2004.5–2007 5.9L Cummins Engines & Engine Parts
Shop engines and engine parts for 2004.5–2007 5.9L Cummins applications. This collection includes stock and upgraded long blocks, short blocks, cylinder heads, Builder Boxes, overhaul parts, pistons, rods, camshafts, bearings, gaskets and girdle systems.
Whether you are repairing a stock engine or planning a stronger build, choose components around the exact engine configuration and intended use. Use the exact model year and current injector, pump or turbo number because the 2004 mid-year break is important.
2004.5–2007 5.9L Cummins Engine Parts & Build Options
The 2004.5–2007 group covers the later high-output 5.9L common-rail platform. Industrial Injection catalogs this range separately from 2003–2004 because injector, turbo and other application details change at the mid-2004 break.
Industrial Injection's catalog for this year break includes stock and upgraded long blocks, short blocks, cylinder heads, Builder Boxes, overhaul parts, pistons, rods, camshafts, bearings, gaskets and girdle systems. That gives you options ranging from individual repair parts to larger engine-build components. Do not assume every 5.9L or 6.7L internal part crosses between generations.
Use the exact model year and current injector, pump or turbo number because the 2004 mid-year break is important. For short blocks, long blocks, Builder Boxes and cylinder heads, also review the exact included components before ordering.

Frequently Asked Questions
What engine platform is used in 2004.5–2007 Cummins applications?
This collection is built around the late common-rail 24-valve 5.9L. It uses high-pressure common-rail injection with a CP3 pump.
What is the difference between a Cummins short block and long block?
A short block centers on the assembled lower engine, while a long block adds the cylinder head and additional upper-engine components. Exact included parts vary by product, so use the individual listing as the final authority.
How do I verify Cummins engine-part fitment before ordering?
Use the exact model year and current injector, pump or turbo number because the 2004 mid-year break is important. For major assemblies or internal engine parts, compare the product specifications with the engine and component being replaced rather than relying on displacement alone.
