About this product
When track rod set performance matters, the RODRUNNER AJ-A-512K 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: Front Axle, Length [mm]: 240 mm, Width [mm]: 72 mm, Height [mm]: 72 mm, Weight [kg]: 0, 678 kg. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 24-06078K, 44-03657K, 4D0422821A, 8E0422821C and 3 more. Matching these numbers confirms a like-for-like replacement with no loss of function. RODRUNNER 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.
