Product Details

• Article Number: 273C1499 — Ridex lower-rear control arm for the front-left position. Mirror counterpart to the 273C1444 right arm — these two parts form a matched pair on the BMW X3 F25 lower-rear front suspension.
• Control / Trailing Arm Type: Control Arm — lateral suspension link controlling caster angle and resisting braking-force rotation of the wheel hub.
• Material: Cast Steel — heavy-duty forged/cast construction capable of withstanding repeated high-load events from braking and impact.
• Length: 298 mm — matches the 273C1444 dimension exactly — both arms must be identical for proper suspension geometry on both sides.
• Thread Size 1: M14×1.5 — metric fine-pitch ball joint thread specification.
• Diameter 1: 12.2 mm — ball joint stud diameter specification. Critical for correct seating and torque retention.
• Fitting Position: Front Axle, Left, Lower, Rear — the rear-lower position on the driver's side of the front axle (LHD convention). Four-way positional specification — not interchangeable with any other suspension arm.
• Condition: New — factory-sealed in Ridex packaging.
• Manufacturer: RIDEX — AUTODOC's in-house OEM-equivalent aftermarket brand, produced in quality-certified factories to IATF 16949 automotive standards.
• OEM Cross-References: BMW 31 12 6 787 669, BMW 6 787 669 — direct equivalents to these original BMW part numbers.
• Vehicle Compatibility: Designed for BMW X3 F25 (2010 onwards) and BMW X4 F26 (2014 onwards). Always verify against your vehicle's VIN or existing part number before purchasing.
• Full Set Recommendation: For best results, replace all four front lower arms as a complete set: 273C1415 (upper left), 273C1418 (upper right), 273C1444 (lower right rear), and 273C1499 (lower left rear). A professional wheel alignment is mandatory after installation.
