 Description

The Dirt King Billet Upper Control Arms are precision-machined from 6061 aluminum, offering exceptional strength and a refined appearance. Designed to optimize suspension geometry, these arms allow for increased front lift and suspension travel when paired with Dirt King shocks. Factory control arms often compromise geometry and structural integrity due to excessive articulation at stock joints, but Dirt King arms solve this with improved caster settings and re-engineered pivot angles for better handling and articulation.

A key feature of the billet arms is the adjustable inner pivot system. The maintenance-free Probearing SilentSpin bushings provide superior ride comfort, with a polyurethane outer layer that dampens road noise and a self-lubricating composite core for smooth, quiet operation. The bushings are optimal for on-road and off-road performance, delivering excellent handling with no compromises.

Billet UCAs are equipped with heavy-duty Probearing ball joints for long-lasting durability in harsh environments. These billet upper control arms are built for lasting performance and easy installation, making them an excellent upgrade for any vehicle.

Absolutely great for travel but not enough wattage to charge a macbook without the macbook brick.
So this thing is absolutely amazing for travel. The extension cord is a great length. The usb ports are secure and snug and it really works very well, it's by FAR my favorite adapter to travel with. I do have one nitpick - the photos clearly show it charging a macbook and yes, it can but not with a straight cable you still need to plug in the macbook power brick to it. I was hoping to avoid that but this adapter does not have enough wattage to charge a macbook without the brick. I included two photos showing the difference in wattage between this and an macbook power brick.

Great for use in Italy!
We spent 3 weeks in Italy in May of 2023. This was so easy to use for making sure all of our cell phones and power bricks were fully charged for the next day of discovery while in Italy. Plugged in effortlessly everywhere we stayed in Italy. We used all the charging ports and the USA outlets for two dual voltage power packs (remember the Italian grid is 240VAC not 120VAC like in USA) and my dual voltage CPAP power brick. No problems any where - it worked flawlessly. I would not suggest using it for curling irons or blow dryers or any very high wattage devices and anything you plug into it that does not say dual voltage on the device may be destroyed and possible catch fire! So do be aware of what you use with it as it does not drop the voltage to 120VAC from the 240VAC Italian wall outlets. Nice feature is that it comes with an adapter you can use when you get back to USA so you can use it at home till you pack your bags for the next trip!

Worked as expected, lots of USB ports.
Just used on my trip to Paris, worked well and I liked having so many USB ports. The long cord was great because my hotel was rather vintage and the outlets weren't in convenient places. Glad to see it will also work for my next trip. I appreciated that it came with adapters for the US also so I could test it at home before I left.

Perfect for travel!
These "extension cord" power adapters were perfect for us during a recent trip to Europe! They come with multiple adapters so that you can use the adapter in several countries. Best of all, one of the adapters is for North America, so we can still use them at home! Each adapter has three 3-prong plug sockets (meaning you can use either 2-prong or 3-prong plugs), one of which is set slightly apart from the other two to accommodate a larger plug. Each has four USB ports, plus one USB-C port. Plus, it has a 5-foot extension cord, so you can reach that one socket that never seems to be where you actually need it to be! That made it perfect to be able to set the adapter on the bedside table and charge all of our devices at once, but still keep our phones close at hand for checking time, setting alarms, etc. With all of that in one little box, we were able to eliminate the bag-full of various adapters we've had to pack for past trips. Definitely recommend these for your travel needs!

Prefect for our trip.
Color: Muted Pink+Lilac, Size: Large
I bought this travel holder because of the strap that I can fit around my neck. The rings and clasps are metal. There are two rings on the back side to hook the strap to which I really like because less tension on the neck. There was plenty of room to fit our passports with protective covers into the slots on the right. I adjusted the strap long enough that it still lets me easily un-zip the holder while keeping it securely around my neck. No worries about accidentally leaving it somewhere. Only time can tell how much it will hold up to ware and tare. Feels and seems it will hold up.
