Bilstein B12 Pro-Kit 46-331304 for BMW 3 Series Touring F31 xDrive 2012–2019 (330d 335d diesel) – B8 Dampers + Eibach Pro-Kit Springs – Lowering 10–30mm – Estate/Wagon AWD 4x4 Sport Suspension, Shocks & Springs Coilover Alternative

Sport Spring and Damper Package for BMW F31 xDrive 330d and 335d

Give your 3 Series Touring a genuine handling upgrade with this matched shock and spring set. Part number BILSTEIN-46-331304 combines Bilstein B8 shortened-stroke gas pressure shock absorbers with Eibach progressive-rate springs for tighter body control, crisper steering response and a purposeful ride height reduction of approximately 10 to 30 mm depending on vehicle spec. It is the OEM-plus solution that looks right and drives even better on UK roads.

We have fitted this package on our own cars and for many customers, and the feedback is consistent: flatter cornering, improved stability under braking, confident high-speed composure and a refined ride that works brilliantly for daily use, fast road and motorway miles.

Why this setup works

• Matched components: Bilstein B8 performance shock absorbers tuned to Eibach springs for balanced control and comfort
• Improved turn-in and reduced roll without the harshness associated with cheap coilovers
• Gas pressure monotube technology for consistent damping and excellent fade resistance
• German TÜV approved quality with direct bolt-on fit for F31 xDrive diesel models
• Set and forget simplicity with a clean, even stance

In the box

• 4x Bilstein B8 shortened-stroke performance shock absorbers
• 4x Eibach Pro-Kit progressive springs
• Vehicle-specific calibration for BMW F31 xDrive

Lowering range

Typical front and rear drop: approximately 10 to 30 mm, dependent on engine, equipment and current suspension condition.
