Wilwood D154 Front Caliper Kit – Red with 1.62-inch Pistons for GM Vehicles

Description

The Wilwood D154 Front Caliper Kit offers a high-performance, lightweight upgrade designed for mid-size GM cars and small trucks originally equipped with OE cast iron “Metric” calipers starting from 1978 through 2002. This direct bolt-on kit features forged billet aluminum caliper bodies, stainless steel pistons, and competition-grade high-temperature seals, ensuring resistance to rust, bore pitting, and seal failures common in OE designs. These calipers deliver reliable, low-maintenance performance suitable for both street driving and track use, while significantly reducing unsprung weight for improved handling and braking response.
The D154 calipers mount in the original location over stock rotors, preserving factory fitment and compatibility. They utilize the original style OE D154 brake pads and feature an OE M10-1.5 banjo bolt mounting for brake lines. With a piston diameter of 1.62 inches, each caliper provides a piston area of 4.12 square inches, maintaining the factory front-to-rear brake bias and compatibility with stock master cylinders. The kit includes Wilwood’s hardened slide pins and high-friction BP-10 brake pads, ensuring consistent performance and durability. These calipers are compatible with most wheels that clear OE calipers, allowing for versatile installation options.
Designed for enthusiasts seeking a balance of performance and reliability, the Wilwood D154 calipers are an ideal upgrade for street and track applications. They can be paired with matching rear calipers for complete brake system upgrades and are compatible with custom stainless steel brake lines for customized setups. This kit provides a substantial weight savings over stock cast iron calipers, offering a significant advantage in vehicle handling and braking efficiency without sacrificing durability or safety.
