Technical specifications — Height [mm]: 21 mm, Weight [kg]: 0, 203 kg, Machining: Steel, Inner Diameter [mm]: 115 mm, Outer Diameter [mm]: 120 mm — are verified against the OEM data sheet to guarantee fitment accuracy and performance parity with the original equipment. This part supersedes original equipment references: 010.040-00A, 030.401-00A, 07720, 100.055/1 and 14 more. Matching these numbers confirms a like-for-like replacement with no loss of function. AUGER is a recognised supplier of automotive replacement 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. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price. Every part is dispatched with tracked delivery and a 14-day money-back guarantee with hassle-free returns.
