Front Control Arm

This OEM Lemforder Level 1 suspension rebuild kit for the E39 addresses the symptoms related to the included components in the front suspension. Common failure items here result in imprecise, wandering steering, or more commonly: the dreaded "death wobble" at 55mph.

Including all four front control arms with bushings, this kit is ideal for a car with tight suspension but with loose ball joints.

The Powerflex Front Control Arm Bushing Set (Front Position) for the BMW i3 offers improved suspension performance.

• Polyurethane Build: Provides greater durability and wear resistance compared to OEM rubber bushings.
• Better Handling: Reduces flex in the control arms, leading to more precise steering and stability, especially in corners.
• Direct Fit: Easy to install as a replacement for the factory bushings.
• Comfort Retained: Balances performance with ride comfort, ideal for daily driving.

Perfect for BMW i3 owners seeking enhanced steering response and longer-lasting suspension components.

Ensure optimal performance and safety for your BMW with Turner Motorsport Lemforder Front Lower Control Arm (part number 31126851691). Over time, road hazards and wear can lead to a weak and sloppy suspension, affecting steering precision and ride comfort. Worn-out control arm ball joints can cause steering wobble and clunking, compromising driving experience and safety. Replace worn components promptly to restore tight steering and improve ride comfort. Here are the key benefits:

• Enhances steering precision and feel
• Improves safety by preventing steering wobble and clunking
• Restores ride comfort and stability
• Ensure proper suspension performance and longevity

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.

Control arms 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. 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. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.

OEM Lemförder is an engineering company that focuses on high-quality, precision manufacturing of critical suspension and steering components. Providing exceptionally high quality parts directly to BMW, as well as 50+ other big name automotive companies, such as Mercedes and Audi, their history of reliability and variety of offered parts makes them one of the biggest names for a go-to OEM parts provider. Lemförder parts place an important emphasis on design, production, and assembly, ensuring maximum reliability. They even coat all parts possible with corrosion protection for extended longevity.

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 goes back to those we designed and used in our IMSA E90 328i and E92 M3 race cars (GS class Champions in 2011). We wanted to offer as many BMW owners possible a similar level of handling, precision, and control for the track and street.

Utilizing 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 control arms with the monoball bearings 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.
