Notes

• Identified as 'Blue' in the Mercedes-Benz EPC — do not confuse with the centre 'Red' sphere (A 126 320 07 15)
• On the W116 450SEL 6.9 this part fits the rear positions only (2 required); on the W126 hydropneumatic this part fits both front and rear positions (4 required)
• Febi Bilstein is a trusted OE-quality European supplier
• Professional installation recommended — the hydropneumatic system operates under high pressure and requires depressurisation before sphere removal
• Superseded part number A 126 320 05 15 is no longer available from Mercedes-Benz; A 126 320 13 15 is the current replacement
• W126 fitment: confirm your vehicle has option code 487 before ordering — contact us with your VIN or data card if unsure
