USCT Inner Fender Shock Tower Brace Kit - Fact or Fiction?
When I worked at XV years ago, we developed all the chassis stiffening and tested it all on a four post chassis rig at Multimatic in Canada. When the pieces we made were all put on together, the stiffness of the chassis was on par with modern cars. This meant frame connectors, inner fender braces, lower rad support and Underwood brace. We never made an under hood brace for the A bodies.
After they went out of business, US car tool came out with lightweight versions of what we had and called it their own. They even made a crude copy of one of our videos demonstrating the stiffness with a floor jack...Our parts worked. I’m not sure if any legitimate testing has been done on their version.
