Susp: heavy half to regular half, should I convert it? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

INSIDIOUS '86 · 02-01-2014, 02:27 PM

So my stepside has the heavy half susp on it and I was thinking of converting it to regular half ton. It has the long 3/4 leafs in back and the heavy one tons up front. I was going to do a 3-4 drop on it and figured I may as well get rid of the stiff susp and make it a better ride. By getting some 1/2 ton long bed springs and doing four per side and cut half ton coils up front. In the meantime adding a swaybar and doing the castor mod.

Being a heavy half stepside would that be desirable to keep on the truck as far as value or will people value the ride quality more?

How many leaf springs in the rear spring pack?

If youre going to lower it then I would change out to the c10 suspension and make the truck ride better

I don't see the "Heavy Half" thing being a desired option.
I'm not sure what GM even offered as a change to the regular 1/2-ton trucks.
I thought it was just a marketing thing back in the day.

I would keep the 56" rear springs.
Do a flip kit and a 4/6 drop.
I was never a fan of the shackle/hanger 4" drop.

Yah really for the engine and emmissions Benifit. Although the original 454 was lost for it long ago. I know for fact it was a heavy half but it's kinda moot on a stepside haha

i have managed to get about half a ton in my short bed step side c10. thats really trying. 5 leafs handle that just fine. i have 3 now and it did just yesterday with like 800. really its a half ton so you dont need to put 2000 lbs of gravel in it. i would keep the coils and drop the leaf pack to 4 or 5. i know my crew cab just hops the rear over speed bumps. i dont think that is what people look for haha
