Keeps your ALFA ROMEO running the way it should — this Aftermarket part restores the original function of a worn or failed Front Left Right Driveshaft Axle Nut OE Ref 71753817, built to OEM reference KLPAR004Z rather than a generic approximation.
Aftermarket identifies it as AMCP-5109-AR004Z. Match that against OEM KLPAR004Z or your old part before fitting, particularly if your vehicle's had any running changes across its production years.
Confirmed for selected ALFA ROMEO vehicles. Use the vehicle registration lookup tool if you're not certain, or browse Driveshaft & CV Joint for other options.
