Stovebolt.com Forums The Shop Area Driveline Identify if leaf springs are original or drop

Hello,

I am looking to replace my front and rear leaf springs in my 54 3100 but are not sure if the current ones are stock height. The drop was done before I got it. It has a front drop axel installed and4” or 5” lowering blocks in the rear. Any suggestion on how to determine? I want to keep it how it sits currently but with new leafs and mounting hardware.

Here's a couple pics of new stock front springs on my '52, also shows how much the 216 settles them down after installation. Wouldn't think '54 would look much different. I could be wrong.

Skooter's pics look just like the new springs I got for my 54 3100 from St. Louis Spring several years ago.

Jimmy, do you have a source for those specs? I have been looking for that info for my 58 for a while. Maybe your source has some newer info too?

Are you having issues with the springs that you have now?

Edit: I think you were asking the OP if he had spring issues.

@jimgmc. Thank you for the info. I will look for the numbers



@52Carl I am not having any spring issues now. Was just trying to update item as I go. The shackles need replaced for sure so I thought I would replace the spring before I had an issue with one of them as well.

Thank you everyone for the replies.

If this were my truck, I would remove the springs from the truck and remove the bushings from the springs and inspect the spring eyes to make sure that the bushings did not wear all the way through and damaged the spring eyes.
If there in no wear there and the springs are not heavily pitted from rust, I would use what you have.
New springs are generally stiff. They are designed to do the work which these trucks were designed to do. Haul heavy loads. You may not like the ride which new springs may provide. I doubt you are planning on hauling much in your truck, judging from its stance in your pics.
