Rear leaf springs

I know I'm late, but that was an interesting comment about crossbows. I don't know about the modern crossbows resembling the vikings crossbows. I though they were different from what I see in this exampleexample

A true spring expert can offer wise hints to allow for stable weight capacity without turning an empty tow rig into a buckboard. Fatigued metal is metal prone to crack. And I am convinced like with so much other stuff a new vehicle manufacturer does not put maximum effort into obtaining maximum performance (including comfort) and lifespan.

Under further inspection it is evident that the springs are flattening out. I have been checking into rear springs and I found out that my 250 comes with the same springs as a single wheel 350. these would be 3000# springs. The 350 dually comes with a 3300# spring. There is also a 4400# spring but I am pretty sure my wife would not approve while touring around empty. I am going to go with the 3300# spring. I would like to thank most of you for your input.

They will sag over time
Airbags will protect them to a degree
Re-Arch doesn't last as long as Re-Place
It's possible to add a leaf (leif?) to restore height and capacity.

Questions: Do you un-load your truck when stopping overnight, when you don't have to un-hitch? It helps to take that overnight static load off.

And, what is the Pin Weight of your Fiver? I ask because I know pin weight improves stability, but it seems some have more than they need. I notice when camping that some similar-sized fivers put a lot more weight down onto similar trucks than others do.

We had sagging rear springs on an old Class C. Went to a spring shop and talked options:

1. Replace with new springs, too expensive.
2. Re-arch the OEM springs, shop said it wouldn't hold long enough to be helpful
3. Add a "repair leaf" to the existing springs, this is what we did.

Repair Leaf is nothing but a length of spring material. Thickness according to how much lift wanted. Width to match existing leaves. Needs to be cut to length and punched/drilled for center bolt.

Since I bought the parts (repair leaves, new center bolts, new axle U-bolts) and installed myself, I didn't have the benefit of their experience. This may not happen to you, but in our case, the rear ended up slightly higher than level. That cut down on tail-dragging which was nice, but it also meant we had to block the front up about 2" to be level on a level campsite. Pickup truck doesn't have that issue, and you might be happy starting out a little high.

Look at Airbags as well to help with the towing. Allows you to level your truck while towing too.

Man, can't slip anything past you guys. :)

Yes, Leif Ericsson invented them & they were commonly used on the Longships as the original prototype to the modern crossbow.
