Chevy built two very different trucks in the 1955 model year. The early 1955 run, called 1955 1st series, was the last of the Advance-Design trucks. Midyear, Chevrolet launched an all-new truck line called Task Force, known as the 1955 2nd series. The change brought new styling and key mechanical upgrades.
1955 1st series - what to look for:
Carryover Advance-Design body from 1947-1954 with rounded cab and separate fenders
One-piece curved windshield and revised 1954-style grille carried into early 1955
Inline six power and 6-volt electrics typical of the AD era
Built only for a short early-1955 window before the redesign arrived
These traits reflect the 1954 updates that continued briefly into 1955 1st series production.
1955 2nd series - what changed:
All-new Task Force styling with flatter hood, integrated fenders, and wraparound windshield
12-volt electrical system became standard
First-time optional small-block V8 (265) alongside the inline sixes
New trim and bed options, including the modernized look that set the tone for 1956-1959
These updates debuted midyear 1955 and marked Chevy's first major truck redesign since 1947.
Bottom line:
1st series = last Advance-Design carryover
2nd series = new Task Force design with wraparound glass, 12-volt system, and available V8
This midyear split is why you'll see two very different 1955 Chevrolets wearing the same model year.
