About this product
When gas spring bonnet performance matters, the FEBI BILSTEIN 34514 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Fitting Position: FB, Length [mm]: 413 mm, Weight [kg]: 0, 197 kg, Stroke [mm]: 101 mm, Extention Force [N]: 390 N. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. Compatible with BMW vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 08.63.030, 09010473, 09010475, 101-00-309 and 78 more. Matching these numbers confirms a like-for-like replacement with no loss of function. FEBI BILSTEIN is a recognised supplier of automotive suspension components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops.
