74 Weld Billet Upper Control Arms (Toyota Tacoma, FJ Cruiser, 4Runner)

by 74Weld

These Billet Aluminum UCA's from 74 Weld are unique because they have been manufactured out of Billet Aluminum on a 5th axis machine. The uni-ball cup follows the same geometry that you would get out of a chromoly steel after-market UCA.

Here's what makes them special per Weld 74, "There are lots of companies that make aluminum upper why make them? Every aluminum arm I’ve seen places the uniball on plane with the arm. They do this because machining the uniball at the correct angle is difficult and requires either multiple ops and fixtures or a 5 axis. We try not to make what everyone else is it better or don’t do it..."
