Specialty Products Company 4RUNNER & FJ UCA (PAIR) 25480

I really love these. Very adjustable. The extra camber adjustment gave me the additional clearance that I needed to run an almost 13" wide tire on my 4Runner (with aftermarket wheels of course). The additional caster adjustments are a great feature as well, and allow you to add additional caster that is lost when lifting your vehicle.Very high quality product and I got the best price and lightening fast shipping from Amazon. Most 4Runner owners that buy aftermarket UCA's end up with SPC (Light Racing) ones because they are easily the best value for the money.Install was very simple.One word of advice: pictured are the old style bushings. The new ones require greasing and come with a pack of grease. Be sure to grease the bushings before installing them or you will have squeaky bushings... Ask me how I know.Oh well, still love the product. Yes, I'd buy these again, and yes I'd recommend them to anybody looking for aftermarket upper control arms.

These control arms give you more +caster in the front alignment and compensate for lifted trucks. I installed in my mildly lifted 4Runner and got an additional 2 degrees of caster which greatly improved handling and straight line stability. They’re kind of expensive but very well made. I have SPC arms on another car and have only good things to say about their products. Installation only took 2-1/2 hours and my truck is much more fun to drive after this upgrade.

Fits my 2011 4Runner perfectly. These came with the new style bushing and I have not had any type of squeaking in over 8000 miles now. I highly recommend these to anyone who has lifted their Toyota 4WD - these will get your alignment back in spec. Very heavy duty, big ball joints. Installation can be done with simply hand tools and should take an hour or less.

I installed these SPC upper control arms on my 2010 FJ Cruiser the other day. I was impressed by the design and engineering of the adjustable caster system, the ball joints, and the bushings, all of which are very robust yet highly functional. Install directions are clear and well written, though they do justifiably assume the installer has some degree of experience and knowledge of suspension systems, but as an experienced amateur I had no problems.

So many features to like. Real ball joint that is greasable and replaceable. Huge range and many settings for caster settings. Good range for camber. Rubber isolated maintenance free upper arm bushings. The most articulation and best tire clearance of all replacement arms. All at a very reasonable cost. When they switch to a full forge arm over the older welded tube I was sold, glad I made the purchase.With these arms because there is such a huge sweep in caster angle you can move your wheels pretty far forward so you don't have the famous tire to frame/body mount interference. No need for body mount chopping if your tires and offsets are reasonable!

I installed these in my 08 GX470 and install was straight forward.Went out for a test drive around the block and lifted the vehicle to make sure everything looked good and found the driver side ball joint boot torn in the middle.I reached out the company and absolutely no word from them and Amazon said nothing can be done other than return them. I simply wanted them to send me a new ball joint so that I have to take all apart again and reinstall again…. Maybe this review will help.Send me a new one!! This is unacceptable.

Regularly maintained. Both the bushings and the ball joints on both UCAs are loose/loud and done for within 15k. SPC wants them sent in to see if they fall under warranty.Needless to say that's extraordinarily inconvenient.I'll probably just buy another brand instead of replacing the parts and rolling the dice again.

No issues so far
