Back when we took our Cybertruck for a torture-test jumping run at the farm - yes, that video from last year - we finally managed to break something after enough jumps with a 7000 lb truck. Eventually, a factory stamped steel front upper control arm bent. Frankly, it was a matter of time. In finding the limits of the Cybertruck, we set our sights on addressing the first thing that we were able to destroy. Months later, we have this.

The billet MPP "Flight Grade" Cybertruck FUCA is complete with adjustable height provisions, sealed spherical bearings, and the same infinitely repeatable camber adjustment system as our popular FUCAs for the Model 3/Y. While it would have been easy to put some open spherical bearings on the inboard end, we opted to keep sealed bearings and ball joints throughout to ensure that these arms would endure the test of time, and not leave your truck squeaking and creaking over every bump a few years down the road. These sealed spherical bearings and ball joints come from high-end European cars, and these joints are designed to last for tens if not hundreds of thousands of miles without degradation.

While there will surely be some cheaper (and sometimes more expensive!) options available in the future, we are confident none will be as easy to adjust as ours or be as quiet and smooth on the street.

This product exists and is installed on our shop Cybertruck. We're now ready for pre-orders for our first production run! This isn't just a rendering with an unknown availability date!

Does that mean the casting bosses are now the weak point? Or was the failure due to a range of motion/ binding issue on the original?

The arms look beefy enough but it appears that the two small bolts holding the ball joint to the A-arm would be subject to immense stress over time.

I wonder if installing a set will void your factory warranty if front suspension issues arise.

Very nice! I assume this is AWD and not the Beast?
This is an AWD yes, if you'd like, please post photos so that we can see if the Beast is different - I believe they are the same!

There are also dowels between the balljoint, shims and inner arm that carry all of the shear load - the bolts only provide the clamping.

In all of our other Tesla components, Tesla has never voided a customer's warranty due to use of our components. It is highly unlikely that they could prove that our parts caused an issue if the vehicle is operating in the original ride height range.

Lifting or lowering the truck excessively would be a different story!

Be a little careful there. Just because it hasn't been voided. One must be prepared for a fight with the SC. Also be weary of people that say "never". Seems here we see other parts people had to pay for because of changes. I suggest people look up MPP additions and warranty coverage in google and see what they get.

Also I remember the party box issues. May not be suspension. Yet you said all of our Tesla components.

That is why you keep the stock components to swap back in case of an issue before bringing in for service. ?‍♂

Yeah that is what people want to do. Swap control arms in the garage to go into a service appointment. LOL. Did you read that after you typed it?

What if one never solves the problem? 6 pages to a squeak. Tell me installing this stuff is worth it? Or do people just like the blue anodizing? I bet squeaks and rattles trump the blue aspect of cool factor. https://teslamotorsclub.com/tmc/thr...-making-ping-sound-when-turning-wheel.185347/

The popularity of these aftermarket CT UCA’s remains to be seen. Aftermarket companies sell a ton of UCA’s for the Toyota Tacoma. Owners love to mod their Tacoma’s.

There are also dowels between the balljoint, shims and inner arm that carry all of the shear load - the bolts only provide the clamping.
There is no significant shear load on the shim area, the A-arm is freely pivoting so any shear force simply causes the ball joint to rise or fall on the pivots. The resistance of the air springs and dampers don't act through this ball joint/shim area either. The only load on the A-arm comes from the wheel trying to change camber in/out (which the A-arm resists). That force is in line with the clamping bolts.

I'm still waiting for a photo of the damaged OEM A-arm (because that must have been an incredible force to collapse the A-arm when the force was in-line with the A-arm).

There is also fore/aft shear due to wheel longitudinal loads and braking torque. The knuckle design does provide the upper arm mechanical advantage.
