Tesla Model 3 / Model Y Adjustable Front Upper Control Arms (FUCA)

We strive for perfection with everything we do. We pioneered the world’s first adjustable upper control arms for the Model 3 back in late 2017. Since then we’ve gone through multiple versions, many of which we kept for internal development and never saw public release. Over the years we’ve grown and have had the pleasure of supporting thousands of streetcars as well as setting racing records around the world. Our experience has led us to what we’ve internally called our version 4 front upper control arm. In simple terms, we feel it is the Ultimate. We’ve set records with the fastest Model 3 and Model Y on early prototypes of these and we’re pleased to release them to our clients. Read on to see why we call these the ultimate…

*Updated for summer 2021 onward to enable extreme clearance to ensure no contact with chassis in the most severe use cases. As utilized in Germany on the full TUV road legal UP development Model 3 Performance which is kept at the Nurburgring & tested for over 15,000km of hard Nurburgring track use and counting!

Patent Pending Camber Quick Change Pill

We drive our race cars to the track on Autopilot, set lap records, and drive home. This is the preferred way to experience the amazing duality of a Tesla being the perfect daily and the perfect track weapon. We wanted a solution that was the ultimate in precision for a camber quick change. We came up with a two setting quick-change pill design that can be swapped at the track in 5 minutes using just an Allen wrench and a floor jack. You’ll notice from a top view the clear labeling of Street or Track camber setting of the ball joint. The beauty of this design (aside from the speed of swapping) is that it is precision engineered and machined to allow the most accurately consistent retention of alignment setting that is not achievable as precisely any other way. We all spend a lot of time and money on getting finely tuned alignment settings for our cars. This method keeps the alignment precise between quick camber swaps between street and track. You’ll never need to worry about alignments remaining precisely where you set them, even after much quick camber changes. Simply enjoy two degrees of additional negative camber at the track and when you swap it back you’ll be spot on to your original street alignment.

No Expense Spared – Asymmetrical Billet Design With Camber, Caster, and Toe Adjustment

It isn’t cheap to install parts, get alignment, and race. We figured why cut corners on budget when a few hundred dollars more can make the difference in performance, let’s just build the best product money can buy. Sure enough, these were not cheap to make. Each monoblock aluminum arm encases the ball joint in a massively rigid asymmetrical design. You’ll notice laser etching denoting LH and RH sides reflecting this. Each side has easy to access turnbuckles and bottom access adjustment points for alignment and provides full control of camber, caster, and toe for the ultimate in alignment options. The shape is precisely sculpted in CAD to optimize suspension travel and retains clearance on full compression.

Negative Camber – Sure How Much?

More than you can afford pal. Seriously though, when we tested on our race car we maxed out at 5.8 degrees of negative camber on our race setting (3.8 degrees on street pill setting). It is safe to say that there is more camber adjustment possible than anyone would ever need. On our race cars we find the fastest settings on race slicks require -4.0 degrees of front camber which these do with ease. Want to lift your car and go overlanding? No problem, these can go positive camber as well to offset for increased height. This design allows for the maximum in flexibility of adjustable camber range. Please note that actual max/min camber depends on variables such as vehicle ride height and type of spring/shock combination.

Silent and Low Vibration OEM Type Sealed Spherical Bearing Design

We’ve set multiple racing records with these but you can enjoy them for your daily commute in blissful Autopilot enabled meditative silence as well. We guarantee it, along with all of our suspension products.

Perfect for Air Suspension and Extremely Low Applications

Unlike most replacement FUCAs for Teslas, Unplugged Performance FUCAs feature a unique asymmetrical design to ensure each side is capable of clearing all inner fender and chassis metal work. This means the FUCA can extend further up into the chassis, a required benefit when lowering the Model 3 and Model Y to extreme levels, such as for those with air suspension setups.

Quality You Can See

We spend a lot on materials and we like to show them off in a hi-tech way. We use a rugged and corrosion-resistant Cerakote clear coating to encapsulate and show off the precisely CNC machined and laser etched aircraft grade 6061-T6 billet Aluminum.

Wheel Speed Sensor Mounting

Although not shown in the initial photos, we include in the design an integrated attachment point to securely attach the wheel speed sensor line.

    As part of my purchase of the Luxury Coilover Suspension for my Model Y, I included both the Front Upper Control Arms and Rear Camber Arms, to mitigate any issues with uneven tire wear. When I purchased the UP / BBS Flugplatz wheels with tires, I was relieved that the additional 2 pieces were installed. In my opinion, FUCA and rear camber are required in order to reap the maximum benefit of the upgraded suspension. It creates a smoother ride than stock, with the ability to customize based on your preference.

