Icon 3 AAL Prorgressive

So I bought this aal along with some tires and rims today.

My question is, what size ubolts do I need for these (didn't come with them)? I am putting them on my 08 Tacoma 4WD.

Second question is.... should I leave the overload leaf on?

Anything else I should be aware of? Thanks.

 

I m pretty sure the stock length u bolts are long enough. I bought aftermarket for mine only cause I wasted to play it safe. But remember thinking that the stock could have worked also.

I left my overload leaf on even tho they say to take it out, I carry heavy shit sometimes for work. I'm not sure if it changes the ride height.

 

I'm running mine with stock ubolts. But mine came with new longer ones too. Initially one of the bolts in the package was wrong. I couldn't use it so that's why I'm running my stock ubolts instead.
