Levelling with Future Plan to Lift

I've been reading and searching this forum for about a full week now and have come from a complete noob to having a little bit of knowledge (stress on the little). I've pretty much decided to go with the adjustable 5100s set at 1.75 to level things out for the time being. My questions are in regards to lifting it a bit more at a later date with a coil. From what I can gather I can do an OME 885 to achieve about a 2.5" lift with a TSB rear leaf and have things level (please let me know if that is correct). My questions are:

What do I set the front 5100s at to achieve the 2.5" lift on the front? 0.85?

I'm assuming I will need UCAs and longer brake lines?

Is there anything else that I've overlooked?

2011 DCLB TRD Sport
Stock 17" sport rims
P265/65/R17
NO TSB leaf

My apologies if this is redundant for most of you but I've definitely out time into reading the forum. Thanks.

 

For the front, if I'm not mistaken, you will set the 5100's at 0" and the OME spring will give you your 2.5" of lift. In the rear you will need a 1.5" AAL if you have no TSB spring. With TSB you will still need some lift in the rear. Mine came with the extra spring in the rear and my 5100's set at 1.75" pretty much leveled the truck. If I went to 2.5" I would probably need 1.5" in the rear to be level.

Oh yeah, you will probably need new UCAs. Typically around 2.5" is when caster becomes an issue. Some people get away with not needing it. You shouldn't need longer brake lines at 2.5".

 

Ok guys I'm.lifting my 07 sr5 bilstien 5100s and fox 3 inch rear long aal dif drop spacer skid plate spacer drop carrier bearing spacer sway bar drop brackets I know I need new brake lines and haven't heard much about proportioning valve will look into and the e brake extensions?. Going cooper atp lr e 265 75 16 on stocks for now my real question is can I put the 5100s on there stock hight or even line 1 1.75 and put.2 inch leveling lift spacers on top to help give them more extension and keep my stock ucas thanks any opinion at this point really helps

 

Thanks for the reply. You've answered everything. I did some more reading today and you are correct that the OME 885s will lift it by 2.5". Looks like 884s will lift it 2.0". Anxious to get the 5100s on and see how it looks levelled at 1.75".
