DCW Premium (DCWP) complete cylinder head for the Caterpillar C15, base number 2239250 (CAT reference 223-9250). Fully assembled in-house by our experienced cylinder head team — over 80 years of combined experience — using American-supplied valvetrain components, then multi-point QC inspected before it ships. Unlike a standard aftermarket complete head, every DCWP head is built and validated in-house and backed by a 2-year no-questions-asked warranty plus progressive engine damage coverage. New, loaded, and ready to install — transfer your own injectors.
