Bilstein B1 12-303106 Front Strut Top Mount/Strut Bearing for BMW i3 I01 2013-on – EV, REx & i3s – MacPherson Upper Shock Mount/Guiding Support – Shock Tower Top Hat – OE Quality Front Suspension Mount

Bilstein B1 Upper Damper Mount - Part No. 12-303106

Upgrade the front end feel of your city EV with Bilstein’s B1 upper mounting unit. This genuine replacement guiding support restores crisp turn-in, smooth rotation and the refined cabin quietness you expect from a premium German chassis. It is engineered for the I01 platform across battery-only models and REx variants, including the i3s, from 2013 onwards.

If you are hearing knocks over bumps, feeling vague steering or noticing uneven tyre wear, the bearing plate at the top of the MacPherson assembly is likely tired. Swap to this Bilstein B1 component to bring back precise geometry, confident tracking and consistent contact patch control on UK roads.

Why this Bilstein mounting unit is a smart choice

• Original equipment-level durability and fit, built by Bilstein
• Designed to work perfectly with Bilstein dampers and factory shock absorbers
• Quiets creaks and rattles from a worn top bearing, improves steering response
• Ideal to install at the same time as springs, dampers or support bearings
• Direct replacement at the front, no modifications required

What it does

The top support and integrated bearing allow the strut to turn freely while isolating noise and vibration. As the part wears, you may experience play at the wheel, tramlining and nuisance noises. Fresh Bilstein hardware restores proper alignment control and refinement.

• I01 chassis 2013 onward
