Wilwood 120-13516-BK Powerlite Radial Mount Brake Caliper - 4-Piston Black

The Wilwood 120-13516-BK Powerlite 4-Piston Radial Mount Brake Caliper delivers race-proven stopping power in a lightweight, stress-flow forged aluminum body finished in black anodize. Engineered for high-performance street, sports, rally, and off-road applications, this caliper pairs advanced forging technology with a sleek, compact profile that fits a wide variety of custom brake system builds.

Key Features:

• 4-Piston Radial Mount Design — Pure race-derived architecture adapted for a broad range of performance and motorsport applications
• Stress-Flow Forged Aluminum Body — Forging process re-aligns the metal grain structure to the contour of the caliper body, maximizing strength while minimizing weight
• FEA-Optimized Radial Transition Design — Engineered radius between piston housing and caliper bridges substantially increases resistance to deflection and caliper separation under load
• 1.00 in. Diameter Pistons — Four pistons deliver balanced, consistent clamping force across the rotor surface
• Compatible Rotor Thickness: 0.350–0.500 in. — Accommodates a range of rotor specifications
• 1.00 in. Mount Spacing — Radial mount configuration for precise, rigid caliper positioning
• Black Anodized Finish — Durable corrosion-resistant finish for long-lasting appearance and protection
• High-Temperature Durability — Engineered to perform reliably in demanding, high-heat braking environments
• Sold individually

The Wilwood Powerlite series is ideal for builders and racers who demand lightweight, stiff, and thermally capable brake components. The stress-flow forging process and FEA-generated design eliminate the structural compromises found in machined billet calipers, making the 120-13516-BK a trusted choice for sports cars, formula-style racers, rally builds, and performance off-road vehicles.
