BMW Control Arm Replacements & Upgrades for BMW X Series F39 (2018+)

Clear BMW chassis

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.

The Powerflex Front Control Arm Rear Bushing (Caster Offset) for the BMW F48, F49 X1, and F39 X2 is a premium suspension upgrade designed to improve handling, steering feel, and suspension durability. These bushings replace the factory-installed rubber bushings, which are prone to wear and deflection over time, with high-quality polyurethane bushings that deliver enhanced performance and longevity.

Key Features:

Caster Offset Design:
- The bushing features a caster offset, meaning it slightly adjusts the position of the control arm to increase the vehicle’s caster angle. This improved geometry enhances the car's straight-line stability and helps maintain better steering feel during cornering. The result is sharper turn-in, better directional control, and a more responsive overall driving experience.
Superior Material – Polyurethane:
- Powerflex uses high-performance polyurethane, which is much more durable than standard rubber bushings. Polyurethane bushings resist degradation from oil, road grime, and temperature extremes, making them ideal for both daily driving and high-performance applications.
- Benefits of Polyurethane:
  - Reduced Flex and Deflection: Offers a firmer connection between the control arm and chassis, reducing unwanted movement in the suspension and improving steering accuracy.
  - Extended Lifespan: Compared to the stock rubber bushings, these will last significantly longer, making them a solid investment for long-term performance and reliability.
  - Improved Handling: The reduced flex and firmer construction mean that the suspension responds more precisely to driver inputs, improving overall handling and cornering stability.
Applications:
- BMW X1 (F48, F49): This model is BMW’s compact luxury crossover SUV. The Powerflex bushings provide better handling, making the X1 more responsive and stable, especially at higher speeds or during spirited driving.
- BMW X2 (F39): Known for its sportier, coupe-like stance, the X2 benefits from the improved geometry and stiffer bushing, resulting in even sharper steering and enhanced cornering ability, further emphasizing its sport-focused character.
Improved Caster Angle:
- The increased caster angle results in a more self-centering steering feel, providing better directional stability at high speeds, and enhancing control during cornering. This is especially beneficial for drivers who seek a more engaging driving experience or who use their BMW for spirited driving or track days.
Performance and Practicality:
- These bushings aren’t just for performance enthusiasts. Even for daily driving, they offer improvements in steering feedback and stability. The added durability ensures that your suspension components last longer, making it a worthwhile upgrade even for those who don’t push their cars to the limit.
Professional Installation Recommended:
- Installing these bushings requires removing the control arms and pressing out the old bushings. Since the caster offset alters the suspension geometry, a professional alignment is also recommended post-installation to ensure optimal performance.
