01 Step 1: Lift the Vehicle

Place the truck in the highest setting and place the truck into jack mode. This is a safety measure to make sure that the ride height does not change while servicing the vehicle, while also providing additional clearance to some necessary access points.

02 Step 2: Remove Rear Diffuser

Using a 10mm Socket, loosen the following 7 bolts that secure the rear mid panel to the vehicle. Keep these bolts as they will be used later during reassembly.

Next, using a 15mm socket, loosen the following 3 bolts to allow the rear mid panel to be removed from the vehicle. No need to fully remove these 3 bolts.

INVINCIBLE CYBERTRUCK REAR SWAY BAR INSTALLATION0003
Using a 10mm socket, remove the following 6 bolts securing the underside of the rear diffuser to the vehicle. Keep these bolts as they will be used later during reassembly.

 

Using a T30 torx bit, remove 3 bolts securing each side factory rear diffuser to the factory rear bumper cover. Keep these bolts as they will be used later during reassembly.

 

Using a clip removal tool, remove 4 push clips securing each factory rear fender liner to the factory rear diffuser as shown below.

 

Using a flat head screwdriver, rotate all 3 factory tow hitch cover retainer clips counterclockwise by 90 degrees as shown below.

 

Pull the tow hitch cover away from the vehicle in a swift like motion. Be sure to disengage all retainer tabs.

With the tow hitch now removed, proceed to the underside of the bumper to access where the hardware securing the diffuser to the rear bumper is located as shown below. Using a T30, remove both bolts securing the back side of the factory diffuser to the factory rear bumper cover. Keep these bolts as they will be used later during reassembly.

 

Using a clip removal tool, disconnect the following wiring harness from the factory rear diffuser as shown below.

 

Next, disconnect the rear speaker wiring harness to ensure the diffuser can be removed without damaging any cables.

INVINCIBLE CYBERTRUCK REAR SWAY BAR INSTALLATION0018
Now that most accessible power cables have been disconnected, proceed to disconnect the rear diffuser from the rear bumper. It may be helpful to have a second set of hands on the back side of the bumper to help disengage the retainer tabs securing the rear diffuser to the rear bumper. Be sure to support the diffuser after the clips are disengaged as there is 1 more cable assembly that needs to be disconnected before the diffuser can be pulled away from the vehicle.

 

Using a clip removal tool, disconnect the following wiring harness from the rear diffuser so that it may fall away from the rear bumper without damaging any accessories.

03 Step 3: Remove Factory Rear Sway Bar and Endlinks

Using a 15mm socket, remove each nut securing the factory endlinks to the factory lower control arms. Keep these nuts as they will be used later during reassembly.

 

Using a pry tool, remove the rear wiring harness tab from the factory sway bar bracket and diffuser bracket.

Now that the sway bar is disconnected from the vehicle, carefully guide the sway bar away from the vehicle.

 

Using a 15mm socket, remove each nut securing the factory endlinks to the factory rear sway bar. Keep these nuts as they will be used later during reassembly.

04 Step 4: Assemble Rear Sway Bar

First, set the factory rear sway bar near the UP rear sway bar to ensure that the orientation is matched.

INVINCIBLE CYBERTRUCK REAR SWAY BAR INSTALLATION0047
Using the provided grease packet, apply grease evenly to each provided sway bar bushing as shown below.

INVINCIBLE CYBERTRUCK REAR SWAY BAR INSTALLATION0049
Next, carefully guide each sway bar bushing over each end of the UP rear sway bar as shown below. Be careful to not apply grease to the ends of the bar if possible as you want all grease to be applied in the intended usable location.

INVINCIBLE CYBERTRUCK REAR SWAY BAR INSTALLATION0050
Apply any excess grease left over either on the sway bar or in the grease packet onto the outside of the sway bar bushings.

INVINCIBLE CYBERTRUCK REAR SWAY BAR INSTALLATION0051

05 Step 5: Install UP Rear Sway Bar

Next, identify each sway bar setting as shown below.

INVINCIBLE CYBERTRUCK REAR SWAY BAR INSTALLATION0048
Using a 15mm socket, secure each endlink to the UP sway bar in the preferred setting using factory hardware.

