Lemforder 1313801 Steering Rod Assembly

Lemforder 1313801 Steering Rod Assembly

The Lemforder 1313801 Steering Rod Assembly is a high‑performance component designed for the front axle of BMW and ALPINA vehicles, particularly models such as the E39 series (5‑Series Limousine, Touring, B10, D10). This assembly provides precise steering control and durability under demanding driving conditions.

Key Features

• Exact Fitment: Engineered to match the original specifications of BMW/ALPINA front‑axle geometry, ensuring seamless integration with existing suspension and steering systems.
• Robust Construction: Made from premium alloy steel, the rod assembly offers exceptional strength while maintaining a lightweight profile for optimal vehicle dynamics.
• Precision Machining: Each component is machined to tight tolerances, guaranteeing smooth operation and minimal play in the steering mechanism.
• Corrosion Resistance: Surface treatment protects against rust and wear, extending service life even in harsh environmental conditions.
• Compatibility: Suitable for both left‑hand drive (LHD) and right‑hand drive (RHD) configurations across a range of BMW/ALPINA models.

Technical Specifications

Installation Overview

The assembly replaces the original steering rod and its associated components (such as tie‑rod ends, bushings, and mounting brackets). Installation typically involves:

1. Removal of Old Rod: Detach the existing steering rod from the steering rack and wheel hub.
2. Preparation: Clean all mating surfaces to ensure proper contact and alignment.
3. Mounting: Secure the new assembly using supplied fasteners, ensuring torque specifications are met.
4. Alignment Check: Verify steering geometry (camber, caster, toe) remains within manufacturer tolerances.
5. Test Drive: Conduct a short test drive to confirm smooth steering response and absence of play or noise.

Performance Benefits

• Enhanced Steering Precision: The high‑quality construction reduces flex, providing sharper turn feel.
• Improved Durability: Resistant to fatigue and corrosion, the assembly withstands long‑term use without degradation.
• Reduced Maintenance: Fewer moving parts and robust materials lower the need for frequent inspections or replacements.
• Optimized Vehicle Dynamics: Lower unsprung mass contributes to better handling and ride comfort.

Compatibility Summary

The Lemforder 1313801 Steering Rod Assembly is specifically tailored for the following vehicle families:

• BMW E39 5‑Series Limousine (LHD/RHD)
• BMW E39 5‑Series Touring (LHD/RHD)
• BMW B10 and D10 models (LHD/RHD)
• ALPINA variants of the above BMW models

It is not intended for use in non‑E39 platforms or vehicles with differing steering rack geometries.

Maintenance Tips

• Inspect tie‑rod ends and bushings annually for wear or damage.
• Check torque on all mounting bolts after the first few hundred miles of operation.
• Avoid excessive steering input forces that could overstress the assembly.

Conclusion

The Lemforder 1313801 Steering Rod Assembly delivers a blend of precision engineering, durable materials, and exact fitment for BMW/ALPINA front‑axle systems. Whether restoring an older vehicle or upgrading performance components, this assembly ensures reliable steering control and long‑term reliability.
