Febi Bilstein 40103 Front Lower Control Arm with Bushes, Ball Joint, Bracket & Hardware

The Febi Bilstein 40103 is a complete front lower control arm assembly for the left side of the front axle. Manufactured from cast steel, this suspension wishbone (also referred to as a track control arm) is a direct OE-quality replacement for Audi, Seat, Skoda, and Volkswagen applications. The kit includes pre-installed bushings, a ball joint, mounting bracket, lock nut, and bolts — everything required for a complete, professional installation.

Control arms serve as the critical link between the suspension strut and the vehicle chassis. They maintain proper wheel alignment and absorb the longitudinal and transverse forces generated during acceleration, braking, and cornering. The arm must also articulate up and down to accommodate suspension travel.
