Maintain secure, factory-correct fastening on your Nissan Patrol ZD30 turbo and exhaust system with this Genuine Nissan Lock Nut, designed for GU Y61 models fitted with the ZD30 engine. This OEM nut is used across multiple critical mounting points, including the turbo to exhaust manifold, manifold to EGR pipe, and dump pipe connections depending on model year.

Over time, factory nuts can corrode, seize, or lose clamping effectiveness due to extreme heat cycles and exhaust system stress. A worn or incorrect nut can lead to exhaust leaks, boost loss, ticking noises, and reduced turbo efficiency.

Manufactured to Nissan’s original specifications, this direct-fit replacement ensures proper torque retention, heat resistance, and long-term reliability in high-temperature exhaust applications.
