Eliminate Rear Suspension Flex with Fall Line Rear Upper Control Arm Bearings – BMW G80/G82/G87 M2, M3, M4

Upgrade the final weak point in your M-car’s rear suspension with Fall Line’s Rear Upper Control Arm Bearings. Precision CNC-machined and made in the USA, these replace the factory rubber bushings with full stainless spherical bearings for a tighter, more planted rear end under load.


Why Upgrade?

Say Goodbye to Unwanted Geometry Change

The OEM bushings in the rear upper arms flex under cornering loads, causing undesirable camber and toe changes – particularly in hard driving or track use. Fall Line’s bearings eliminate this compliance, locking the rear arms into a more consistent geometry to maximise grip and predictability.

Precision-Built for Performance and Longevity

  • DMG Mori 5-Axis CNC machined components

  • Full stainless steel bearing assemblies (hats, bearing, housing, spiral locks)

  • Designed to replace the inner bushings on the rear upper control arms

  • Maintains proper alignment throughout suspension travel

  • Dramatically improves rear-end stability and feedback

Motorsport-Level Feedback – With Real-World Considerations

With any spherical bearing upgrade, expect an increase in NVH (noise, vibration, harshness). These are performance parts for owners who prioritise response and feel over absolute comfort – ideal for road-legal track builds and spirited driving.

Works great for scent work! Bounce is great for air retrieve!
Size: 2-pack, Style: Duo, Size: 2-pack, Style: Duo
My dog doesn’t know he loves them yet but I do! They are a little softer so when we do air retrieve, I don’t have to worry as much about his teeth! I’m hoping he will learn to find them by smell vs sight. We often play in the evenings and he tends to loose his ball. Love chuck it! Right now, we have about 10 chuck it balls! The tennis balls don’t work for air retrieve! Chuckit does!!! Love the thrower too! Saves my arm!!!!

I guess the smell is offputting
Size: 2-pack, Style: Duo
My dog loves chocolate stuff. But for some reason, wasn’t a huge fan of these balls. She played with them a little bit, but they’re not her favorite.

Chef’s Kiss! Quality Product at an Amazing Price!
Size: Large
The large is a perfect size for my 66# and 110#. If you have a smaller dog, consider a medium. Fill them with peanut butter, 1/2 banana each, wet kibble (paste) or pumpkin puree, and put into the freezer. Not as stiff as their Kongs. Both dogs are strong chewers and these have held up. Clean the inside with a baby bottle brush.

Stands up to puppy teeth!
Size: Medium, Size: Medium
I was fostering 2 7-week old puppies that chewed on EVERYTHING! I got these AND a couple of the Kong brand chew toys. These have stood up much better to the puppy teeth than the Kongs did. I throw them in the dishwasher (not every time) and I also have a small straw brush to clean them. They are easy to fill, and once they are done with the treats (PB butter, yogurt, pumpkin, apple sauce etc.), they continue to chew on these. When you throw them, they have a fun bonce. I ended up foster failing one of the puppies, but we still use these often. They still look brand new and I have had them for about 6 months. I got the medium, my dog is about 13 lbs now and the size is perfect for her. The material is strong and I don't hear a peep when she is chewing on it. I would 100% recommend these!

Great toys. Bouncy, chewable long term.
Size: Medium, Size: Medium
We got these for our puppy and to see how they would compare to kongs. Our dogs love these more than the kongs and so far, with two chewy dogs, they have not destroyed these yet. They are very bouncy and provide a lot of chasing fun. We will be buying more and we recommend these.
