Frequently Asked Questions

Is this for the driver's side or the passenger's side?
This specific control arm (31127850157) is engineered strictly for the Left Side of the vehicle (which is the Driver's Side on Left-Hand Drive vehicles in North America and Europe). The suspension geometry is highly asymmetrical, meaning you cannot use this arm on the right side.
Should I replace the right side at the same time?
Highly Recommended. If the stiff M-spec bushings or the outer ball joint on your left arm have failed from age and stress, the right side has endured the exact same mileage, immense vehicle weight, and punishing road conditions. Replacing both lower wishbones simultaneously ensures your suspension geometry remains perfectly balanced and prevents you from having to pay for a second wheel alignment down the road.
Will this fit my standard X5 50i or X6 with the "M-Sport" package?
No. The full-blooded "M" models utilize completely different, heavily reinforced control arms, much stiffer solid-rubber bushing compounds, and altered suspension geometry to handle their massive track-focused cornering loads. This specific arm is strictly for the true F85 X5 M and F86 X6 M vehicles. It will not bolt up correctly to standard F15/F16 chassis models, even if they have M-Sport aesthetics.
Do I need a wheel alignment after installing this arm?
Absolutely. Anytime you replace a primary structural component of your double-wishbone suspension—especially the lower arm that dictates camber and supports the shock assembly—the vehicle's alignment geometry will drastically shift. To prevent your wide, expensive high-performance M tires from wearing unevenly, a professional alignment is mandatory immediately after installation.
