Tubular Front control arm kits problems ?

Inexpensive Ebay arms but they had a CPP printed on the box and they came from Classic Performance Parts. They work well and have held up to several road trips over the last few years.

So, you can get the factory upper A arm back on the car? It looks like it shouldn't and I can't figure out why it looks like it has no weight on it. That's how my front end looks on jacks under the front frame.

 

Yes,and that lower control arm jounce bumper should be much closer to the frame, if not actually resting on it with full weight on the lower control arm. If that picture you sent is indeed with all weight on that control arm with the jack underneath, then there must be something binding your suspension, or the spring is caught up somehow. I asked previously if you have stock springs. Have you done anything at all with the springs?

When installing the arms, confirm you are using the jack to raise the lower control arm up to wards the upper to start the threads while the frame is supported by jack stands as well? Just want to make sure we are covering all the obvious stuff here.

knucklebusted, sorry to hear about your experience with the SPC arms. Every car is indeed different, and I have never heard of that problems you experienced, even after a lot of research on the arms, but that is not to say that it couldn't exist! I wasn't offering the SPC arms as the only solution, and clearly, they will not fix what is going on with his car by themselves since there must be something else happening.

 

Hi the springs are 72 454 chevy big block springs. I installed a after market sway bar from opgi as well. the control arm kit I tried installing is from mbm tubular kit.
I will post pics tonight of the kit. Just leaving for work. I'm wondering if the sway bar is causing less control arm travel?

 

I doubt it is the sway bar. It is easy to drop one end link to free it up to prove it isn't. I suspect 454 (heavier than Buick 455) is a big part of the issue. I'm actually amazed you got them in there. Have you had it together with the factory upper control arms?

 

It was not a problem, I used a spring compressor .I put them in about 5 years ago. They have sagged some since I installed them. Yes I rebuilt the upper and lower control arms and installed the springs and rebuilt the entire suspension. I bought urethane bushings and was going to rebuild the control arms again. After speaking with a few people everyone is recommending different approaches. I have body roll even though I have thick front and rear sway bars with boxed control arms the rear springs are for olds vista station wagon ,I installed them the same time. I still have body roll , I would love to get ride of most of it. I installed KYB Gas adjust shocks they helped some with the 17 inch rims .

 

Just exactly what is the ground clearance at the middle of the engine cross member? Mine is about 6 inches, less to the headers. This is how my car sits as viewed from the side with new 70 GS 455 springs.

I bolted up my uppers (twice now) without anything but putting a jack stand under the lower control arm and letting the upper arm settle into the spindle. I did use tall upper ball joints but 1/2" isn't going to make a huge difference.

 

On your ride height, are you sure that you are fitting the lower part of the spring in the A arm pocket correctly. Simple but sometimes it is overlooked.
