Rockplanet Front Suspension Control Arm Kit — E90 xDrive

Rockplanet builds these components with materials rated for both high-temperature resistance and high-wear durability — qualities that matter on a platform that routes torque to all four corners and sees constant lateral loading through the front suspension. Every piece receives an anti-corrosion treatment, a detail that pays dividends for owners in northern climates or anywhere road salt is a seasonal reality. These aren't bare-metal budget parts that start rusting in the wheel well after one winter.

Fitment spans a well-defined range of xDrive applications: 2006 BMW 325xi and 330xi, 2007–2008 335xi, 2009–2013 335i xDrive, 2012–2015 X1 xDrive28i, and 2013–2015 X1 xDrive35i. Rockplanet cross-references OEM part numbers including 31126768983, 31126768984, 31126768988, 31126768989, and 32106793621, among others, so you can verify fitment by comparing against the part numbers stamped on your existing components — the most reliable confirmation method before you start wrenching.

If you have any doubt about compatibility for your specific build date or production variant, Rockplanet recommends providing your VIN for verification before purchase. It's a small step that avoids the frustration of a return, and it reflects the kind of fitment-first approach that makes a suspension kit worth buying over piecemeal alternatives.
