Wilwood D154 Rear Caliper Kit - Black with 1.12-inch Pistons for 1.04-inch Rotors

Wilwood's D154 Rear Caliper Kit offers a matching rear replacement option for our front D154 calipers. It is a direct bolt-on 2-piston replacement for the factory original single piston "Metric" calipers used on many custom application rears. With the added benefit of smaller rear piston sizing (1.96 sq-inches of area) not normally available in OEM calipers, for correct front and rear bias. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put an end to the rust, bore pitting, and seal failures that plague the OE caliper design. D154 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. D52 calipers mount in the stock location over stock rotors; use the original style OE D154 brake pads and an OE M10-1.5 banjo bolt brake line mounting. Calipers can be used with most wheels that clear the OE calipers. Kits contain Wilwood’s hardened slide pins and BP-10 high friction pads.

The Wilwood D154 Rear Caliper Kit, part number 140-12101-BK, is designed to deliver high-performance braking for custom applications. Featuring forged billet aluminum bodies and stainless steel pistons, this kit offers enhanced durability and resistance to rust, bore pitting, and seal failures common in OEM calipers. With a compact 1.12-inch piston size, it ensures proper brake bias when paired with the front D154 calipers, providing balanced stopping power on both street and track vehicles. The calipers are a direct bolt-on replacement, mounting in the stock location over OE rotors using original style brake pads and banjo bolts, simplifying installation without modifications. The included BP-10 high friction pads and hardened slide pins guarantee low maintenance and reliable high-temperature performance, making these calipers suitable for demanding driving conditions. Compatible with most wheels that clear OE calipers, the Wilwood D154 rear calipers are an optimal upgrade for enthusiasts seeking improved braking response and reduced weight in their custom builds.
