I do recommend
They look awesome, work great, it lacks instructions which can be concerning when doing install. my recommendation to anyone buying these, don’t do what I did which is at the point of install I came out 1.25” on the adjustable joints. When I was done the alignment was TERRIBLY off and when I went to get the alignment done the bottom could only be adjusted so much it couldn’t account for the 1.25” I did on these control arms. I had to take them off and go back in 1” so that the alignment could be re-done correctly. Once I went back in it was perfect 🤩 and I love the smooth ride Again, instructions on this would have been great. Moral of the review, install them as they come for the best outcome don’t mess with the adjustments unless really necessary which you can always come back and do but for the initial install I recommend you put them in the original position they come in. Hope this helps.

I like it. looks good too..
2014 FJ nice well made piece. You will have to make an extender for the wheel speed sensor wire as the mounting hole is drilled in the wrong piece. Make sure when the suspension is cycled the sensor cable does not strangle its self. Easy to align. Just wondering where I would get replacement ball joints if needed.

Returned my first order for missing bolts
This is my second after returning the first set. This one has a large gash in the aluminum. Be cautious of what you buy and always check for missing parts.

My truck handles different, but I love these UCA's
I like them but if you're going from stock UCA's to these, know that the stiff ride you had before will be gone. These things are made for rocks and logs and ruts and off-road stuff, not the street. The ride is good, but it's "softer" now and that was unexpected. Still though, I love these and I have adjusted to the difference in handling characteristics.

Solid Budget-Friendly Adjustable UCAs (2006 4Runner 4WD)
So far, these upper control arms have been working great on my 2006 4Runner 4WD. Installation was straightforward—completely plug-and-play with no modifications needed, which was a big plus. My only complaint is that they don’t come with any real instructions, especially when it comes to dialing in the adjustments. If you’re new to adjustable UCAs, you’ll probably have to do a bit of research or trial and error to get them set up properly. That said, for the price, these are a solid option. They feel strong and have held up well so far, handling everything from whoops to crawling without any issues. They also provide a good angle for my 2.5-inch lift, and I haven’t experienced any binding. If you’re in the market for adjustable UCAs but don’t want to spend the high cost of big-name brands, these are definitely worth considering. Great value for the money. I’m giving g this a 4 star just because it didn’t come with instructions or reference for the adjustability. I did have to go through some trial and error with adjustment and ultimately ended up going to an off-road shop to get it properly dialed.

elle m’a duré moins de 7 moins
Très belle pièce, mais de mauvaise qualité. Même en en prenant soin et en l’utilisant seulement sur route, elle m’a duré moins de 7 mois. La rotule du pivot est endommagée : elle fait du bruit et a du jeu. J’ai essayé de trouver la pièce de rechange, mais il semble qu’il faut remplacer tout le bras de contrôle, car il n’y a pas de pièces pour la réparer. NE GASPILLEZ PAS VOTRE ARGENT. Note : l’autocollant est décoratif, puisque le kit de suspension est de cette marque (EIBACH).
