Wilwood 120-17954-RD AeroDM Forged Disc Brake Caliper - 4-Piston Red

The Wilwood AeroDM forged four-piston disc brake caliper delivers serious stopping power engineered for both street driving and demanding off-road use. Built on proven race technology, the AeroDM caliper features a versatile body design that adapts to a wide range of truck applications, making it a go-to upgrade for heavy-duty braking needs.

Variable lug geometry enables direct spindle mounting compatibility with Wilwood's proprietary 13.38" diameter rotors on many late-model trucks. Multiple piston volume options give the AeroDM the flexibility to meet a broad spectrum of heavy-weight braking requirements. Internal fluid ports eliminate the need for external fluid crossover tubes, and the absence of a massive center bridge assembly contributes to exceptional structural rigidity.

Stress-Flow Forged Aluminum Construction:

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

Key Features:

• Forged aluminum construction — stress-flow forging for maximum strength-to-weight ratio
• 4-piston design — delivers consistent, even clamping force across the rotor
• Variable lug geometry — supports direct spindle mounting with 13.38" proprietary rotors
• Internal fluid ports — cleaner routing, increased rigidity, no external crossover tubes
• Red powdercoat finish — corrosion-resistant and visually striking behind the wheel
• Street and off-road rated — engineered for heavy-duty braking demands in multiple environments
• Multiple piston volume options — versatile fitment across a wide range of truck applications

The Wilwood 120-17954-RD is finished in a bold red powdercoat and sold individually. It is part of Wilwood's AeroDM caliper line, available in multiple mounting configurations and finish options to suit your specific build requirements.
