As long as its a K10 the springs will swap right over. The 3/4 tons and up had the longer rear springs that wouldn't work on a K5.

The rear springs on the K5 and the K10 should measure out to 52". The front springs on k5's, K10's, K20's and K30's are all the same length, they just hold different wieghts.

Just make sure you go out and buy 16 new u-bolts. You don't want to reuse the old ones.
