Product Description

The Wilwood 140-12099-BK D154 front caliper kit is a performance-focused upgrade for classic GM "Metric" brake applications (1978-2002). Featuring forged billet alloy construction, dual 1.62" stainless pistons, and BP-10 high-friction pads, it delivers improved stopping power, weight savings, and fade resistance--all while maintaining the original front/rear brake bias and compatibility with factory master cylinders.

Designed for bolt-on installation using stock spindles, OE brake lines, and mounting hardware, this kit requires minimal modification and is ideal for restorations, muscle car builds, or light-track use. The black powder coat finish and OE-style fitment ensure reliability and aesthetics, while preserving vehicle authenticity and drive quality.
