What vehicles did the D154 caliper originally come on?

The D154 caliper was used as original equipment on a wide range of mid-size GM cars and small trucks starting in 1978, and was still found on some GM models as late as 2002.

Product Details

If you're looking to upgrade the braking system on your classic GM car or truck, or even tackle a drum-to-disc conversion on a hot rod, the Wilwood D154 forged billet caliper is a solid choice. This caliper is designed as a direct bolt-on replacement for the original cast iron calipers found on many mid-size GM vehicles and small trucks from 1978 through 2002. It offers a significant upgrade in terms of weight and strength compared to the factory parts.

Wilwood builds these calipers from forged billet aluminum, making them both lightweight and incredibly strong. This construction is crucial for handling the increased heat and stress that comes with more demanding braking situations, whether you're on the street or in a competition setting. The 2.50-inch piston works with a 1.04-inch disc thickness, providing a good balance for improved stopping power. Its popularity in restricted class racing and custom builds speaks to its effectiveness and the wide availability of compatible brake pad compounds.
