Do lower control arm reinforcement plates actually work?

Well the straps will keep the ends from spreading apart, but they don't help the stiffness of the whole arm.

Even with the plates the LCA's are pretty much still open on both ends, and the holes are pretty substantial. I drive on gravel roads a decent amount and haven't really had any buildup. The plates are easy to make too if you don't want to pay for them, although for the price they get most places it's worth it for the time spent, especially if you bundle them in when you order all your other suspension rebuild parts so you're not paying shipping on just the plates.

I run 1" straps across the openings in the arm. Same strength, less weight. One under the sway bar mount to resist mount flexing the LCA.

The one under the strut rod bracket is probably better served between the bushing and middle of the LCA. I put it on the end cause I had another Mopar that was bent there.

Then I run the strap across the back.
