LEMFÖRDER 37684 01 Track Control Arm For BMW X5

LEMFÖRDER 37684 01 Track Control Arm – Precision Suspension Component for the BMW X5

The LEMFÖRDER 37684 01 Track Control Arm is a high‑performance suspension part engineered specifically for the BMW X5 series. Designed to replace the original front upper control arm, this component delivers superior handling dynamics, improved wheel alignment stability, and enhanced durability under demanding driving conditions.

Key Features & Technical Highlights

• Exact OEM Fitment: Manufactured to match the exact specifications of the BMW X5 (F15/F85) front upper control arm, ensuring seamless integration with existing suspension geometry.
• High‑Strength Construction: Made from premium alloy steel and subjected to rigorous heat treatment processes. This results in a component that can withstand high torsional loads while maintaining low weight.
• Optimized Geometry: The arm’s shape is engineered to reduce camber change during suspension travel, providing consistent tire contact patches and improving cornering performance.
• Corrosion‑Resistant Finish: A protective coating resists rust and corrosion, extending the life of the control arm even in harsh climates or road salt environments.
• Pre‑Aligned Mounting Points: The bolt holes are positioned to match OEM alignment tolerances, eliminating the need for additional shims or adjustments during installation.

Compatibility Overview

This track control arm is compatible with a wide range of BMW X5 models across multiple generations:

• X5 (F15/F85) – 2013 to 2018 (Front Upper Control Arm, Right Side)
• X5 (E70) – 2006 to 2013 (Upper Front Suspension Arm, Right/Left)
• Other BMW vehicles that share the same suspension architecture, such as certain X6 and M models.

Installation & Maintenance Guide

Installing the LEMFÖRDER 37684 01 track control arm is a straightforward process for experienced mechanics or knowledgeable DIY enthusiasts. Follow these steps to ensure proper fitment:

1. Preparation: Raise the vehicle securely using jack stands and remove the front wheel on the side where the new arm will be installed.
2. Remove Old Arm: Detach the existing control arm by loosening the mounting bolts. Carefully disconnect any associated tie‑rod or sway bar links if necessary.
3. Position New Arm: Align the LEMFÖRDER track control arm with the suspension frame, ensuring that the bolt holes match the original positions exactly.
4. Tighten Bolts: Secure the new arm using a torque wrench. Follow BMW’s recommended torque specifications (typically around 120–140 Nm for upper control arm bolts).
5. Reinstall Wheel & Lower Suspension: Replace the wheel, lower the vehicle, and recheck all fasteners.
6. Alignment Check: After installation, perform a professional wheel alignment to confirm that camber, caster, and toe settings are within factory tolerances.

For routine maintenance, inspect the control arm for signs of wear or damage during regular suspension checks. Replace if any deformation, cracking, or excessive play is observed.

Performance Benefits

• Enhanced Handling: The precise geometry reduces unwanted camber changes, leading to more predictable steering response and improved grip during cornering.
• Longer Component Life: High‑quality materials and protective coatings mean the arm can endure repeated stress cycles without fatigue or corrosion.
• Consistent Ride Comfort: By maintaining proper wheel alignment, the control arm helps preserve suspension damping characteristics, ensuring a smooth ride over uneven road surfaces.
