1st gen rear suspension getting the most out of stock travel?

Hello! New on here and this is my first post, i have a 2001 TRD off-road tacoma that is MT up front on Fox 2.5 factory coil overs, with JBA UCA’s. (picture below)


My current setup in the back is 5100’s with stock leafs. I’ve found the rear end can’t quite keep up on washboard and rougher roads at the speed i like to go. Been thinking about getting the Deaver 8 leaf progressive leaf pack, paired with these. https://accutuneoffroad.com/product...ries-remote-reservoir-8-1-travel-cd-adjuster/

Would this be worth it? I’ve looked at the the total chaos 2.0 rear shock mounting kit but not super interested in welding something to my frame. Any suggestions would be greatly appreciated!

 

Although I have not any direct experience I am skeptical that a leaf spring solid axle suspension will ever be as good as a double wishbone independent suspension as far as high speed handling and comfort goes.

However, increasing travel, changing leaf spring characteristics, and changing shock valving, could likely help.

Also note that much of what you do could decrease the with doing truck stuff. For example, softening up the rear suspension could help it deal with washboards but at the same decrease your ability to carry a heavy payload.
