How many notches on older 5100s?

I have the older 5100s which can be set to 0, .85, 1.75 and 2.5. A while ago I had my LD install the rear TSB, 5100s all the way around and set the front Billies to what I thought was 1.75". My truck is currently at a 4x4 shop having the 1.5" AAL installed and I was also going to have the front Billies set to 2.5" however the mechanic called and indicated the shocks were already set on the highest setting which he mentioned was the third notch. I think he is right however I wanted to clarify before I go and pick it up. With the TSB, the rear end sat aproximately .5" higher than the front. I instructed the mechanic to install the rear AAL regardless. Thanks in advance for any clarification on the number of notches.

Cheers

 

Having them already set at 1.75,The collar is covering up the fourth ring.

 

I didn't realize there were older sets of 5100's, but if your can be set to four settings, as you indicated, then the highest setting would be the 4th notch, not the third.

 

Thanks for the heads up. I seemed to recall there were 4 notches for 4 heights but wasn't sure. I am glad my 4x4 shop was wrong as it looks goofy with TSB + AAL in rear and fronts set to 1.75".

Cheers
