Wilwood Dynalite Rear Disc Brake Kit for GM 12-Bolt, 4-Piston Caliper, 12-Inch Drilled and Slotted Rotor

Upgrade the rear braking performance of your GM 12-bolt axle with the Wilwood Dynalite Disc Brake Kit, part number 140-2112-BD. This complete brake system is engineered for dependable stopping power, consistent pedal feel, and reduced unsprung weight compared with many conventional factory-style brake assemblies. It is designed for applications requiring a rear four-piston caliper and a 12-inch rotor package.
The kit includes a lightweight aluminum Dynalite four-piston caliper finished in a durable black powder coat, along with a drilled and slotted iron rotor for effective heat management and reliable braking performance. The rotor design helps promote friction material cleaning and supports stable braking during repeated use. An offset aluminum hat provides the appropriate rotor positioning for compatible GM 12-bolt axle installations while helping reduce rotating mass.
Wilwood part number 140-2112-BD is intended for performance-oriented street, track, and custom vehicle builds where improved braking control and component quality are important. The rear disc brake configuration offers a clean, modern alternative to drum brakes and is supplied as a coordinated kit for easier component matching during installation. Verify axle configuration, wheel clearance, and vehicle application requirements before ordering.
This Wilwood brake kit is not air restricted and does not require truck freight delivery. Professional installation is recommended, including proper hydraulic connection, rotor and caliper alignment, brake system bleeding, and final inspection. Always follow Wilwood installation instructions and confirm compatibility with the complete vehicle braking system.
