More leaf spring TSB questions

I'm working with the local Toyota shop to apply this TSB to my 2010 TRD Double cab. I stared doing some light hauling and hope this will stiffen up the ride.

The other issue I hope it resolves is the loud bang when I go over deep pot holes or RR tracks, that I hear from the back. These are true whether I'm hauling or not. Any thoughts?

Also, does this TSB give any lift to the truck? And finally, has anyone who has had this done, regretted it afterwards? I just want to know what to expect.

Thanks as always - this is the best Taco board on the web!!!!!

Slightly higher in the back with the TSB. Stiffened the ride a little bit. I like how it rides now then before. I have no regrets.

Prior to the TSB if the bed was full of stuff I would get mad sag. With the extra leaf it helps a lot.

Took the dealer a couple of hours. Dealer was trying to convince me not to get it done because it will stiffen up the ride.

Get her done...
