These joints are not under heavy load in a steering tierod application and have a static load rating of over 28,000 pounds.

Please post up one picture of a failed QA1 hiem used in a tiered application.

They are trail tested, tried and true, made in America joints.
I think this is a discussion of best practice vs. practicality. I think we all agree that a best practice and for the most extreme circumstances, mounting a rod end/heim joint in double sheer is ideal. However, as Frank pointed out, in this particular application (tie rod/drag link), the forces applied should not reach a point that would cause failure. If I were in a KOH style custom buggy running 44's and hydro steering on my Dana60 then I may think differently!

Yes, I am being an enginerd with my comments and they are in no way to be considered an attack or criticism.

Although I do think that going with a ball joint instead of a spherical joint to ball joint adapter (?) is kind of an expensive way of doing what a ball joint does already.

But I guess if it's to stay with a standard thread-size for the weld-in bung then it's a solution to a problem!

Not aken as criticism...but tierods end are more expensive and there's no tube adapter available for the LR tierod end. I could thread a piece of solid tube, but a 4" pice of solid tube is WAYYYYYYYYYY expensive.

I run these on my full hydro steering on my D2..
