ND Miata Rear Upper Arms (RUA) greatly increase the range of rear camber adjustment for high performance track/street applications and are a must for lowered cars to meet alignment requirements. The adjustment range provided by the eccentric washer on the OEM control arm is insufficient to get camber back into proper spec. 

Our Rear Upper Links feature gun drilled 2024 Aluminum center links, clamps, and clevises, along with Blue Anodized Titanium socket head cap screws and our 360 degree rotating clamp system. This combination provides superior strength, performance, durability, and ease of adjustment. Long gone are the days of fumbling with wrenches to tighten jam nuts while trying to trying to keep your bearings oriented correctly. A simple 3/16" allen key is all that is required to lock down your alignment settings!

FK Spherical Rod Ends eliminate the soft worn out bushings on the stock links to reduce alignment change in the rear suspension under hard cornering, acceleration and braking. They feature a Teflon liner to provide quiet operation, low friction, smooth articulation, and eliminates bushing deflection under load. The PTFE liner is chemically bonded to the inner diameter of the race. The liner offers a very high load carrying capacity and has greatly increased dynamic wear characteristics. The operating temperatures of the liner ranges from -65º to 325ºF, offering robust reliability for both street and track use.

Sold as a pair.

Made in the USA.

Really Nice Shelves BUT....
Color: Rustic Brown, Size: 36"L x 8"D, Set of 2, Color: Rustic Brown, Size: 36"L x 8"D, Set of 2
I do like these shelves, they look great for cheaper low end particle board made to look like wood. However I took off stars because they made installation unnecessarily hard. I'll explain.... If you look in my picture the mounting bracket has plenty of options/slots to use. AND in the instructions they clearly show you how to find studs to properly mount the brackets. Meaning the manufacturer know stud distance. They even show in the instructions that studs are clesrly 16" apart! Now get this, the mounting brackets are plenty long enough (roughly 22" without measuring) to mount on two studs 16" apart so the shelves are mounted in wood which is stronger and superior mounting instead of drywall. HOWEVER, THE SLOTTED HOLES ON THE MOUNTING BRACKET ARE NOT 16" APART. None of them. There's tons of slotted holes to use on the bracket and zero of them are 16" apart. Now if I want to mount screws jn 2 studs I have to drill in the mounting bracket to make a new hole. Taking up extra time, messing with the integrity of the mounting steel. I don't understand. It's almost like they did this on purpose. What should have been a 10-15 minute install turned into getting proper drill bits, drilling metal, and taking 45-50 minutes to do it properly. It just put a sour taste in my mouth and that is my reasoning for the 3 of 5 starts. I would make it 3.5 stars if it was an option. Otherwise the shelves look pretty decent for low end shelving. I recommend them only if you're handy with a drill and tape measure. If you can handle drilling the mount bracket to go into a stud, go ahead and grab these.

Lengthy Shelves
Color: Black, Size: 72"L x 8"D, Set of 2, Color: Black, Size: 72"L x 8"D, Set of 2
I love these shelves! I specifically wanted shelves that were very long and that would, when put together, span the length of my room. These fit the bill! Quality: I was very worried about finding something that would hold up a good amount of weight, knowing I wanted to books on these shelves above my head! And I also wanted something with a nice texture that would be easily whipped down for dust. Both these points were covered. I have hade these shelves for several months now and they have successfully held ip a decent bit of weight, is a true black cooler with wood grain detail, and has not faded in color with dusted and whipped down to be cleaned. These are great quality and with the price!

Great shelf for price!
Color: Natural Oak, Number Of Shelves: 1, Size: 35.4 inches, Color: Natural Oak, Number Of Shelves: 1, Size: 35.4 inches
Great shelf for price. VERY easy to install. We put one side of screws of metal bracket in studs to make it sturdy & stable. This was KEY! Follow simple drawing dictions and you can’t go wrong! Was Leary about some bad reviews but we had no issues. Came quickly with no flaws. Looks great and is very light, but is stable when put into bracket correctly. Size is beautiful with the thickness & depth of upscale shelf. If you want a nice shelf that doesn’t break the bank- get it. This one worked well for us!
