Front coil spring ?
Just wondering if anybody know the spring rate of stock IROC coil off the top of there head?
I don't have a third gen, but I do have a set of coils out of my old 86 iroc.

550 is it? I figured they would be alot higher rate than that. Guess I'm better of with my stock S10 coils at that rate... LOL

Moog sells replacement springs at like $50 a pop and you can get 700 lb/in rates and other companies sell similarly priced springs with even higher rates. Unless your springs are super low mileage (<50k miles) I'd sell them to some kid trying to do a v8 swap on the cheap or scrap them. Not a lot of benefit/ demand to old worn out springs when you can get two brand new ones and some stickers for around $100

I've been told some stock S10 coils are upwards of 700lb/in. (707 and 748 to be exact).
I'll probably just use my stock coils and cut 'em to get the ride height I want.
Unless F bodies have totally junk springs, I can't see 'em sagging alot. I'm sure they will sag some and lose some strength, but not alot.
My old 93 C1500 has 454+ thousand miles on it and it might sit an inch lower than stock, (not counting the lowering spindles). Granted it's not a corner carver or anything close, but it does have twice the miles on it that a normal high milage car would have. LOL
That 100 bucks will buy me a roll pan..... LOL

Actually, those are the rates out of the Moog catalog for the 5662 and 5664 springs, which do indeed happen to fit S trucks. (and F bodies, and A & G bodies, and prolly a whole lot more besides) But they're not "stock" in anything.
The IROCs usually measured nearer 450 by the dinking-around method; (set heavy stuff on it and see what happened) but after however many years, who knows how much they'd lost.

No, not exactly...

Good little read here;

Found that while searching for how to count active coils.

Re: Front coil spring ?
But according to the number the S10 coils would be great cheap lowering coils for an F body.
