Avery V. ★★★★★

Finally, no more ugly gap between the boot and knob—the threads are perfectly machined so it screws on tight and stays flush. Made my interior look a lot cleaner without any fuss.

Harper W. ★★★★★

Installed this on my 2003 Miata and it completely eliminated the gap around the shifter. The 10x1.25mm threading matched up perfectly with my aftermarket knob, and the finish looks like it came from the factory.

Henry J. ★★★★★

That gap between my boot and knob bugged me for months, and this retainer closed it right up. The finish looks factory, not like some bolt-on afterthought. Fits my 10x1.25 shifter snug with no wobble.
