Lemförder 38396 01 Suspension Arm

Lemförder 38396 01 Suspension Arm

The Lemforder 38396 01 suspension arm is a precision‑engineered component designed to enhance the handling and ride quality of BMW vehicles. Crafted from high‑strength alloy, this part delivers durability while maintaining lightweight characteristics essential for optimal vehicle dynamics.

Key Features

• Material Excellence: Made from aerospace‑grade aluminum alloy, offering a superior strength‑to‑weight ratio that reduces unsprung mass and improves suspension response.
• Precision Machining: Each arm undergoes CNC machining to achieve tight tolerances, ensuring flawless fitment on the original chassis.
• Corrosion Resistance: Surface treatment provides long‑term protection against rust and environmental degradation, extending component life.
• Compatibility: Specifically engineered for BMW models including the 3 Series (E90/E91/E87), Touring (E91), Coupe (E92), and Mini variants that use the 38396 01 reference.
• Enhanced Handling: By reducing flex in the suspension geometry, this arm improves steering precision and reduces body roll during cornering.

Technical Specifications

Installation Overview

The installation of the Lemforder 38396 01 suspension arm follows a straightforward procedure that can be completed with standard automotive tools. Below is an outline of the steps involved:

1. Preparation: Secure the vehicle on jack stands and remove the wheel to access the suspension assembly.
2. Removal of Old Arm: Loosen the mounting bolts using a torque wrench set to 30 Nm, then detach the old arm. Keep all hardware for reuse if desired.
3. Alignment Check: Inspect the steering knuckle and control arms for wear or damage; replace any compromised components before proceeding.
4. Mounting New Arm: Position the Lemforder 38396 01 onto the steering knuckle, aligning the bolt holes precisely. Insert bolts and hand‑tighten.
5. Tightening Sequence: Follow a crisscross pattern to apply torque in increments of 10 Nm until reaching the final 30 Nm specification.
6. Reassembly: Reinstall the wheel, lower the vehicle, and perform a test drive to confirm proper alignment and handling characteristics.

Benefits for Vehicle Dynamics

Replacing worn or stock suspension arms with the Lemforder 38396 01 yields noticeable improvements:

• Reduced Unsprung Mass: Lighter arm weight decreases inertia, allowing the suspension to react more quickly to road irregularities.
• Improved Steering Feel: Stiffer geometry reduces flex, providing a tighter connection between wheel movement and steering input.
• Enhanced Ride Comfort: Consistent arm stiffness maintains optimal camber angles during compression and rebound cycles.
• Longevity: High‑quality materials resist fatigue, extending the service life beyond that of standard aftermarket options.
