Longer ball joint.......

[henrys57wagon]

In the 80's I made a 1"(I think or 1-1/2) aluminum upper ball joint spacer to raise the upper A arm

Putting a spacer between the upper ball joint and control arm dosen't really do anything other than allow the suspension to droop more. A longer ball joint stud may actually change the arc of the upper arm. ---Trevor

Hasn't been legal in Stock since the Junior Stock days.
The longer stud ball joints seem to fall into the "manufacturer's tolerance" category with NHRA..

Do you mean by droop that the front end sits lower than without the spacers?
Like many things that are not legal, it is only illegal when you are caught.

I was under the belief that the long upper ball joint helps put more positive camber in the front end so the front tires are not running on the inside edge possibly scrubbing also.
Might help w more positive caster, but that I'm not so sure of.

Droop is the amount the front suspension will hang down in a wheelie situation. The longer ball joints help maintain your camber in droop. The balljoint extenders alluded to were easy to spot poorly manufactued and frequently broke , simple to outlaw.---Trevor

tj I agree that the piss pour quality of some of the cast spacers is the reason they outlawed them. My pieces were made from solid 6061 aluminum and were used for 10 years and still good when removed. They are still sold and guys building gasser style cars use them.

Sorry I should have said thanks for the info on droop'd front end. Henry
