went and had a look at the australian ARB site. Just as lamea$$ as the USA one... sheesh... If you go under "catalogue" then USA then look left you'll see a small mention of vehicle specific info. There is a pdf file for the 80 but with very little info. However, this is what it says:

---------
Model Location Description Type Lift Quantity Part No.
80 Series Front Stock/Light Load (0-110lbs) Spring 2.0" 2 OME851
Shock 2 *N73/N70
80 Series Front Heavy Load (110-250lbs) Spring 2.0" 2 OME850
Shock 2 N73
------------

so it shows a difference in weight between the 851 and 850, but the same lift. I take that to mean that the heavy 850 will provide 2" of lift *after* it's been loaded with the 110-250 lbs...

They also mention the 850J but did not include the lift or length for those... sheesh...
