This Wilwood cast iron GM Metric D154 caliper with a larger piston option is a bolt-on replacement for 1978 and later GM Metric systems often found in spec racing and economical disc conversions. Offered as a new cast unit instead of a rebuild, it requires the Wilwood hardened slide pin kit (part no. 230-0619) sold separately and provides a durable replacement for metric GM brake configurations.
