Cummins 6C 8.3 Parts
Not sure which part you need? Use our parts-request checklist.
The Cummins 6C 8.3L is a workhorse mid-bore inline-six found in vocational trucks, fire apparatus, RVs, agricultural equipment, and marine and industrial gensets. JAK'S Diesel stocks aftermarket and own-brand parts for the 6C family — including 6CT, 6CTA, and the later ISC variants — from cylinder heads and fuel injectors to turbochargers, gaskets, and complete rebuild kits.
Working from an OEM, competitor, or superseded number? Cross-reference it with us and we'll confirm fitment before you buy. Most orders ship same-day from Colorado, with free freight on orders over $1,000. Call or text (720) 445-6249.