INVINCIBLE CYBERTRUCK REAR SWAY BAR INSTALLATION0052
Once both endlinks have been installed on the UP rear sway bar, proceed to install the UP rear sway bar on the vehicle in the same orientation as the factory sway bar. Using a 15mm socket, loosely fasten 2 factory bolts and 2 provided washers to secure each UP rear sway bar bracket and backing plate to the vehicle.

 

With the sway bar loosely secured to the vehicle, proceed to loosely fasten both factory rear endlinks to the rear lower control arms using a 15mm socket.

 

Now that the sway bar and endlinks are loosely installed on the vehicle, it is time to apply final torque. Using a 15mm socket and a torque wrench, torque the UP rear sway bracket bolts to 36.9 ft/lbs while pushing the bar upward to maximize bar clearance during dynamic suspension movement.

 

Next, using a 15mm socket and torque wrench, torque to both endlinks to 33.2 ft/lbs.

 

Congratulations! Your UP INVINCIBLE rear sway bar has been successfully installed!

Once all hardware is loosely mounted, using a T30 torx bit and a torque wrench, torque to 4.4 ft/lbs.
Next, secure all wiring harnesses to the factory diffuser as shown below.

Extremely well built and engineered. Best on the market.
Cordell November 24, 2025
The "Road Warrior" Curb Guards work as advertised for the most part. I did not find them to be as "protective" as advertised in all the Youtube and promotional videos. Just a day after I installed my Road Warrior wheels, I hit a curb while turning at a slight angle. This damaged the curb guard as...

Love the simple look to this decal
edgar M. November 21, 2025
Pretty awful. Package’s held for weeks for incorrect shipping details 700 dollars in import tax and broken products arriving …… very disappointed. Oh and never a timely response or method to contact other than email…..
Brad November 21, 2025
Had UP install the HD front bumper with the 11" LEDs. Robust steel construction, makes the truck look more aggressive but lines remain clean. This bumper is what Tesla should have equipped the truck with out of the factory! LEDs are super bright as well. Simply the best looking, best designed,...
Megatron November 19, 2025
Had UP install the HD rear bumper with hardcore trailer hitch receiver including flood lights. Utility is awesome, the arms are robustly built and carry my full-size spare, a 20" beadlock wheel with Wildpeak AT4Ws with ease. No rattling whatsoever, the tire is locked in. Swing arms themselves can...

Went with the burnt titanium, simply looks gorgeous with the finish!

Robust carbon steel construction. Lines look very clean with the HD front and rear bumper installed. Have not seen a cleaner looking aftermarket rock slider for the CT, love mine!
Megatron November 19, 2025
I had another set carbon steel running boards on my Cybertruck for a while and finally got to see the UP Invincible HD Rock Sliders while out at XTakeover this summer. They looked so good and were noticeably more sturdy than what I had on the truck. I replaced mine with a set of these HD Rock...

While the overall weight reduction isn't much in totality, it is noticeably lighter compared to the original lug nuts.
Josh H. November 17, 2025
I had an issue of the camber being no longer able to be adjusted to specs. The friends of UP took care of me. Easy to swap as well. Went to a shop yo align it and car is up to specs again and straight as an arrow. Love it! Thank you UP!
Kamil K. November 16, 2025
Overall, I'm very happy with the UP Forged Road Warrior 19" Wheels that I got for my new Model Y Juniper. They look great and seem very sturdy. The service and communication from Unplugged was great especially with my salesman, Shahar. It took about 3 months for me to get my wheels but it was worth...

Really nice jacket. A must have for a UP enthusiast!
Montage Ø. November 12, 2025
Unplugged Performance installed front/rear sway bars on my Model 3 Performance Highland. The change was instant: less body roll, flatter cornering, better grip, and precise control. It sharped handling without hurting ride comfort. This is a great value and would highly recommended.
Alex H. November 12, 2025
I received the lower compliance Aft arms today (fri), after ordering on mon. I wasn't sure I'd have time to install, since I already had a lot on my plate, but this afternoon I had a couple spare hours, it ended up only taking about 45 min, including getting the Tesla on jack stands. my...
Rob T. November 09, 2025
