Caterpillar C16 & C18 Parts
Not sure which part you need? Use our parts-request checklist.
Parts for the Caterpillar C16 and C18 big-bore diesels — the high-horsepower end of CAT's heavy-duty lineup. The C16 is a close, higher-output relative of the C15/3406E big-bore family, while the C18 is CAT's larger-displacement big-bore. Shop cylinder heads, fuel injectors, turbochargers, gaskets, and complete inframe and overhaul rebuild kits, with PAI Industries aftermarket coverage and JAK'S Diesel performance heads.
Not sure a number fits your block? Send us the OEM, competitor, or superseded part number and we'll cross-reference it. Most orders ship same-day from Colorado, with free freight over $1,000. Call or text (720) 445-6249 or request a quote.
