Longbed rear lift question

Hello everyone, for those that have lifted their longbed with a complete leaf spring, did you get the amount advertised you would achieve? While shopping for Deaver j66’s it states a 1-1.5 lift but for longbeds it could be less due to vehicle weight and you may have to purchase the higher rated leaf pack to achieve the desired hight. I have been searching the thread to see if this specific question has been asked asked and could not find anything. Sorry if I’m beating a dead horse.

 

I have medium Dakar pack. Got the advertised lift.
