63” Springs

[tdub209]

Took my little brother on his first junkyard trip today. was able to find a set of 63” springs for my 75/85 k20-k30 hybrid. pretty excited for the spring swap, i just need to order frame hangers and a shackle flip then they’ll be going in.

Those'll definitely be nice and flexy

How do you measure springs?? On the vehicle or off?? Center of bolt hole to center of other???

i have done both. normally go center to center and you can tell. if the number isn’t exact what i’m looking for i know what they’re off of so i have an idea.
example on my truck i have 56” rear leafs and when i measured them they came out to 55” or something but i knew they could only be 56” because the 3/4-1ton trucks had 56” not 52”. then with the 63s they are off newer body style chevys, normally all chevys from 88-newer had 63/64” i measured these exact springs on the truck and they were 62-3/4” center to center bolts. they were off a 04 chevy 1500
