Product details
This red left-hand AeroDM supplies the caliper portion of Wilwood’s front conversion for the documented 2024–2025 Toyota Tacoma application. Six stainless pistons work in a forged body with internal hydraulic crossovers. Its 5.06-square-inch piston area and 7.08-inch lug spacing distinguish the working configuration that must match the rest of the brake system. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.

Fitment & Compatibility
Compare the existing brake package with DS1709 and its specified rotor before purchasing. The full kit determines rotor position, spindle mounting and hydraulic-line requirements. Check left-hand orientation, fitting clearance and the wheel template; the caliper’s nominal rotor opening alone cannot establish compatibility with another Tacoma or an unrelated conversion.
