Elring WHT 004 982 Turbocharger Lock Nut Wastegate Actuator Fastener

The Elring WHT 004 982 is a precision-engineered turbocharger lock nut designed to meet the exact specifications of Volkswagen Audi Group (VAG) turbocharged engines. Manufactured by Elring, one of Europe's most respected suppliers of OEM-quality engine components, this lock nut provides a reliable, vibration-resistant fastening solution for turbocharger assemblies.

Turbocharger lock nuts play a critical role in maintaining the correct positioning and tension of turbocharger components — such as the wastegate actuator rod or variable nozzle turbine (VNT) linkage — under the extreme heat and mechanical stress generated by forced-induction systems. Using the correct OEM-specification hardware ensures proper torque retention and prevents premature loosening that can lead to boost control issues or turbocharger damage.

Key Features:

• OEM-equivalent quality manufactured by Elring, a trusted Tier-1 European supplier
• Engineered to withstand high-temperature and high-vibration turbocharger environments
• Precision dimensions for correct fit and proper torque specification compliance
• Direct replacement for VAG OEM part number WHT 004 982
