Lemförder 38311 01 Suspension Arm

Lemförder 38311 01 Suspension Arm

The 38311 01 Suspension Arm from Lemförder is a high‑performance component engineered for the front axle of select BMW models, including the X5, X6, E70, E71, and E72 series. Designed to replace or repair the original suspension arm, this part delivers precise geometry, durability, and seamless integration with the vehicle’s existing chassis.

Key Design Features

• Exact Geometry Matching: The arm is manufactured to match the OEM specifications for wheel alignment angles, camber control, and load distribution. This ensures that the vehicle retains its original handling characteristics after replacement.
• High‑Strength Material: Constructed from a proprietary alloy blend, the suspension arm offers superior tensile strength while maintaining a lightweight profile. The material resists fatigue and corrosion over extended service life.
• Optimized Surface Finish: A smooth finish reduces wear on adjacent components such as bushings and mounting brackets, extending overall suspension longevity.
• Integrated Mounting Points: Pre‑drilled holes and precise tolerances allow for direct installation without the need for additional adapters or modifications.

Compatibility Overview

The 38311 01 arm is specifically engineered for the following BMW front axle configurations:

• X5 (E70)
• X6 (E71)
• E72 (X6)
• Other models with identical front‑axle geometry, such as certain MINI variants that share the same suspension architecture.

It is available for both left and right sides, ensuring symmetrical replacement across the vehicle. The part fits the lower interior mounting area of the front axle, providing a direct substitute for the original component.

Installation Guidance

1. Preparation: Secure the vehicle on a stable lift or jack stands. Remove the wheel and disconnect the brake caliper to access the suspension arm.
2. Removal of Original Arm: Loosen the mounting bolts, carefully detach the old arm, and note any alignment marks for reference.
3. Positioning the New Arm: Align the 38311 01 with the existing mounting points. Verify that the bolt holes match precisely to avoid misalignment.
4. Tightening Sequence: Tighten bolts in a cross‑pattern sequence, following manufacturer torque specifications (typically 80–100 Nm). Use a calibrated torque wrench for accuracy.
5. Reassembly: Reinstall the brake caliper and wheel. Lower the vehicle and perform an initial test drive to confirm proper operation.

Benefits of Choosing Lemförder 38311 01

• Restored Performance: By matching OEM geometry, the arm preserves handling dynamics, steering feel, and ride comfort.
• Enhanced Durability: The alloy construction resists cracking under high load conditions, making it suitable for both daily driving and spirited use.
• Reduced Maintenance: A smooth surface finish minimizes wear on adjacent bushings, reducing the frequency of component replacement.
• Easy Replacement: The design allows for straightforward swap‑in installation without extensive machining or custom fitting.

Maintenance Tips

Although the suspension arm itself requires minimal upkeep, regular inspection of surrounding components is recommended:

• Check bushings and ball joints for signs of wear or damage.
• Ensure that all mounting bolts remain tight; re‑torque after a few hundred miles.
• Inspect the wheel alignment periodically, especially if the vehicle experiences uneven tire wear.
