only 3 settings for 5100?

I just got a set of 5100 shocks for my 02 tacoma and from the photos and install it show 4 adjustment grooves meaning first setting 0, second setting .85, third setting 1.25, and forth setting 2.5.
But my shocks only have 3 grooves not 4...so what are the settings?

 

0, 1.25 & 2.5 the 1st gens only have 3.

 

2nd gen 5100's have four, 1st gens only have three.

• Bottom=0" lift
• Middle setting is disputed on how much lift it gives but it is close to 1"
• Top setting gives 2.5"

 

Curse these slow fingers

 

Ok. I didnt know that when i ordered them. I guess my research wasnt deep enough.
I got a one inch lift shackle for the back so i hope with the 1.25 setting in the front and an inch in the back will look good....i would hate to have a bro lean haha

 

I heard/read you can get the ones with 4 setting it was a specific vendor can't remember who at the moment?
