Lca stiffening plates

[fk5aar]

I am rebuilding a 70rt w 383 bored .30 over. The concept of the stiffening plates seems very smart but since my motor is not really overkill or crazy powerful would they help out a lot? I got the car disassembled so I never drove it first. Please let me know what you guys think thanks.

I did it to my lower control arms in my 71 Barracuda, however, I have not drove it so I can't really say how much it helps. As easy as they are to weld in, it seemed like the right thing to do. I have to say, I did a lot of other mods to the chassis and upgrades to the suspension so it made sense to do the LCAs as well. Rod

I have installed them on my last two builds.. My duster and cuda. I don't know if there is a ton of difference but for the 30 bucks I feel its worth it. Usually they seems to drive a ton better as when I do a car its a complete build so all new tires, ball joints, tie rods, steering box, control arm bushings, new t bars/leaf springs.. so usually feel like brand new car on the first drive. They look nice installed and welds smoothed out

My suspension in my 71 Barracuda. Can't see the stiffing plates, but they are there.

Definitely worth installing in conjunction with new ball joints and other new front end parts. The plates really tighten up the front end flex for an inexpensive price.
If you choose to install, I clamped the two sides of the lower control arms together a little tighter, making sure that the torsion bar arm still pivoted freely. This is where a lot of the looseness takes place on the LCA. Then weld on the support plates.
