Unplugged Performance Adjustable Front Upper Control Arms – Ultimate Edition for Tesla Model S

Designed for precision and adaptability, these control arms allow for precise suspension setup, ensuring your vehicle achieves superior handling and alignment.

Constructed from high quality materials, these control arms are built to withstand rigorous driving conditions while providing reliable performance. Featuring our patented camber pill technology, the flip pill can be used for quick changes between racing and road use camber alignment. This level of precision is essential for maintaining excellent handling characteristics, whether you’re driving at high speeds or navigating tight turns.

These control arms are an ideal upgrade for drivers seeking to optimize their Tesla Model S for spirited driving or to improve the comfort and control of their daily commute. With the Unplugged Performance Adjustable Front Upper Control Arms – Ultimate Edition, you’ll experience a new level of handling and performance in your Tesla Model S.


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 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.


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 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.


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.


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.

Derived through extensive R&D on our track record-holding Model S Plaid race car, these arms are the best-engineered and easiest way to get the maximum front grip out of your Plaid Model S:

  • Fully adjustable front camber, caster, and toe
  • Patented Quick Camber Change Pill design
  • Maximize wheel and tire size and optimize geometry for maximum grip
  • CNC-milled 6061 aluminum for maximum strength while saving weight
  • FEA-simulation optimized to ensure superior static, dynamic, and fatigue strength
  • Sealed spherical bushings for unmatched precision and durability with silent operation
  • Replaces Tesla part numbers FR UPR CTRL ARM, LH, P2 1420321-00-B and FR UPR CTRL ARM, RH, P2

What our customers say
Excellent product from a great team with great customer service! The factory Model 3 Performance's suspension is rather underwhelming, so once you add the Dual Rate Linear Springs along with the Sway Bar kit and Luxury Suspension Kit it completely transforms the car! UP also stands by their...
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 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...
This Ascension-R Racing seat just arrived from Unplugged Performance ( 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!!
Bought the shock and it works great. Definitely recommend for Model Y owners on limited budget.
WIFE APPROVED!!! I have a 2018 Model 3 LR AWD with the stock 18" wheels. I've always felt that the ride was a bit stiff and jittery with the stock suspension. Looking around for a solution, I came across coil-over kits which were expensive and I really didn't think I would need the adjustability...
Perfect companion product for the luxury suspension kit. An absolute must have for those who modify the springs of their vehicle.
This brace was an amazing upgrade for my car. I added the UP rear sway bar first then the full UP suspension then this Strut Tower Brace. I feel this completed the feel i was looking for. The cars back end feels so solid while cornering and over the bumpys feels so solid too. A noticeable...
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. ...
These are absolutely THE BEST brakes ( 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.
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...
Who likes shredded tires? Nobody! Fix the wonky camber on early Model S vehicles with this easy upgrade.
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...
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...
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....
The Willans Safety Harness kit along with the Ascension-R Racing seat just arrived from Unplugged Performance ( 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...
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!
I purchased a set of these Sway bars along with a few other upgrade components for my Model 3 ( 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....
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...
