ECS Heavy Duty Front Headlight Leveling Sensor Rod (31122282404) - E46 M3
Over time, road grime, salt, and moisture take a toll on the factory rear leveling rod. The original equipment often corrodes, seizes, and eventually snaps—or worse, binds up and breaks your expensive headlight leveling sensor. With this issue in mind, we've engineered a heavy-duty, bulletproof solution designed to outlast the car it’s installed on.
To provide a cost-effective yet durable solution, ECS engineered a replacement rod using high-strength, flexible polyurethane. Paired with corrosion-resistant stainless steel ball studs, it guarantees smooth articulation and prevents the binding that destroys expensive sensors. Precision-manufactured for a perfect, bolt-on fit, this upgrade requires zero modifications to replace your fragile OEM unit.
This is a direct-fit replacement for Genuine BMW part number 31122282404, restoring proper suspension-to-sensor geometry so your headlights adjust perfectly to changing loads and road conditions.
