Wilwood 120-17591 AeroDM Forged Six-Piston Disc Brake Caliper

The Wilwood 120-17591 AeroDM Forged Six-Piston Disc Brake Caliper delivers serious stopping performance for street driving and off-road use alike. Built on a foundation of proven motorsport engineering, the AeroDM incorporates race-derived technology into a highly adaptable lug-mount body design suited for heavy-duty braking demands.

The caliper body is stress-flow forged from a premium-grade aluminum alloy. This specialized forging process realigns the metal's internal grain structure to flow with the contour of the caliper body — eliminating the internal stress points and grain interruptions that result from machining a straight billet block. The result is a caliper with superior clamping efficiency and exceptional resistance to fatigue, distortion, and stress under load.

Key Features:

• Six-piston forged aluminum construction for maximum clamping force and durability
• Stress-flow forged body optimizes internal grain structure for superior strength and fatigue resistance
• Variable lug geometry enables direct spindle mounting on many late-model trucks
• Compatible with proprietary 13.38" diameter rotors for a purpose-built upgrade solution
• Internal fluid ports eliminate external fluid cross-over tubes, reducing complexity and improving rigidity
• Multiple piston volume options provide versatility for a wide range of heavy-weight braking requirements
• Available in multiple powdercoat and anodized finishes to suit different builds and preferences

The AeroDM's internal fluid port design removes the need for external cross-over tubes and the bulky center bridge assembly typically found on conventional calipers, resulting in a cleaner, more rigid unit. Whether outfitting a performance street truck or a serious off-road build, the Wilwood AeroDM six-piston caliper offers the clamping power, durability, and installation flexibility to meet the challenge.
