Wilwood 120-17458-BK AeroDM Six-Piston Forged Aluminum Disc Brake Caliper - Black

The Wilwood 120-17458-BK AeroDM is a forged six-piston disc brake caliper engineered to deliver heavy-duty stopping power for both street and off-road applications. Built on race-proven technology, the AeroDM caliper combines high-performance design with broad adaptability, making it a versatile solution for demanding heavy-weight braking requirements.

Variable Lug Geometry & Direct Mounting: The AeroDM features variable lug geometry that enables direct spindle mounting compatibility with proprietary 13.38" diameter rotors on many late-model trucks. Multiple piston volume options allow this caliper to be precisely matched to a wide range of braking applications and vehicle weights.

Stress-Flow Forged Aluminum Construction: The caliper body is stress-flow forged from a premium-grade aluminum alloy billet. The stress-flow forging process realigns the metal's internal grain structure to follow the contour of the caliper body, eliminating the stress points and grain interruptions that result from machining a standard straight billet. The result is a caliper with:

• Six-piston design for balanced, high-clamp braking force
• Stress-flow forged aluminum alloy body for maximum strength-to-weight ratio
• Superior clamping efficiency under heavy load
• Enhanced fatigue resistance against stress and distortion
• Variable lug geometry for direct spindle mounting on late-model trucks
• Compatible with 13.38" proprietary rotors
• Multiple piston volume configurations to suit varied braking demands
• Black finish for a clean, aggressive appearance
• Designed for street and off-road use

The Wilwood AeroDM caliper is part of Wilwood's Aero series, representing the pinnacle of bolt-on racing caliper technology adapted for high-performance street and off-road trucks. It is the ideal upgrade for drivers who demand race-grade braking performance without sacrificing fitment flexibility.
