Description

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.