    I got the FUCAs installed on my 2018 Performance Model 3 and wished I hadn’t waited so long to do it! Now I can do proper alignments with camber on the front, not possible to do with the stock control arms. You can also put custom wheel sizes with super wide tires on the front without worrying about rubbing. I just had it on the track, and the alignment and wider 255/35/20 tires were incredibly helpful. Together with the other mods, I was able to achieve save 4 seconds on my personal best time at Buttonwillow, and the car still has more to give. The car actually rides like a new car now, and in my opinion, better than when brand new. Amazing!

What our customers say
I have a Tesla Model 3 LR but the rep at UP accidentally ordered the MY listing instead which is the same since both M3 and MY share most parts including struts. Purchased as the roads in DC just aren't very pleasant and combined with Tesla's stock struts, it's pretty horrendous. Delivery took...
Who likes shredded tires? Nobody! Fix the wonky camber on early Model S vehicles with this easy upgrade.
Tight on turns and soft on bumps--the mild springs seemed like the best option for folks who want to keep the vehicle as close to stock as possible while simultaneously improving the vehicle ride quality.
I recently purchased the Carbon Fiber long tail decklid spoiler for my Model X, the quality is outstanding, the finish and attention to detail of the spoiler is amazing. Looking forward to installing it on my X when it's being wrapped.
Excellent product from a great team with great customer service! The factory Model 3 Performance's suspension is rather underwhelming, so once you add this Sway Bar kit along with the Dual Rate Linear Springs and Luxury Suspension Kit it completely transforms the car! UP also stands by their...
The pictures on the website does not do justice. the wheels look extremely beautiful. Kirk was extremely helpful, and coordination was amazing. My wheels are gloss black, not able to add a picture to the review if not would do it. I went with slightly bigger wheels 20x10.5 front and 20X11 back. ...
This is by far the best front fascia out there and its makes the Model 3 look so much better! It gives it a much sportier look and I get comments on it all the time. One of the simplest upgrades that makes a huge difference as far as the look of the car goes. Couldn't be happier with how it looks....
This Ascension-R Racing seat just arrived from Unplugged Performance (https://www.instagram.com/p/Cv8f-5cvDuE/) It looks absolutely well manufactured, high quality and lightweight making it a must have accessory on any Tesla going to the track! Looks stunning and well designed!!
The Air suspension upgrade kit works well on my refreshed Raven Model X with the upgraded Air Suspension kit. The suspension setting on Low not only improves the look but also benefits from higher efficiency with the advantage of location based auto raise function....
The Willans Safety Harness kit along with the Ascension-R Racing seat just arrived from Unplugged Performance (https://www.instagram.com/p/Cv8f-5cvDuE/) The 6-point Harness kit goes hand in hand with the design of the racing seat. It looks absolutely well made and high quality making it a must have...
These springs were the first real mod I’d ever done to my Tesla and I’m so happy with the way they turned out. They really complete the look on my model 3. And I was surprised to find you don’t sacrifice anything in terms of ride comfort by adding them. The only problem is that now that I’ve...
Perfect companion product for the luxury suspension kit. An absolute must have for those who modify the springs of their vehicle.
These wheels are insanely light and strong! And, they look the bomb! If I didn’t look while picking them up, I would have thought they are carbon fiber! The same spec as was originally used on the Bionic Phoenix Model 3 race car! I put in my fastest time at Buttonwillow on these wheels...
These are absolutely THE BEST brakes (https://www.instagram.com/p/CveWNmjvKwT/) They work flawlessly lap after lap with it's nonstop stopping power, they will last forever. Incredible value for money and Highly recommend to anyone considering using their Tesla for both track and street.
Significantly improved feel from this suspension kit. Don't forget yo get camber adjustments and springs that make this suspension upgrade feel like a whole new car!
Bought the shock and it works great. Definitely recommend for Model Y owners on limited budget.

I had my Coilovers installed by NV Auto in Hamilton Canada. They did a good job and I now have a great ride. After about a month of driving I went one step further and put new 18” rims and tires on. This really improved the ride and is is a joy to drive my Tesla again. Thanks unplugged...
I purchased a set of these Sway bars along with a few other upgrade components for my Model 3 (https://www.instagram.com/p/Cv8c-F2PEYP) The sway bars improve the ride quality, reduced body roll making the car more rigid and stable. Installation and setup was easy, being adjustable is an added bonus....
