Wilwood D154 2-Piston Front Caliper Kit Red for 1978-2002 GM (1.62in Piston / 1.04in Rotor)

Fits select 1978-2002 GM mid-size cars and small trucks originally equipped with factory "Metric" cast iron calipers.

The Wilwood D154 Front Caliper Kit (MPN: 140-12099-R) provides a high-performance, lightweight alternative to heavy OE cast iron calipers. These dual-piston units are engineered from forged billet aluminum, significantly reducing unsprung weight while offering superior strength and heat dissipation. Designed as a direct bolt-on replacement, they mount in the factory location over stock 1.04-inch thick rotors and utilize original style M10-1.5 banjo bolts.

Equipped with stainless steel pistons and competition-style high-temperature seals, the D154 kit eliminates common failure points like bore pitting and rust. The dual 1.62-inch piston configuration provides 4.12 square inches of total piston area, delivering consistent clamping force and high-temperature reliability for both street and track applications. This kit includes Wilwood’s hardened slide pins and BP-10 high-friction pads to complete the installation.
