    I've searched and read the forums, and while I've found a lot of useful information, I haven't been able to find the answers to my questions. I'm new to the truck modding world, so if these questions seem newbish, I apologize in advance.

    1.). I asked the dealer when I bought the truck if all TSBs had been addressed. He assured me that being a Toyota certified preowned, all TSBs were taken care of. So question number one is...is there a way to tell by looking if my truck has had the read leaf spring TSB performed? What should I see if it is "fixed" and what shouldn't I see if it is not?

    2.). If the leaf springs are up to date (and I think they are), it seems the back of my truck is 1 - 1 1/2 inches higher than the front. What can I do to level things out?

    Thanks for all your help!

    1. If the TSB was performed you will have 3 leafs plus an overload on each side
    2. Bilstein 5100's at 1.75" gets you pretty level with the spring TSB.
    3. These are both very common questions and you may want to try a quick search next time.

    Thanks for your input...if you'll notice, I mentioned that I DID in fact search first and could not locate the answers.

    Thank you though for you answers.

    if you ever want to tow anything,u may not want to level it of the front end will be way higher than the back (which if you ask me looks stupid, though i have met some people who like it.)

    also i have been told by a fellow TW user, that leveling can drastically decrease your MPG. (i dont know for a fact but thats why i did not level mine)

    Above the poster said I should see three (plus an overload)...I DO see three...but could you clarify what an overload is? Again, I'm new to suspension talk, so please bear with me.

    The first part of what esimmons said is true, regarding towing. The 2nd part about gas mileage, not true at all unless you put bigger tires on in addition to levling, but leveling alone won't affect your gas mileage.
