Class 8’s are engineered individually on a per order basis by the factory applications engineering group working with the dealer sales person who works with the customer.

As mentioned by others a large number of factors are involved in a spec.


This applies more to heavy haul customers, like specialized C500s and T800s with enlarged radiators, hub reduction axles, that get used to haul transformers and power plant structures.

For a run of the mill OTR Class 8, I see 2 main classes: 80 - 90k GVW line haul, where hwy fuel efficiency rules; and flatbed / "heavy haul", with mid rise sleepers and steeper 46k rear ends. This probably covers 90% of your fleet / owner op purchases.

Here in BC tridems are popular, as we don't allow lift axles. They're in their own niche, not quite as heavy as real heavy haulers, but heavier than typical flat bed spec. They're usually T800s or Western stars with the largest radiator without going super wide hood.
