don't even know if poundage is a word... anyway, is the number normally stamped into the spring anywhere?

according to the pickup truck website they use 900lbs springs on the front (seems a lot!), and 225lbs on the back

I've never checked mine, but it never sits flat on the ground either, it always sits at a funny angle, especially when jacked up.

just hoping theres an easy way to check them

Whip the springs off - if you're lucky it will be written on the top/bottm or carved it. If not then you'll need a spring dyno (Procomp on here has one).

hopefully they're written on there then i thought they would always be stamped on or something.
the guy i got them from told me they were all 300lbs, but i'm not convinced

You don't need a spring dyno, all you need is a bathroom scales and some safe way of compressing the spring on it, and a way of measuring it while you are doing that.

Measure the free length, then compress it by an inch if possible, or whatever you can, measure it in the compressed length.

If it was compressed 1/2 inch, and the scale reas 200lbs, then that would be a 400lb spring

I SAID A SAFE WAY OF COMPRESSING AND MEASURING IT!

Pillar drill to compress and bathroom scales to measure force works well. Stick a 10mm bit or some round bar in the chuck too to stop the spring flying out if it slips

If you can hang on a bit I've a way of calculating a spring's rate by measuring it. Be tomorrow though?
