    Have a 2011 DC OR PR, Want to put some 5100's on all 4 corners and a 1 1/2" AAL from toyotec. I have the TSB 4 leaf pack. Gonna set the 5100's @ 1.75. Will I need a diff drop, Shims, or UCA's? I would life to keep it as simple as possible without messing with the stock set up too much. Pics of this set up would be nice as well.

    UCAs-Prolly Not. The other two- Maybe...Maybe not. These trucks all seem to have their own thing when it comes to suspension.

    You shouldn't need any of those for a 1.75" lift.

    Definitely don't put any shims in until you experience driveline vibration - then put them in only to correct it.

    Here's the best article on diagnosing and solving driveline vibration:

    I have 5100's set at 1.75 and a 1.5 aal, no diff drop, UCA's or shims. I do have a slight vibration from take off, so I do wish I did shims at the same time.
    If you already have the TSB leaf pack and then goin to add a 1.5 aal, I would install shims and drive shaft carrier bearing drop too. With it going to be TSB + AAL, you might want to consider the 5100's set at 2.5 aswell.
    Though aftermarket UCA arn't needed at 1.75, they would def help with getting alittle better feel through the steering wheel and to get your alignment exactly where it needs to be. My alignment is in-spec but not dead on like it would be with UCA.
    As Brunes said... each truck acts alittle different than another.
