Avanti R3 HD Lowers?

[mfg]

Interesting that Studebaker did not use heavy duty LOWER control arms on their R3-4 powered cars.  (grease fittings on inner shafts instead of rubber)

They no doubt stocked these HD lower arms from left over '51-'52 production.

Actually, the easy answer is that they would have had to use the pre'58 front shock absorber setup, and they no doubt did not want to go back to that.

The above reminds me of the '64 square light I once owned, which I installed a 'full set' (4) of HD front suspension control arms on...

It took awhile to grease that front end..There was 26 grease fittings in total if I remember right!!

I imagine they did the top as it is way more prone to wear out as it rotates about twice as far as the lower during deflection.

The for aft loading results in more deflection than what is seen on the lower arm due to the difference in spread of the bushings.
