Bilstein B4 Left-Hand Front Damper for BMW X1 E84 2009 to 2015 | Part 22-183873

Restore crisp ride control and factory-level comfort on your first-generation BMW X1 with this Bilstein B4 left-hand front suspension unit. Part number 22-183873 is a direct-fit, original-spec replacement for the left front corner on the E84 platform, delivering the balanced handling, precise steering feel and braking stability your X1 should have from new.

Built with Bilstein gas-charged twin-tube technology, this front LHS strut offers consistent damping across rough roads and high-speed motorway driving. We have installed these at MJ Modifications on customer cars and the feedback is brilliant: quieter over bumps, tighter body control, improved confidence in corners and an authentic OE feel without harshness.

Key reasons to choose this B4 front LHS unit

• Genuine Bilstein B4 left-hand front damper for the E84 X1 passenger side
• Direct-fit MacPherson leg that maintains original ride height and geometry
• Gas-charged, twin-tube design for stable rebound and compression control
• Sharpens steering response and reduces dive, squat and body roll
• Ideal fix for MOT advisories, leaking shockers, knocking noises and uneven tyre wear
• OE-quality construction trusted by enthusiasts, technicians and daily drivers

For a balanced setup, we recommend replacing both front units together. The matching right-hand front counterpart is Bilstein 22-183880.
