Product Description

Fall Line Motorsport Rear Upper Control Arm Bearings are a precision suspension upgrade for BMW M2, M3 and M4 models, designed to reduce unwanted flex in the rear upper control arms. By replacing the factory rubber inner bushings with full stainless spherical bearing assemblies, they help create a more stable, responsive and predictable rear axle under load.

The original BMW rubber bushings can deflect during hard cornering, braking and track use, allowing unwanted camber and toe change through the rear suspension. This movement can reduce confidence, consistency and feedback, particularly on fast road, track day and Clubsport builds where maintaining accurate suspension geometry is critical.

Fall Line’s solution is CNC-machined in the USA using DMG Mori 5-axis machining and full stainless steel bearing components, including the hats, bearings, housings and spiral locks. The result is a robust direct replacement designed to maintain alignment more consistently throughout suspension travel, helping maximise rear-end grip and driver confidence.

As with any spherical bearing upgrade, an increase in NVH should be expected compared with the factory rubber bushings. These are performance-focused components best suited to owners who prioritise sharper response, improved feedback and more precise rear suspension control over standard road-car refinement.

Supplied as a complete set of four bearings, with two per side, this kit is suitable for BMW G8X M2, M3 and M4 applications as well as F8X M2, M3 and M4 models.

FAQs

Are Fall Line Rear Upper Control Arm Bearings suitable for the BMW G80 M3 and G82 M4?

Yes. These Fall Line rear upper control arm bearings are compatible with BMW G80/G81 M3, G82/G83 M4 and G87 M2 models, as well as F8X M2, M3 and M4 applications.

What do rear upper control arm bearings do?

Rear upper control arm bearings help locate the rear suspension arms more precisely. By replacing the factory rubber bushings with spherical bearings, they reduce unwanted suspension flex and help maintain more consistent camber and toe under load.

Why upgrade from the factory BMW rubber bushings?

The OEM rubber bushings can flex during hard cornering, braking and track use. This can allow unwanted geometry change at the rear axle, reducing feedback, stability and consistency. Fall Line’s spherical bearing upgrade helps create a more planted and predictable rear end.

Will these bearings improve handling on track?

Yes. By reducing compliance in the rear upper control arms, these bearings help improve rear-end stability, alignment control and steering feedback during fast road and track driving.

Will they increase NVH?

Yes. As with most spherical bearing upgrades, some increase in noise, vibration and harshness should be expected. These are performance-focused suspension components designed for drivers who prioritise precision and feedback over factory refinement.

What is included in the kit?

The kit includes a complete set of four rear upper control arm bearings, with two bearings per side. The assemblies use stainless steel components including the hats, bearings, housings and spiral locks.

Are these a direct replacement for the original BMW bushings?

Yes. They are designed to replace the inner bushings on the rear upper control arms.
