Proper fastening of the transmission mount to the crossmember is essential for driveline stability and reduced vibration. The genuine Nissan Transmission Crossmember to Transmission Mount Nut (part number 08918-6081A) is the factory nut used on the Fairlady Z / 300ZX Z32 to secure the transmission mount to the crossmember.
This OEM nut is manufactured to the correct thread size, strength grade, and finish specified by Nissan for this application. Over time original nuts can become corroded, rounded, or lost during transmission, exhaust, or underbody service. Replacing them with the genuine Nissan part ensures the mount is fastened to the proper torque specification and maintains the intended clamping force. These nuts are commonly required when the transmission crossmember or mount is removed for service or replacement.
Whether you are reassembling after a transmission job, replacing worn hardware, or performing related chassis work, using the correct OEM nut helps maintain a secure and correctly aligned installation. At Terra Firma Automotive, we supply this genuine Nissan Transmission Mount Nut for Z32 owners who prefer authentic fasteners. Choose Terra Firma Automotive for correct-fit Nissan hardware that supports proper driveline mounting on the Fairlady Z and 300ZX.
