LEMFÖRDER 37857 01 Track Control Arm For BMW X5

LEMFOERDER 37857 01 Track Control Arm – Precision Suspension Component

The LEMFOERDER 37857 01 Track Control Arm is a high‑performance suspension element engineered for the rear axle of BMW X5 models (F15, F85) produced between 2013 and 2018. This component serves as the upper right track control arm, ensuring optimal wheel alignment, stability, and handling characteristics under various driving conditions.

Key Functional Role

The Track Control Arm is a critical part of the vehicle’s suspension geometry. It connects the rear axle to the chassis, allowing controlled vertical movement while maintaining precise steering angles. By providing a stable pivot point, it:

• Maintains wheel camber during cornering and braking.
• Reduces body roll by limiting lateral wheel travel.
• Ensures consistent tire contact with the road surface, enhancing grip and safety.

Material Composition and Durability

The arm is fabricated from high‑strength aluminum alloy, chosen for its lightweight yet robust characteristics. This material offers:

• Superior corrosion resistance, extending service life in diverse climates.
• Reduced overall vehicle weight, contributing to improved fuel efficiency and handling dynamics.
• High fatigue strength, allowing it to withstand repetitive load cycles without failure.

Compatibility and Fitment

The LEMFOERDER 37857 01 is specifically designed for:

• BMW X5 (F15, F85) models from 2013 to 2018.
• Rear axle – right side – upper track control arm.
• Both standard and performance suspension setups within the specified model range.

Its dimensions and mounting points match OEM specifications, ensuring a seamless fit without the need for additional modifications.

Installation Overview

1. Preparation: Secure the vehicle on a lift or jack stands. Remove the rear wheel on the right side to access the suspension assembly.
2. Removal of Existing Arm: Detach the existing track control arm by loosening the mounting bolts and any associated bushings.
3. Installation of New Arm: Position the LEMFOERDER 37857 01 in place, aligning it with the chassis mounting points. Tighten all fasteners to manufacturer torque specifications.
4. Reassembly: Reinstall the wheel and lower the vehicle. Perform a final torque check on all bolts.
5. Alignment Check: After installation, conduct a professional wheel alignment to ensure optimal handling characteristics.

Performance Benefits

Upgrading to the LEMFOERDER 37857 01 Track Control Arm delivers noticeable improvements in driving dynamics:

• Enhanced cornering stability, reducing oversteer tendencies.
• Improved braking performance due to better tire contact and reduced wheel hop.
• Longer suspension component life, thanks to the high‑quality aluminum construction.

Maintenance Tips

While the arm itself requires minimal upkeep, regular inspection of surrounding components is advisable:

• Check for bushing wear and replace if necessary to maintain smooth suspension travel.
• Inspect mounting bolts for tightness during routine service intervals.
• Monitor tire pressure and alignment settings, as changes can affect arm performance.
