The Cub was derived from the Terrier truck chassis, and was originally built at Leyland's Scottish plant in Bathgate. It was available in three variants - CU335, CU385 and CU435, the number in each indicating the wheelbase length in centimetres. It was usually fitted with Leyland's 5.7-litre 6.98NV engine, though the derated 6.98DV was also an option.
Most Cubs were built for local authorities and the welfare sector, and thus carried bodywork by Wadham Stringer of Hampshire or Reeve Burgess of Derbyshire. However, Lothian Regional Transport took 18 CU435s with Duple Dominant bodies in 1981, while the West Yorkshire Passenger Transport Executive bought 15 with Optare bodies in 1986. There were also four Reeve Burgess-bodied Cubs for Southdown Motor Services in 1983/84, and two for Greater Manchester PTE in 1985.
