Don't get me wrong , I would love to use them on my Stock customers cars, I've inquired about them as recently as earlier this year. but here is where the "East Coast vs West Coast" rule books come into play , A matter of interpretation .
I won't risk a customers DQ for what is most likely a negligible gain over a bushing.

That is crazy Tom!
NHRA Tech needs to correct their interpretation of a heim end and spherical bearing.

A heim end is not a spherical bearing; the heim end contains a spherical bearing and all heim ends are threaded and adjustable.

The Global West bars are identical in form and fit and function as the OEM bars and not adjustable. The only difference is it has a solid bushing at one end and a spherical bearing contained at the other end.

Since needle bearings in lieu of bushings are allowed as a replacement to front lower and upper control arms, what is the difference?
