So, I have a 1976 K10. And the person that I bought if from didn't know much about the truck. I know that it has a lift on it and was wondering if anyone could help me with identifying the springs, etc... The rear shocks are the what the stock configuration requires (I measured them) but they are fully extended at the top of the shock travel and it rides like crap and clunks like crazy when going over bumps. I would like to have as good of a ride as I can get...knowing that it's a K10 and it's not going to ride near as nice as it's C10 counterparts.

The front springs look relatively flat which makes me think 2.5" / 3" lift BUT the rear appears to have 4" tall blocks.

That said, a stock truck will measure approx 8.5" between the top of the front axle tube and the bottom of the frame. Any difference is the amount of lift.

Ex: measurement is 14.5"
14.5" (actual) - 8.5" (stock) = 6" (lift)

Ahh...I'll go out and measure things. That is awesome information! Thank you so much nvrenuf!! I should have posted a picture of the truck and how it sits.
I got 10" in the front. So, 1.5" of lift...that sounds kinda small.

It will probably ride much better with some appropriately sized shocks. I agree, it looks like a 4" lift

By appropriate sized…Something along the line’s of 21.5” extended? Trying to get some ideas on what others are using.

Are you measuring from the top of the axle tube or the top of the springs, or maybe the edge of the diff housing? The way it sits looks to be about 3" to me

BTW my wife says 1.5" is just right

I agree, not a ton of lift but definitely more than 1.5”.

I’m using Tuff country shocks from ORD. They have a chart that tells you what shock to use for a certain amount of lift. You can also do it the right way and disconnect the current shocks, measure the length at rest, then lift the truck by the frame until the axles are just dead hanging with no shock attached. Measure it again and just call a shock manufacturer with those numbers. They can give you a shock recommendation based on those measurements.
