4x4 Looking for comfortable ride

[Ben_Yeaton]

Looking for some help with the suspension on my boss' truck. I've only owned 2wd C10's so this is a bit out of my league.

Truck is a '66 Long bed sitting on a later 4x4 chassis. 350, th400, geared very well for the 33x12.5's it sits on. Not positive on the frame details but I gather it's mid 80's? Looks like a 3/4 ton chassis as there are 8 leafs in rear?
Maybe pics will tell the story.

Truck obviously rides very rigid and it's only used as a daily locally on the street, never abused or worked hard. The most it will ever tow is a jet ski trailer. He is looking for much more comfort in the ride. I have mentioned just buying a stock 2wd truck to enjoy but this truck has been in the family and has sentiment.

What are the options at this point? Are there aftermarket leaf packs to swap in that ride very soft? Should I begin removing leafs? All suggestions / real world experience welcome (other than swap to a 2wd chassis lol).

Thanks in advance!
