Product Details

The Honda OEM Shift Knob Lock Nut is a genuine factory replacement designed to secure and properly position the manual transmission shift knob on compatible Honda and Acura vehicles. Featuring an M10 x 1.5 thread pitch, this factory shift knob retaining nut allows the shift knob to be tightened securely while maintaining the correct orientation of the shift pattern.

Originally used on popular Honda performance models, including the Acura Integra Type R, Honda S2000, Honda Civic Si, and Acura TSX, this genuine Honda lock nut is an excellent replacement for missing, damaged, or worn factory shift knob hardware.

Installation Notes

Installing the Honda OEM Shift Knob Lock Nut is a straightforward process on compatible manual transmission vehicles.
Remove the existing shift knob from the threaded shift lever.
Inspect the shift lever threads for damage or debris.
Thread the Honda OEM lock nut onto the shift lever.
Install the shift knob onto the shift lever until it reaches the desired position.
Rotate the shift knob so the shift pattern is properly aligned and facing the driver.
Hold the shift knob in position and carefully tighten the lock nut against its base.
Verify that the shift knob is securely fastened and does not rotate during normal operation.
Important: Do not overtighten the lock nut, as excessive force can damage the shift knob, threaded shift lever, or surrounding components.
For aftermarket shift knobs, confirm that the knob provides sufficient threaded engagement and a suitable surface for the lock nut.
