Whiteline Plus Front Control Arm Upper Inner & Outer Bushing Kit for Select BMW 2005-2015 (W63403)

Fits select 2005-2015 BMW 1 Series, 3 Series, and X1 models.

Degraded or failed control arm bushings often lead to uneven tire wear, unbalanced braking, and an unpredictable rear end during cornering. The Whiteline Plus W63403 kit replaces worn factory components with high-performance synthetic elastomer bushings designed for long-lasting durability and a more predictable handling profile.

Each bushing features a specially bonded design for optimized strength under high load-bearing applications. The synthetic elastomer formulation is resistant to oil, grease, ozone, and weathering, ensuring performance does not degrade over time. To ensure consistent operation and low friction, these bushings include internal grease reservoirs and are supplied with molybdenum disulphide (LM) based grease for extended service life.
