Happy with purchase.
Order shipped very quickly, and I received everything I ordered. Quality seems pretty good for not being name brand. Only issue with the whole job was getting the old OEM stuff off. Would buy again.

Everything you hope it will be
I am an idiot...

But with, I mustered the courage to attempt the unthinkable; perform DIY maintenance on my truck.
Shipping: My parts were ordered on Tuesday at 2:58pm, shipping from Kansas to Alabama, and arrived to me on Friday at regular UPS delivery route timing. Though the box came looking like it had survived an old stage coach ambush by outlaws in the old West, the parts were protected and showed no observable damage. The parts came in individual packages with a sticker on each identifying a part number. Also included was an invoice with the part number and part name for ease of correlation between packaging and parts. This was important to me as I'd never held a tie-rod in my hands before and had no idea whether they were destined for left or right side (or if it even mattered).

Compare to OE: Everything I removed from my truck looked identical to the parts from 1AAuto, with the exception of a few minor differences. The OE nuts were "taller" and had more threads compared to those from 1A, but the thread patterns were the same. The upper control arm ball joint, as the product description reads, contains a sealed ball joint pre-pressed in. While the joint is pressed in, the ball joint was not sealed and required installation of a zerk fitting and to be greased. No big deal, but I wasn't expecting that. Also, the upper control arm from 1AAuto came with tapped holes for screwing in the brake line bracket and ABS sensor line bracket. My OE part just had a small, square hole for the ABS line bracket and I had no screw for this. No worries there as I was able to solidly secure the line with a zip-tye and will eventually get a screw for it.

Other than these minor differences, I found nothing askew with my new parts.

Installation: While 1AAuto doesn't have a video for pressing in ball joints they do have a video showing installation of everything else. It took me about 14hrs. to complete the installation and put 4 wheels back on pavement but that's because I'm an idiot (and attention to detail never killed anyone). If you can get the old parts off, you've done the hard part and already know how to put this kit back on, as it is simply the reverse of your previous actions.

I will be buying all my parts from these guys from now on. Have no fear with this kit if you're looking to tighten up that front end. It's everything you hope it will be.

Parts fit great
My initial satisfaction with these parts is great. I didn't change them myself but the mechanic who did told me they worked great. The price was very reasonable and they shipped and arrived quickly. I have bought parts from 1A before and will continue doing so in the future.

Good fit, seems to last!
Installed two of these now. No issues on the first in 2 years. Second went right on and has done well so far. Hardest part is getting old parts off.

How do u install lower ball joints ?
Mark da shark on Feb 10, 2017
BEST ANSWER: The lower ball joints must be pressed into the lower control arm with use of a ball joint press. You may rent a kit at any local auto part store, and upon removal of the c-clip the process should be fairly easy to perform.

The upper ball joint started spinning with the stud, whiled tighting the castle nut. What's the problem? Is it the upper ball joint ? Factory promble?

Will this fit an 05 silverado 4wd with a 6 inch lift?
