Keep your rear suspension tracking true with the Delphi control arm TC3663, a direct-fit replacement for the 2012-2015 BMW X1. This is the rear upper rearward control arm, which locates the suspension, maintains wheel alignment geometry, and carries the ball stud that lets the wheel move through its arc while the joint pivots.
OE-validated durability: tested to extremes for OE performance, withstanding temperatures below -40°C and over 120°C plus 720 hours of salt-spray exposure, with dimensional and material analysis for close OE-to-aftermarket compatibility.
100% inspected: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
Robot-welded: welding is robot-applied for consistent performance and quality.
Micron-tolerance ball studs: the ball studs are machined to micron tolerances for durable, smooth joint operation.
Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
Worn suspension arms or ball joints often show up as clunking over bumps, uneven tire wear, or wandering steering. If a failed control arm or its ball joint is the cause, this replaces it. Replace suspension components as directed by the vehicle service procedure and have the alignment set afterward.
