Improve cornering balance and handling response with the Eibach E40-20-031-01-11 Anti-Roll Kit. Designed for select BMW 3 Series and 4 Series applications, this performance suspension upgrade helps reduce body roll during cornering while maintaining predictable, controlled vehicle behavior. The kit combines a tubular, two-way-adjustable front sway bar with a solid, non-adjustable rear sway bar for a balanced performance setup.

The front bar offers two adjustment positions, allowing drivers and installers to fine-tune handling characteristics for street performance, spirited driving, or track-focused setups. Its tubular construction provides strength with reduced weight compared with many conventional solid designs. The solid rear bar complements the front assembly by adding roll resistance and helping improve chassis response through turns. Eibach engineering delivers a coordinated anti-roll solution intended to work with the factory suspension geometry on compatible BMW models.

This Eibach anti-roll kit fits select 2012–2018 BMW 335i, 340i, and 435i models, including F30 and F32 chassis applications. Verify the vehicle year, model, chassis, and existing suspension configuration before installation. Professional installation is recommended, followed by an alignment and appropriate suspension inspection. The kit is intended for automotive use and is supplied as a matched front and rear sway bar package.
