Bilstein B12 Pro-Kit Suspension Upgrade for BMW X3 E83 2003 to 2011 - Part Number 46-189547

Transform the way your first-generation BMW X3 drives with this matched spring and damper package. The Bilstein B12 Pro-Kit teams Bilstein B8 sport dampers with Eibach progressive-rate coils to deliver confident cornering, a lower centre of gravity and a purposeful stance, all while keeping daily usability intact. Expect precise steering feel, strong body control and excellent ride quality on British roads.

We have installed this kit on E83 models and the results speak for themselves. Customers consistently report a tighter, more planted X3 with reduced roll and better stability at speed. If you are searching for a BMW X3 E83 suspension upgrade, a shock and spring combo that actually works on UK tarmac, or the Bilstein set with Eibach progressive springs, this is the proven choice.

Why this spring and damper set stands out

• Engineered pairing - Bilstein B8 shortened, gas-pressure dampers matched to Eibach progressive coils for balance, grip and confidence.
• Ride height reduction - typically up to 10 mm to 30 mm depending on vehicle specification, giving your X3 a sportier look and lower roll centre.
• Real-world performance - sharper turn in, flatter cornering and high-speed composure without the harshness associated with cheap coilovers.
• Monotube technology - consistent damping and fade-resistant control thanks to Bilstein gas-pressure monotube design.
• TÜV approved - independently certified for safety and quality.
• Built to last - OE-level materials and durability from two leading German suspension specialists.
