Which C20 rear coil springs?
 

I'm looking at my options on rock auto for getting some coil springs, and I'd like some input from those who are familiar with these different springs about which I should get.

Here's the ones I'm considering with the load rates:
ACDELCO 45H3018 950
ACDELCO 45H3075 1335
ACDELCO 45H2011 1700
ACDELCO 45H2012 2900

This is for my work truck that regularly carries 1,000-2,000lbs of tools and chemical.

I'm the type of guy that likes to over build, but I'm wondering if the 2900 pound spring is too much and maybe I should stick with the 1335 or 1700. Thoughts?

If you use it...bag it. You can air up when need and lighten the springs when empty for a nicer ride. I have Ride Rights on my 1 ton and it helps ride and load.
