9/1 Leaf Spring - Ride Quality Question
« on: February 22, 2011, 12:33:03 pm »
Hi,

I have a 1984 Chevy K30 DRW that I hope to convert to a utility body.  It's in need of new rear springs and I was curious if anyone has any experience with the ride quality differences  between 3950 lbs or 4650 lbs 9/1 springs.  

I appreciate any opinions.

Thanks.

Welcome from Arizona. These trucks never rode too smooth from the factory, especially the 1 Tons. I'm sure someone will pipe up with preferences.

If you are adding a utility body I would size it accordingly.  with extra weight you won't notice it.

Thank you for the replies. The axles are Dana 60 front and 14 Bolt rear. I'm not sure if it's possible, but with the heavy springs, if I hit a bump in the road I'd rather it didn't sound like a small explosion.  I think the empty body is 1200-1300 pounds or so.

     Like capt. said, you should estimate the weight of the utility body with what you are going to carry and talk to a local spring shop, they will calulate what springs to run and you wont even feel it with enough weight in back.

How much of a load are the boxes hauling?  I know they'll hold quite a bit and the weight adds up fast.

Maybe an overload spring setup?
