Bilstein B1 12-303113 Rear Right Offside Upper Shock/Strut Top Mount Support Bearing (Top Hat/Bearing Plate) for BMW i3 I01 2013-on incl i3s BEV & REx/Range Extender | OE Damper Mount RH RHD

Bilstein 12-303113 Rear Offside Upper Damper Mount for BMW i3 I01

Refresh the back end of your BMW i3 with the Bilstein 12-303113 rear offside upper mount. This OE-spec mounting plate and bearing assembly is engineered for the I01 chassis from 2013 onward, covering both Battery Electric models and Range Extender variants including i3s. Expect crisp handling, quieter operation and a tight, factory-fresh feel from a brand trusted by enthusiasts and technicians.

Tired of knocks, creaks and vague rear-end behaviour over bumps or during cornering. A tired upper shock mount is a common culprit. Swap in this Bilstein unit to reduce NVH, stabilise the rear axle and protect your shock absorber performance. We run these on our own workshop cars and customer builds, and feedback has been consistently positive for ride quality, steering response and longevity.

Key benefits

• Exact-position fitment for the rear offside on I01 platform cars for a straightforward replacement.
• Factory-equivalent durability and geometry to maintain correct suspension alignment and damper function.
• Improves refinement by helping eliminate clunks and squeaks while sharpening turn-in and stability.
• Designed to work perfectly with OE shock absorbers and Bilstein dampers.
• Built for daily road use with the robust quality that performance-focused owners expect.

Best practice

For balanced handling, many owners replace both rear upper mounts together. The matching nearside partner is Bilstein 12-303120.
