Does HHP carry parts for Mack diesel engines?
Yes. HHP carries over 300 parts for Mack diesel engines, with coverage for the E7, MP7, and MP8 engine families. Many Mack parts at HHP are cross-listed with compatible Volvo engine models due to the shared architecture between the two brands — the Mack MP8 and Volvo D13 share the same engine platform, as do the Mack MP7 and Volvo D11. Part categories available for Mack engines include engine rebuild kits, cylinder heads, turbochargers, fuel injectors, gaskets, EGR and aftertreatment components, camshaft and valve train parts, pistons and liners, and lubrication system components. Both new and remanufactured parts are available depending on the component type.

Does HHP carry parts for Case or New Holland diesel engines?
Yes. Highway and Heavy Parts carries diesel engine parts for Case and New Holland equipment through the Case/New Holland category.

Does HHP carry parts for Hino or Isuzu diesel engines?
Yes, though in a more targeted capacity. HHP carries a focused selection of parts for Hino and Isuzu diesel engines, which are commonly found in medium-duty trucks and delivery vehicles operating in the North American market. Hino engines are used in Hino-branded trucks as well as some Toyota commercial vehicles, while Isuzu engines power Isuzu NPR, NQR, and NRR trucks along with a range of other commercial applications.

What types of parts does HHP carry across all OEM brands?
Regardless of the OEM brand, Highway and Heavy Parts stocks parts across the same core component categories for every diesel engine manufacturer in their catalog. Available part types include engine rebuild kits for inframe and overhaul applications, cylinder heads and head components, fuel injectors and fuel system parts, turbochargers, gaskets and seals, pistons, liners, and rings, engine bearings, camshaft and valve train components, EGR and aftertreatment parts, lubrication system components including oil pumps, cooling system parts including water pumps and EGR coolers, air compressors, and electrical system components. Availability varies by brand and engine model, with larger catalogs for high-volume brands like Caterpillar, Cummins, and John Deere and more targeted selections for specialty brands.
What if I can’t find parts for my diesel engine brand or model at HHP?
If the specific part or engine brand you need is not listed in the HHP online catalog, that doesn’t necessarily mean HHP can’t help. Highway and Heavy Parts has access to a broad supplier network and stocks hundreds of thousands of parts beyond what is shown on the website.
