Alien Shift Knob — Mercurius
Free US shipping. Made to order and checked out securely through our Etsy shop, where you pick your options.
Give your shifter a passenger from another planet.
Meet MERCURIUS, the grinning alien. Huge toothy smile, deep wrinkles and big black eyes painted by hand. It glows in the dark after a little daylight or a UV flashlight, so at night it lights up your console. No batteries.
Choose Your Alien
Every knob is made to order, so you can pick any of the six:
- AZOTH: the classic, calm big-eyed visitor
- TRISMEGIS: three eyes, smirking, up to something
- MERCURIUS: the grinning one (shown in the real photos)
- CITRINUS: tongue out, pure fun
- SOLARIS: the big brain, mouth wide open
- PHOENIX: hands up, mid-cheer
Photos of the other five are previews of the design. They glow the same and get the same hand painted eyes.
Pick Your Glow
Choose the color too. Five glow colors, each made to order:
- GREEN: glows bright green (shown in the real photos)
- YELLOW: soft yellow by day, glows green
- PURPLE: purple by day, glows blue
- ORANGE: orange by day, glows yellow
- WHITE: white by day, glows soft green
Color photos are previews of each filament color.
Made For Your Car
Every knob is made with the exact thread for your car, so it screws straight onto your shifter. No glue, no universal adapters. Any make, any model, manual or automatic. Just tell me your year, make and model at checkout. If I'm not sure about your thread, I'll message you before I start.
Threads we make: M6x1.0, M8x1.25, M10x1.25, M10x1.5, M12x1.25, M12x1.5, 3/8"-24 and more.
Lines Up Straight
Screw the knob on until the face points where you want, then tighten the lock nut and it stays put. The nut is included.
