Mack – further truck models: collective page for the US brand outside the named series, from the B and R models through CH and Granite to TerraPro, five- to eight-cylinder engines, gross weights up to 28.5 tonnes
This page gathers trucks from the US brand Mack that the register could not assign to a named series – from 1950s-to-1970s classics such as the B-61 and LTL, through the R and CH series, to newer models like Granite, Pinnacle and TerraPro. Mack was founded in 1900 in Brooklyn, later moved production to Allentown, Pennsylvania, and has belonged to the Volvo Group since AB Volvo's 2001 acquisition; the bulldog hood ornament has been the brand's mark since the 1930s. The model codes usually denote series and axle configuration, with R and CH covering long-haul tractor units and Granite and TerraPro covering construction and waste-collection vehicles.

The register lists 81 versions here with five- to eight-cylinder engines, displacements up to 17.0 litres, kerb weights up to around 19.5 t at gross vehicle weights of 4,804 to 28,500 kg, lengths of 5,530 to 12,000 mm and widths of 2,240 to 2,900 mm.
Mack has been a fixture in North American long-haul transport, construction and waste management for over a century, competing there chiefly with Kenworth, Peterbilt, Freightliner and International; outside North America the brand is far less common, which affects parts sourcing and workshop availability.
On classic B, R and LTL models, check frame corrosion, the condition of leaf springs and drum brakes, and the originality of engine and gearbox; on the newer CH, Granite and TerraPro model years, check the turbocharger, exhaust after-treatment and wear on the automated manual gearboxes. Parts for current series run through the Mack dealer network, while historic models are sourced through specialist American classic-truck dealers.
