$500 math question on extending ball mount shank

For every inch I extend ball mount shank how much additional force (psi, torque, etc) will be generated on hitch receiver? Any rule of thumbs or formulas? Was hoping people would reply in percentage...

Is this for use with a WD hitch?

If so, then it won't make any difference.

We had a long thread on this a while back. A manufacturer (IIRCC, Torklift) and an engineer (Ron Gratz) were involved.
The result was that when using WD, the effect is nil. If not, then derating comes into play.
The hitch extension that was brought up earlier, is NOT for use with WD, so that would not apply.

Happy reading
