Diesel parts guide

Shopping Duramax

Hilltop Diesel Performance organizes parts around real truck fitment so you can move from platform to the component you need without digging through an unrelated catalog. For Duramax applications, start with your exact year and engine, then verify configuration-specific notes on the product page before ordering.

Common upgrade and service paths include fuel delivery, injectors, turbochargers, intake and charge-air parts, exhaust, cooling, transmission components, filtration, sensors, gaskets, hardware and supporting installation parts.
