K10 Leafs

[swissarmychainsaw]

Hey Guys, I have a "new to me" 73 burb that is fairly fugly, but I really like it.
Taken the family on a road trip and camping and it's great.

The Suspension however could use a little love.

I plan on doing the "front end", tie rods, pitman and idler, and probably ball joints while I'm there. Hell ok, brakes too.
I don't know the mileage but I plan on driving this thing.

What should I do to "refresh" the suspension. It's not a horrible ride, but
hitting large bumps on the highway is a bit more exiting that it should be.
There is likely a small lift on this truck already as the rear leafs have spacer blocks in them. How long will a leaf spring last?

What I would like is a nice plush ride, and yeah I get that 4 leafs are limited!

Was looking at kits from ORD, but I wanted to ask here, and see what yall like.
