BMW Control Arm Replacements & Upgrades for BMW X5 M S63 4.4L

Please ensure your correct model is selected

Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. They do more than just keep the alignment in a constant spec - they are a vital locating component for the suspension itself. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals.

Most control arms for BMWs consist of an inner and outer ball joint made of plastic, rubber, Delrin, or metal and covered in grease with a rubber boot to seal it from the outside. The ball joint rotates and spins as the control arm goes through its movements and that will wear the ball joint and make it loose. The grease inside the housing can also get used up, evaporate, or become contaminated from moisture and foreign particles. As the ball joint becomes worn it can result in excess movement within the housing. Your steering and handling will become less precise and there is usually a light clunking or clicking sound. In rare and extreme cases the ball joint can separate from the control arm completely, leading to a total loss of suspension and steering control. You should have the ball joint play checked annually and replace them every 3-4 years. Most track organizations will not allow a car if they are older than three years.

Control arms also take abuse from impacts and handling forces. Aluminum control arms will generally bend and prevent an accurate alignment. Steel control arms will crack and fracture and require close inspection annually and replacement every 3-4 years.

We sell OE BMW, OEM, and performance upgrade control arms from proven manufacturers. The control arm is so important to a BMW suspension that we insist on only top quality brands and designs and will never sell a control arm based on price alone. We also have upgrade packages with superior designs and better bushing options and we have bundled these together with valuable package savings.

Control arm bushings play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

BMW’s are known to have failure prone front thrust arm bushings. The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change. This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience. Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure. For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available! Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011). We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise. We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting. The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment. What you get is superior steering precision, turn-in response, direct braking feedback, and better handling. In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered. We offer these thrust arms with the monoball bushings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms. Features: Bearing housing Precision CNC machined from 6061-T6 blue anodized aluminum Knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands. CNC machined 304ss ball joint sleeve inserts, providing a precision fit between the ball joint and the subframe. Bearing OEM BMW sealed and greased ball joint for exceptional durability and service life. Performance Nearly instantaneous, crisp steering and braking response. Maintenance free, long lasting performance. Improved road feel without undesirable NVH.
