Wilwood 120-17591-RD AeroDM Forged Disc Brake Caliper - 6-Piston Red

The Wilwood AeroDM Forged Six-Piston Disc Brake Caliper (120-17591-RD) delivers serious stopping power for demanding street and off-road applications. Built on proven race technology, the AeroDM caliper combines a versatile body design with variable lug geometry, enabling direct spindle mounting with proprietary 13.38" diameter rotors on many late-model trucks. Multiple piston volume options give this caliper the flexibility to handle a wide range of heavy-duty braking requirements.

Key Features:

• Stress-Flow Forged Aluminum Body: The caliper body is forged from a premium-grade aluminum alloy billet using Wilwood's stress-flow forging process, which realigns the metal's internal grain structure to follow the contour of the caliper body — eliminating the stress points and grain interruptions caused by conventional billet machining
• Superior Strength and Fatigue Resistance: The stress-flow forging method produces a caliper with outstanding clamping efficiency and exceptional resistance to fatigue, distortion, and stress under load
• Six-Piston Design: Six pistons provide even, consistent clamping force across the brake pad surface for improved braking performance and pad wear
• Variable Lug Geometry: Enables direct spindle mounting on a wide variety of late-model truck platforms
• Multiple Piston Volume Options: Allows tuning of brake bias and pedal feel to suit different vehicle weights and braking styles
• Race-Derived Technology: Engineering and design principles drawn directly from Wilwood's motorsport program, adapted for street and off-road use
• Finish: Red anodized/painted caliper body

The Wilwood AeroDM caliper is an ideal upgrade for truck owners and off-road enthusiasts seeking race-grade braking performance with broad vehicle compatibility. Paired with Wilwood's proprietary 13.38" rotors, this caliper provides a complete, high-performance braking solution built to withstand the rigors of heavy loads and demanding driving conditions.
