Finding Your Perfect Fit: A Guide to Billetworkz Shift Knob Shapes
Face it, Stock SUCKS
When you think about mods that change the way your car feels, most people jump straight to exhausts, coilovers, or a tune. But ask any seasoned enthusiast, and they’ll tell you: some of the most overlooked mods, like a Weighted Shift Knob can transform every drive. It’s the one part you touch every single time you row through the gears, whether you’re chasing apexes on a track day or just merging onto I-95 with your coffee in the cupholder (no judgment if you stall once in a while).
First things first - all cars are different in terms of mounting and features like a reverse lockout and a boot retainer. That’s why choosing the right fitment for your vehicle is just as important as picking the shape you love. We want to ensure that the perfect shape is paired with the correct fitment, so you get the best look and feel every time you drive.
Round Knobs: The Classic All-Rounder
If shift knobs had a Mount Rushmore, the round ball would be front and center. It’s timeless, ergonomic, and universally loved. The round design lets your palm wrap comfortably, no matter how you grab it — great for spirited driving or just cruising.
As close to a typical OEM fit as you can get (but with the added Billetworkz sauce and weight) translates to smoother, more controlled shifts. Round knobs are the “daily driver hero”: simple, effective, and always stylish. Think of it like the Chuck Taylor of shift knobs — never goes out of style.

The Lightbulb |

Smooth in the hand and precise shifts, no matter how you grab it. Perfect for daily driving if you want comfort and timeless style without overthinking it. Low-sitting and great for vehicles that have a standard-sized reverse lockout. Weight: 450g | Diameter: 2" | Height: 2" |
Slightly higher to allow more of an overhand grip while still maintaining comfort and smoothness with every shift. Great for vehicles that don’t have a reverse lockout. Weight: 500g | Diameter: 2" | Height: 2.375" |
“Excellent quality and craftsmanship. Best quality Knob I’ve owned thus far. Heavy-duty build and added weight make driving amazing. Definitely enhances the shifting experience.”
— Michael Antoun, 2015+ Mustang
Teardrop Knobs: For Smooth Shifts
Want to feel like a race car driver every time you heel-toe into second? The Teardrop is your shape. Tapered at the base and fuller at the top, this knob naturally guides your hand into a precise, confident grip.
From track days and autocross runs to home on backroads when you want to feel dialed in—one of our most popular options, especially for those vehicles that have oversized reverse lockouts.
Offered in both Short & Tall Teardrop, you can’t go wrong with either, as both feel equally comfortable.

The Short Teardrop |
The Tall Teardrop |
|
The Short Teardrop typically provides an OEM-style fit with large factory reverse lockouts. The added weight makes shifting smooth and precise. Weight: 450g | Diameter: 2" | Height: 2.25" |
For those who want a bit taller shift feel, the Tall Teardrop adds more height and weight; also allowing a comfortable side grip. This is the perfect option if you want a classic round shape but with added leverage. Weight: 450g | Diameter: 2" | Height: 2.25" |
Piston & Sledge Knobs: The Statement Piece
Piston-style knobs give extra leverage thanks to their height, making long throws feel crisp and deliberate. If you’re the kind of driver who likes people to notice your cockpit setup, this shape delivers. It’s less “blend in at Cars & Coffee,” more “parked up front with the hood popped.”

The Sledge |
|
Tall, straight, and mechanical. These give extra leverage, making shifts feel more aggressive. They stand out visually too — a bold, motorsport-inspired look that feels like yanking a race car lever. Weight: 275g| Diameter: 1.5" | Height: 3" |
Absolute Unit. The Chonk. Beefcake. The Sledge is by far our heaviest knob, allowing for super buttery shifts. For those who want some meat to grab rowing through every gear, this is for you.. (Get your head out of the gutter) Weight: 1000g | Diameter: 2.25" | Height: 2.5" |
The Crème de la crème:
The Hybrid & The Fusion
The Hybrid
Hybrids are the synergy of quality materials to serve two main purposes: enhancing your shifting experience with it’s weighted, stainless steel core and temperature-resistant delrin shell (in black or white), to insulate and protect your hand from extreme heat and cold climates. Hybrids also come with Red, Blue, and Purple Cosmic aluminum styling options, but you trade out temperature resistance for a bit more color and style.
Weight: 245g (Delrin), 330g (Cosmic) | Diameter: 1.6" | Height: 3.5"
The Fusion
The Fusion takes everything people love and dials it up with premium materials. Its rounded shape feels natural in your hand, giving you a comfortable grip no matter how you drive. But the real magic is in the customizable center cores — choose Alcantara or Leather for that perfect mix of style and feel. Add in the precision of a weighted design, and you’ve got the “Swiss Army knife” of our lineup: versatile, balanced, and ready to elevate nearly any vehicle. The best part? Dozens of colors and engraving options to personalize your exact style.
Weight: 500g | Diameter: 2" | Height: 2.375"
Honorable Mention: Pickle Rick
Not for sale (seriously), but too legendary not to mention. Our one-off, 3D-printed Pickle Rick knob is the definition of overkill — massive, green, and guaranteed to make every shift feel like an interdimensional adventure. Zero ergonomics, 100% conversation starter. If you ever see it in a car, just know: that driver is committed to the bit.
