Fall-Line Motorsport BMW G8X F8X M2 M3 M4 Rear Upper Control Arm Bearing Set
Product Description
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.
