These leaf springs came off of my 2007.5 Sierra HD. They were on the truck for a few thousand miles. Some people install them on their 1/2 ton trucks to increase cargo capacity. Or you can use them to replace ageing springs on your 3/4 ton truck. Length should be the same for 1/2 ton and 3/4 ton trucks. Springs are 64" total length.

$150.00

 

would a half ton sit at the same ride height as their half ton springs with these installed, and if not how much higher will the truck sit with these?

 

x2, i would like to know as well

 

I haven't installed 3/4 ton springs on a half ton truck so I can't say for sure. I don't think the arch is different. I know the truck won't sag as much if you load up the bed or connect a heavy trailer. It will take the weight better.
