Caliper Powerlite 1.38in Piston .860 Rotor

The WILWOOD Caliper Powerlite 1.38-inch Piston .860 Rotor is a high-performance four-piston aluminum brake caliper engineered for precision stopping power and superior thermal management in demanding automotive applications. Built with gray anodized aluminum construction, this brake caliper delivers fade-resistant performance across extended braking cycles, making it ideal for track use, street performance driving, and motorsport competition where consistent stopping force is non-negotiable.

The four-piston design distributes clamping force evenly across the brake pad surface, reducing uneven wear and improving brake response consistency. The 1.38-inch piston diameter combined with the .860-inch rotor thickness specification provides the mechanical advantage needed for vehicles requiring aggressive deceleration without excessive pedal pressure. The lightweight aluminum construction minimizes unsprung weight while maintaining structural rigidity, a critical factor for performance applications where brake feel and modulation directly impact driving precision.

This WILWOOD brake caliper suits performance enthusiasts upgrading factory braking systems on sports cars, hot rods, off-road vehicles, and autocross competitors. The Powerlite series is commonly installed as part of complete brake system upgrades where OEM calipers lack the thermal capacity or clamping force for high-heat environments. Verify fitment compatibility with your specific vehicle's rotor diameter and mounting configuration before purchase, as WILWOOD caliper sizing varies across their product line.

WILWOOD is recognized in the performance brake market for manufacturing precision calipers used in racing, restoration builds, and high-performance street applications. The gray anodized finish provides corrosion resistance and a professional appearance while maintaining the functional benefits of aluminum construction.
