There are a few key differences between C and K Chevys. C-series trucks were produced from 1960 until 1998 and were designed for light duty. The trucks in this series include the Chevy C10, C20, and C30. On the other hand, K-series trucks were produced from 1963 until 1987 and were intended for heavier duty. The models in this series include the Chevy K10, K20, and K30.
One of the main differences between these two series is their suspension. The C-series trucks have a coil spring front suspension while the K-series have leaf springs. This means that the C-series is going to provide a smoother ride quality since coil springs absorb bumps better than leaf springs. However, the leaf springs in the K-series give it better support when carrying heavy loads which is why they’re considered more durable overall.
Another difference between these two truck series is their engines. The engine options for the C-series included small displacement options like a inline six cylinder or V8s that ranged from 200 cubic inches to 350 cubic inches. On the other hand, the engines available for purchase in the K-series were all big block V8s that started at 383 cubic inches and went up to 454 cubic inches. So if you’re looking for more power under the hood, then you’ll want to go with a K-series truck over a C-series truck.
Finally, another difference worth mentioning is their bed size options. The beds available on C-series trucks ranged from six feet to eight feet long while the beds offered on K-series trucks started at six feet and went all way up to 10 feet long! So if you need a longer bed for hauling materials or equipment, then again you’ll want to choose a K-Series truck over a C-Series truck
