About Diecast Masters
Diecast Masters is the leading manufacturer of die-cast Caterpillar scale models, producing replicas under official Caterpillar license. Their High Line Series offers the most detail, while the Core Classics Series provides great value at a lower price point.
Who Are Die-Cast Models For?
These models are for collectors, not builders. There's no assembly — the engine arrives pre-built and ready for display. The appeal is in the scale accuracy, the paint quality, and the sheer impressiveness of a V-12 or 16-cylinder engine rendered in miniature.
They also work beautifully as gifts for anyone who works in or appreciates heavy industry, marine engineering, or large-scale diesel engines.
Displaying Your Model
These Caterpillar models are dimensionally accurate enough to be displayed with appropriate-scale vehicles. The 1:25 models fit G Scale model railroading flatcars. The 1:12 C32B Marine Engine makes an outstanding desk centerpiece in its own right.
