Default Making a softer ride on factory springs is easy

An old member here named Fisherman did something to his factory leaf springs that made a huge difference. He pulled apart each spring pack and painted slip plate on each leaf. It polishes itself as it moves and creates a very slippery surface. His truck rode like a Cadillac. It only got better as it wore in.

On my recent wagoneer build on IFSJA, I put slip plate on all the window lift arm pegs, in the slots under each window including the tailgate and anywhere it would help. The previously stiff windows rolled up and down way easier after putting that stuff on the metal to metal parts. I see a lot of comments on wanting to make the suspension ride softer.
You don't have to remove any leafs either. It really works well. I'm just mentioning it because I am seeing a lot of comments on stiff suspension as I am trying to catch up with the ten year absence I am guilty of.
Fisherman also pegged restoring hard brittle weatherstripping rubber with long term soaking in 303 protectant. He has a few great ideas up his sleeve. He deserves all the credit for those ideas.

Give the spring pack mod a try. It can be done in a weekend and the results are something else. Be sure to follow the directions.

Interesting. I tried Fluid Film and it helped a little. I'm not sure it was worth the mess made applying it, though.

Slip plate is a dry lube. If you apply it to just the upper and lower leafs and then paint the spring pack when assembled, you would never know it is there. No mess, no dirt attraction etc. I put slip plate on the entire face of my snow plow blade. I can say it did not do a darn bit of good. Between metal parts it really shines. I have however sprayed fluid film inside my snow blower and on the plow blade last year, and it rocks for keeping snow from sticking. Problem is it wears away with friction from snow and ice. Not a big deal. Just respray it.
For the leaf springs, Slip plate is a really good long term fix for a rough ride. Made for high friction metal to metal.
I also put fluid film on my satellite dish.

With my motor swap I added a ton of weight to the front which softens it up nicely... my rear is still way over stiff considering I don't haul heavy with it I may start removing leaf springs in the rear to soften it up a bit.
