Wilwood D154 2-Piston Rear Caliper Kit for Custom Applications Forged Aluminum

Wilwood D154 2-Piston Rear Caliper Kit — Forged Aluminum for Custom Applications High-performance, low-maintenance rear caliper upgrade — the Wilwood D154 rear caliper kit is engineered as a direct bolt-on replacement for many factory single‑piston “Metric” rear calipers. Designed to match front D154 calipers for balanced braking and correct front/rear bias. Forged billet aluminum body for exceptional strength, reduced weight, and improved heat dissipation. Stainless steel pistons and competition-style high-temperature seals to eliminate rust, bore pitting, and seal failures common to OE units. Optimized piston area (1.96 sq‑in) for proper rear braking bias—smaller than many OEM pistons for safer, predictable stopping. Direct bolt-on fit to stock mounting locations and rotors; uses OE-style D154 brake pads and M10-1.5 banjo bolt for brake lines. Includes hardened slide pins and BP-10 high-friction pads for immediate performance. Compatible with most wheels that clear standard OE calipers. Ideal for street and track, the D154 caliper kit delivers reliable high-temperature performance, significant weight savings, and long-term durability for custom and retrofit rear brake applications.
