Wilwood D154 Front Caliper Kit for GM Cars 1 or 2 Piston Forged Aluminum

Wilwood D154 Front Caliper Kit for GM Cars — 1 or 2 Piston Forged Aluminum Direct bolt-on replacement for late-1970s through early-2000s GM metric calipers. The Wilwood D154 front caliper kit delivers a lightweight, high-strength upgrade over OE cast-iron units for street and track use. Key Features Forged billet aluminum body — resists rust and bore pitting versus OE cast calipers. Choice of piston counts: 2.50" single piston (4.90 in² per caliper) or 1.62" two-piston option (4.12 in²) to maintain OE front-to-rear bias and master cylinder compatibility. Stainless steel pistons and competition-style high-temperature seals for reliable long-term performance. Direct fitment — mounts in stock location, uses original-style OE D154 pads and OE M10-1.5 banjo bolt brake line mounting. Includes Wilwood hardened slide pins and BP-10 high-friction brake pads. Weight savings and reduced maintenance compared to OE units; fits most wheels that clear factory calipers. Benefits Ideal for enthusiasts restoring or upgrading mid-size GM cars and small trucks, the D154 kit reduces corrosion issues and seal failures common to original metric calipers. It provides consistent, high-temperature braking performance for daily driving or occasional track use. Compatibility & Options Fits many GM models from 1978–2002 that used metric front calipers. Available in 1- or 2-piston configurations to match braking feel and bias requirements. Matching rear calipers and custom stainless steel brake lines available separately for complete system upgrades.
