I've always enjoyed a happy ending.

It's a gorgeous shift knob. Out of all the money I've spent on my vehicle, I feel this shift knob is like the crown jewel. It feels great in my hand and it makes the shifting so much better.

Made shifting so much smoother! My car doesn't have a short throw option but this shift knob bridged the gap decently

Love this weighted shift knob

I felt an immediate difference from the stock shifter in my NA8 Miata. The shifting is incredibly smooth, it drops right into gear AND it looks great!

Happy Endings, you have got some balls my friend…

Weighted Shifter balls to be exact. Love the engraving, super clean! Came pre-attached to the cvt adapter from Billetworkz and shipped quick as hell. Overall, I couldn’t be happier!

If I could give it more than 5 stars I would! Thank you for all the support :)

Super responsive and passionate team pushing super unique high quality products. Had a question and heard back in under 2 hours. Got the black glitter weighted shift knob and it is hands down the best feeling and best looking shift knob I have ever owned. The weight feels incredible, I can practically just flick the shifter and the knob carries it into gear, and that rainbow sparkle is so beautiful I have no choice but to wrap the interior trim in a matching vinyl. Keep killing it Happy Endings team 🤘🏻
