Do I have the TSB spring upgrade already?

Just picked up a 2012 DCSB and was looking into the Billy 5100 upgrade to raise up the front some / level.

Kept seeing reference to TSB in regards to the rear springs. After some research it seems this was an AAL that was added to three leaf spring packs to add some height. I took at look at my springs during lunch and see that I have the 4 leaf spring pack (3 main and a "helper").

Does this mean I have what would be considered a "TSB updated" spring pack? if so, would I be able to put 5100's on the front at 1.75" and 5100's on the rear and be good to go?

First toyota as I came from the jeep world - trying to learn a whole different system is fun and hectic.

yep 4 leafs is the tsb pack.

 

Finslayer thanks for asking the question fixer 5000 thank you for the answer. Be well guys, Jake

 

To get a better idea, measure from center of hub to fender, with the knowledge that @ 1.75" you will be raising the front by around +/- 2", and compare that to what you have in the rear.

I just got mine set to 1.75" with the TSB springs (new ones), and I'm slightly nose high. I'm looking into getting an AAL now. I want to have 1"- 1.5" above my front.

Some guys have done this, and have had perfectly level trucks as well.
