Savvy aluminum control arms strength?

Last year when I decided to lift my 03 TJ, after a lot of research and reading on this forum, I decided to go with a 3" suspension kit from Savvy. When I ordered it from Gerald, they were running a promotion as I recall and they upgraded my kit with the JJ fully adjustable aluminum control arms for no charge. They have been installed for almost a year and so far I love them.

Today while talking to a guy at a local jeep shop about the upcoming tummy tuck I have planned, he asked about adjustable control arms and I told him what I have. He said something to the effect of "Oh you fell for that" and then proceed to tell me that aluminum CA's are have no place on a Jeep and that the threads will pull out causing them to fail. Do I have anything to be concerned about or is he just trying to sell me their own brand of control arms?

Don't be concerned, he's just trying to sell you something or he is misinformed.

I'm sure all those airplane parts that are made from aluminum are just waiting to fail

If you dont keep the jam nut tight you can ruin the threads. So in other words, no as long as you make sure the jam nut is tight

His dad should've pulled out but he failed. Hence the ******* you interacted with.

So they've been on your Jeep for almost a year & you're worried about what someone else thinks about them?

You'll be fine as long as that jam nut is nice and tight. I will agree that 2 inch 7075 links are a bit overkill for short arms. But you'll be fine with that set up. And i would go elsewhere if that guy doesn't believe in 7075 links. Those things are tough stuff cause they are a memory material and won't bend as easy.

I suspect with as many of those that are out there, if the propensity for failure actually existed, it would have shown up by now. As long as you keep the jam nuts tight and don't let the joint hammer the threads, you'll be fine.

Ask him if he knows what grade the arms are.

Guys thanks for the input. I've spent a lot of time reading these forums and I don't recall ever seeing a trend of aluminum CA's failing but I guess I just wanted to make sure I've not overlooked something. I've got marks on all the jam nuts so I can quickly see if one has moved from the last time I tightened them and will continue to make sure the jam nut are tight.

I sure don't like it when one manufacturer bad mouths another product. Like I said, I love the products I've purchased from Savvy and even placed another order with them tonight for more parts for my TT project.
