PERFECT FIT, EASY SWAP, HOW-TO VIDEO MADE IT A SNAP
Chaned out all 4 control arms in one day. Never done front suspension before, but with the how-to video it was a piece of cake. My truck is a 2000 Silverado 4x4 with 227K miles on it with all original parts. It rides and steers like it's brand new again.

01 Suburban control arms with bushings, and ball joints
Watched several videos on how to change these parts, and the one by A1 was best - particularly how to unload the torsion bars. Video was the final factor/reason I ordered from A1. However, really good price on these parts, too, and they bolted right in. Made the front suspension feel tight and new again. This is my second purchase from A1, and I've been very happy both times. Parts were shipped and arrived quickly. Having the ball joints and bushings already installed made this job way easier and quicker than it otherwise would have been. Thanks to A1 for those videos - that's how I knew about you, and they're very helpful!

Great alternate
Control arms are a lot easier to replace than the ball joints and cost the same from 1aauto. The lower are more difficult but still possible for the weekend mechanic like me. Instructional videos were great and showed everything I needed to do.

I ordered control arms front struts for my 2009 Ford Escape and ordered upper and lower control arms and a bunch of other parts for my 2004 GMC savanna van. All the parts came when they said and with the how to videos all the parts were install with no problem! Thank you again for great parts and service !

Who is the manufacturer of these control arms?
Rob B on Apr 12, 2017
BEST ANSWER: I would seriously consider paying a bit more for another loaded control arm of better quality. I installed this kit in a lifted Silverado and I'm pretty sure I will be doing the job again next year or sooner. It could be that lifted vehicles eat suspension parts though. Most likely manufactured in China
are the upper control arms in this set good for a lifted silverado? lift height is 6 inches.
hunter l on Jan 4, 2018
BEST ANSWER: These upper control arms work with a Procomp 6 inch lift other companies I do not know they may use their own style control arms. Depends on what 6 inch lift system you have
