The modernized 5-Star came as the successor to the UB model in 1957. The engine was the same 4.6-liter as in its predecessor, alongside which a 5.5-liter diesel was introduced. Later, the 3.4-liter model 445 was also updated and included in the same series under the name 4-Star. Mainly the appearance was renewed, and the hydraulics were improved with the addition of the Tel-O-Flow load-sensing system.

The base model once again came without any equipment. The Super model included standard features such as the Ampli-Torc quick power take-off, a three-point hitch, external hydraulics, power steering, and larger fenders.

In 1960, the M-5 was presented as the successor to the 5-Star, featuring an angular design similar to that of the larger G-VI model. In the M-5, both the gasoline and LPG engines increased to 5.5 liters. There was also a very rare four-wheel-drive version of the M-5, called the M-504.
