Genuine part. Fitment information is for reference only. To ensure 100% compatibility, please send us a message with your VIN number before ordering.
Product Description
The genuine Nissan 01121-07211 fastening bolt is a critical drivetrain fastener that provides the structural connection between the engine block and the transmission bellhousing. It is engineered to withstand significant torsional, shear, and tensile forces generated during drivetrain operation, preventing micro-movement between the engine and transmission, excessive vibration, and clutch or bearing stress caused by misalignment.

Maintenance and Replacement Guide:
During transmission removal (such as clutch replacement, crankshaft rear main seal service, or gearbox overhaul), the mounting bolts are subjected to intense mechanical stress. Thread damage, stretching, or corrosion can lead to bolt loosening or shearing, which may cause bellhousing cracking, abnormal drivetrain noises, or shaft misalignment. It is recommended to strictly observe the manufacturer-specified tightening torque and replace damaged or fatigued fasteners with genuine OEM components.
