Wilwood 140-2112-B Dynalite Rear Brake Kit for GM 12-Bolt

Upgrade the rear braking performance of your GM 12-bolt axle with the Wilwood 140-2112-B Dynalite Rear Brake Kit. Designed as a complete performance-oriented braking solution, this kit combines lightweight aluminum four-piston calipers with a plain iron rotor and offset mounting hat for dependable stopping power, responsive pedal feel, and consistent performance in demanding driving conditions. The kit is engineered specifically for compatible Chevrolet and GM 12-bolt applications.
The Dynalite calipers feature a durable aluminum construction with a black powder-coated finish that provides a clean appearance and helps protect the calipers from normal environmental exposure. Their four-piston design promotes balanced clamping force across the rotor, helping improve braking control and pad wear characteristics. The included plain iron rotor is well suited for street performance, restoration, and custom vehicle applications where reliable braking and practical serviceability are important.
This Wilwood brake kit includes the rear calipers, plain iron rotors, offset hats, and related components required for the specified application. Verify axle configuration, wheel clearance, rotor placement, and installation requirements before ordering to ensure compatibility with your vehicle and existing brake system. Professional installation and proper brake system bleeding are recommended for safe operation. The Wilwood 140-2112-B is not air restricted and does not require truck freight shipping.
