In the 90…100 horsepower class, Ursus had offered the H-series of Turkish origin. In 2015, newly developed models were introduced, which were slightly cheaper and more lightly equipped than the H-series. The engine was a 3.4-liter Perkins, compliant with Euro IIIB standards. The powertrain in this series also came from Hattat, and the front axle from Carraro. There were 12+12 gears. The mechanical direction reverser was positioned beneath the steering wheel. The power lift was standard, as were the electrically hydraulically operated four-wheel drive, differential lock, and four-wheel drive engagement. The lifting capacity was 4,400 kg. Four hydraulic blocks were standard. Air conditioning was an optional extra. In Poland, Ursus offered a warranty of 4 years or 4,000 hours.

At the end of 2016, the 110-horsepower C-3110 equipped with a 4.4-liter Perkins engine was introduced. It had a 24+24 gearbox. The cab roof was made lower at the request of the domestic market by rearranging the ventilation components. The series also included the C-3120 HL equipped with a 3.6-liter Deutz engine, but possibly its production remained limited to prototypes.

The C-3105 introduced in 2017 corresponded in some respects to models of the smaller series, such as the C-380 K. The series also included the C-3120 equipped with a 3.6-liter Deutz engine and later the slightly more powerful C-3130. These had stage IV emission level engines and a ZF 16+16 gearbox.
