International / Navistar Parts

JAK'S Diesel stocks parts for International / Navistar diesel engines, including the workhorse DT466 family, for trucks, buses, ag and vocational equipment. We carry PAI Industries aftermarket components alongside our own JAK'S Diesel Heads, so you can rebuild, repair, or upgrade without overpaying for the OEM tag.

Not sure which part fits your engine? Send us an OEM, competitor, or superseded number and we'll cross-reference it.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 and we'll confirm fitment fast.
