Help me choose: Lift rear or leave as is

Hello forum,
I just had my Bilsteins installed 2 days ago. I have the front @.85 and I have a Helwig 1.5" AAL. Today, I was given a 1" steel leaf spring block kit with u-bolts, washers, & nuts (NEVER USED & FREE). One of my customers gave it to me because he no longer owns the Tacoma that he bought it for. Should I install this and get more rake or leave it as it is now with only a slight rake? Also, will 1 more inch cause driveline vibes?

Stock height with the LT265/75r16:

After lift kit:

Thanks.

 

So you have the 1.5" AAL installed right now?

 

Looking at the picture doesn't seem like he has the aal on

No matter if it's on or not I like the height it is in the picture

Nevermind saw 2nd picture

 

I say leave it.

 

Just saw the 2nd picture. I say leave it as is. I'd prefer leafs over blocks any day anyways.

 

Yes. It is installed in the 2nd pic. It doesn't look like much but I did take accurate before and after measurements and it's 1.5"s
