Product Description

The Wilwood 120-8729 Powerlite Radial Mount Brake Caliper is a high-performance, lightweight 4-piston caliper designed for universal use in custom brake setups, motorsports, and performance builds. Forged from high-strength aluminum with a precision stress-flow design, this caliper offers strong clamping force with reduced unsprung weight, making it ideal for street, track, and off-road applications where tailored bracketry can be used to mount it to your vehicle's hubs.

Equipped with Quick-clip pad retainers and SRS stainless steel bridge plates, the 120-8729 caliper allows easy pad changes and improved pad stability, reducing noise and wear. Its radial mount design provides flexibility for adapting to many rotor sizes (approx. 9.45"-11") and mounting configurations, but because this is a universal product, fitment must be confirmed by measuring your vehicle's brake rotor, hub, and bracket requirements prior to installation.

This caliper is sold individually and does not include brake pads, bracket kits, or fittings, allowing you to select components that best suit your application - from vintage muscle cars to custom race cars. Always use proper mounting hardware and safety checks when installing universal brake components.
