About this product
Sourced from AIC, this nut (50979) combines precision engineering with durable materials to meet the demands of everyday driving and extended service intervals. Technical specifications — Fitting Position: Front Axle, Thread Size: M 12 x 1, Rubber, Spanner Size: Synthetic, Bolt/Nut Version: 33 — are verified against the OEM data sheet to guarantee fitment accuracy and performance parity with the original equipment. This part supersedes original equipment references: 05139, 104 530, 30 90 5139, N 903 237 01 and 3 more. Matching these numbers confirms a like-for-like replacement with no loss of function. AIC 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 from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.
