Left Anodized Aero6-DM Caliper for Toyota Tacoma (2005–2023), Six-Piston Body

The anodized left front Wilwood Aero6-DM is a component of the documented six-lug Tacoma brake conversion. A forged body carries six differential stainless pistons, while the nominal 1.25-inch rotor channel and 5.04-inch mounting centers establish the caliper's interface. 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

Verify Toyota Tacoma 2005–2023 eligibility and the complete Wilwood package before selecting this left-hand unit. The kit uses 13.31-inch-diameter rotors at 1.26-inch width; follow its wheel-clearance and dust-shield instructions rather than assuming stock-rotor fit.

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.
