Wilwood Dynapro Low-Profile Rear Disc Brake Kit 140-11400-D for 12-Bolt Special Axle

Upgrade rear braking performance with the Wilwood Dynapro Low-Profile Rear Disc Brake Kit, part number 140-11400-D. Designed for vehicles using a 12-bolt special axle with an offset axle configuration, this complete kit combines a compact four-piston aluminum caliper with a drilled and slotted iron rotor for responsive stopping power and improved heat management. The black powder-coated finish provides a durable appearance suitable for performance, street, and custom applications.
The Dynapro low-profile design helps provide increased wheel and component clearance while maintaining the rigidity and clamping force expected from a multi-piston brake system. The four-piston caliper delivers balanced pad engagement across the rotor surface, helping promote consistent braking response during repeated use. The drilled and slotted rotor supports friction-surface cleaning and heat dissipation, making this Wilwood brake kit a practical upgrade over many original rear drum brake arrangements.
This Wilwood 140-11400-D kit is configured for rear installation and includes parking brake functionality for added convenience and vehicle usability. Its aluminum caliper construction helps reduce unsprung weight compared with heavier cast designs, while the black powder coat offers added surface protection and a clean, understated finish. Confirm axle configuration, rotor placement, wheel clearance, and application compatibility before ordering to ensure proper installation. The kit is intended for qualified installation using the manufacturer’s recommended procedures and compatible brake components.
