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.

Wow Great Deal!
Color: Black
I have been using this chair for a month now and I am honestly impressed for the price I paid. I work from home so am using this chair 24/7. I had no issues with assembling it myself as a 35 year old female. Instructions were simple to follow and took me maybe 30 minutes to put together. Its sturdy and comfortable. I appreciate the padded arms and the seat bottom is also a nice thick cushion. Added bonus for the head rest and that it is adjustable. Definitely recommend.

Very comfortable office chair

This ergonomic office chair is very comfortable and has good lumbar support and a nice headrest. It includes all the necessary tools and takes about 20 minutes to fully assemble.

Overall, this ergonomic office chair provides relaxing comfort during long hours sitting with support for your bottom, back, head and arms. It's a good value for the price.

Good quality and arrived quickly
Color: Black
I was very pleased with how easy this chair was to set up. Affordable, arrived quickly. The only reason it isn’t 5/5 is because on of the arms had a small dent, possibly due to not enough bubble wrap during shipping. Other than that, the quality is great.

Awesome chair so far
Color: Black
My old chair can go in the trash immediately because it set the bar so low (picked up from a giveaway - squeaked anytime it's leaned on, always sinking upon sitting on it). This Ergonomic chair blew it out of the water. Happy with this purchase. This chair took me an hour to assemble, which I expected. It feels extremely sturdy and comfortable. Lumbar support feels great! I love the various adjustability options this chair offers. Hope it lasts for many years. By the way, I am 175 lbs, 5'10".
