Proper clamping of the front engine mount requires both the top and bottom fasteners to be in good condition. The genuine Nissan Front Engine Motor Mount Nut (part number 01225-00521) is the factory bottom nut used on the Fairlady Z / 300ZX Z32 to secure the front engine mount from below.
This OEM nut is manufactured to the correct thread size, strength grade, and finish specified by Nissan for this location. Over time the original bottom nut can become corroded, rounded, or damaged during mount replacement or underbody service. Replacing it with the genuine Nissan part ensures the mount is fastened to the proper torque specification and maintains the intended support and alignment for the VG30 engine. These nuts are commonly needed whenever the front engine mount is removed or renewed.
Whether you are completing a full engine mount service, replacing worn hardware, or performing related chassis work, using the correct OEM bottom nut helps achieve a secure and correctly positioned installation. At Terra Firma Automotive, we supply this genuine Nissan Front Engine Mount Bottom Nut for Z32 owners who prefer authentic fasteners. Choose Terra Firma Automotive for correct-fit Nissan hardware that supports proper engine mounting on the Fairlady Z and 300ZX.
