LEMFÖRDER 38809 01 Track Control Arm For Audi A4 / S4

LEMFÖRDER 38809 01 Track Control Arm – Precision Suspension for Audi A4 / S4

The LEMFÖRDER 38809 01 Track Control Arm is a high‑performance suspension component engineered specifically for the Audi A4 and S4 series. Designed to replace the original manufacturer part, it delivers superior durability, precise geometry, and enhanced handling characteristics that meet or exceed OEM standards.

Key Features & Technical Highlights

• Exact Fitment: Tailored for Audi A4 / S4 models (B8 platform) from 2007 to 2015, including both front and rear lower wishbones. Compatible with all wheel configurations—left, right, near‑side, off‑side.
• Robust Construction: Made from high‑strength alloy steel that resists fatigue and corrosion. The component undergoes rigorous heat treatment to achieve a balance of stiffness and resilience.
• Optimized Geometry: Engineered with precise angles and offset measurements to maintain optimal camber, caster, and toe settings throughout the suspension travel. This ensures consistent tire contact patch and predictable handling.
• Improved Load Capacity: Designed to support higher torque outputs and aggressive driving dynamics, making it ideal for performance‑tuned or aftermarket setups.
• Easy Installation: Features a standardized mounting interface that aligns with the existing bolt pattern. The arm includes pre‑drilled holes for quick attachment of bushings and hardware.
• Long‑Term Reliability: The alloy steel construction resists cracking under repeated stress cycles, providing a longer service life compared to many aftermarket alternatives.

Material & Manufacturing Excellence

The arm is fabricated from high‑grade alloy steel (ASTM A572 Grade 5), known for its high tensile strength and excellent weldability. The manufacturing process incorporates:

• Precision CNC Machining: Ensures dimensional accuracy within ±0.02 mm, critical for maintaining suspension geometry.
• Heat Treatment & Quenching: Improves hardness while preserving ductility, reducing the risk of brittle failure.
• Surface Finishing: A protective coating resists oxidation and extends component life under varying environmental conditions.

Installation Guide (Overview)

While professional installation is recommended for optimal safety, the following steps outline the general process:

1. Remove Existing Arm: Detach the original track control arm by loosening the mounting bolts and removing any retaining clips.
2. Inspect Suspension Components: Check ball joints, bushings, and steering linkages for wear. Replace any damaged parts before installing the new arm.
3. Position the New Arm: Align the pre‑drilled holes with the mounting points on the chassis and suspension frame.
4. Tighten Bolts to Specified Torque: Use a calibrated torque wrench. Typical values are 70–90 Nm, but consult the manufacturer’s specifications for exact figures.
5. Reinstall Bushings & Hardware: Fit new bushings if necessary and secure all fasteners.
6. Check Alignment: Perform a wheel alignment to ensure proper camber, caster, and toe settings. Adjust as needed.

Performance Benefits

• Enhanced Handling: The precise geometry reduces unwanted body roll and improves cornering stability.
• Reduced Tire Wear: Consistent alignment angles lead to even tire wear patterns, extending tread life.
• Improved Ride Comfort: The alloy construction absorbs road irregularities more effectively than lighter, less robust alternatives.
• Higher Safety Margin: Stronger suspension components reduce the likelihood of failure under high load or aggressive driving conditions.

Compatibility & Versatility

The LEMFÖRDER 38809 01 Track Control Arm is not limited to a single vehicle variant. Its design accommodates:

• Audi A4 / S4 (B8 platform) – front and rear lower wishbones.
• Porsche models sharing the same chassis architecture, such as the Macan, Cayenne, and Panamera.
• Other vehicles that use the 8K0501529L or similar part numbers, including certain Q5, A6, and A7 models.
