what safety factor are they using in their advertisement? that alone makes a huge difference.

i'll say it again, jj or spohn unless its a phb, watts or sway bar link.


edit------

acutally i found it. here it is from aurora's site;

"Is there a safety factor included in the ultimate radial static load capacity?
You should assume that there is no safety factor. The bearing will fail at the advertised load."

and from qa1;

"Note that QA1's cataloged radial load ratings include a safety factor"

both then go on to say that adding a zerk will lower that rating. so, even if the qa1 is a 2:1 which isnt that conservative, then they are about the same.
