International K and KB series

Models

The K models progress from 1 to 14 based upon the load capacity (K1 = half ton, K2 = 3/4 ton, K3 = 1 ton, etc.).

There are no K-9 or K-13 model trucks.

Light duty

Few differences exist between K-1 and K-2 models as they share most of their mechanical and chassis components. The rear axles in these two models are supported by a single roller bearing. Their differences in load rating are due to the K-2's stronger suspension.

The K-3 has a heavier frame, larger brakes, and rear axles supported by two roller bearings on a free floating rear end. The heavier duty K-4 has artillery-style wheels.

Heavy duty

The heavy duty K6 and larger use a center hinged butterfly hood rather than the rear hinged hood of the smaller trucks.

K6 and K7 share the same hood, fenders, and grill and use the smaller Blue Diamond engines.

K8 to K11 have a larger hood, fenders, and grill with fewer, but wider, grill bars. They use the larger FAB, Red, or RD series engines depending upon model year.

K12 has a longer hood to accommodate the larger Continental engine. They can either have the rounded nose common to the KB8 and larger or a flat nose grill.

K14 has flat top fenders rather than the rounded top of the smaller sizes.

Styling

The style of the truck involved headlamps that were integrated into the fenders. The hood opens alligator style. Heavy duty models (K6 and above) carried over the D-series cab and high crowned fenders.

А KB-5 truck with a King Midget on a flatbed

For the KB-1 thru KB-5, chrome "wings" were added on the sides of the grill, a wrap-around chrome piece on the front hood, a hood ornament and chrome lettering indicating the model designation below the International nameplate on each side of the hood. For the KB-6 and larger trucks, the only external changes were that the Triple Diamond badge was moved to the top of the grille chrome-work, and the model designations were added to the hood-side chrome trim.
