What Are Harrows Supergrip Stems?
Harrows Supergrip stems (also known as shafts) are premium dart stems designed to securely hold flights and maintain consistent flight paths. Made by Harrows, one of the most iconic names in the darts world, these stems are known for their:
- Reinforced construction
- Secure grip on dart flights
- Sleek, lightweight design
- Compatibility with a wide range of darts
- Stylish colours and finishes
They're available in various lengths and colours, making them perfect for players who want to fine-tune their dart setup or inject personality into their gear.
Why Supergrip?
The "Supergrip" name isn’t just for show. These stems are designed with a revolutionary flight locking system that ensures flights remain securely attached during gameplay—eliminating mid-throw detachment or loosening, which can seriously impact a game’s outcome.
Kiwis love gear that’s tough, no-nonsense, and designed to perform—and Supergrip stems deliver that in spades. Whether you’re throwing darts after work in Rotorua or competing in a tournament in Dunedin, Supergrip stems keep your flights locked in and your focus on the target.
Key Benefits of Harrows Supergrip Stems
🎯 1. Secure Flight Hold
One of the biggest annoyances in darts is flights popping out mid-game. Supergrip stems come with built-in rings or grip enhancements that hold flights firmly in place, giving you one less thing to worry about during gameplay.
🎯 2. Reduced Dart Wobble
Flight stability is crucial for consistent, accurate throws. With their engineered grip and precision fit, Supergrip stems help reduce movement in-flight, offering tighter grouping and better results.
🎯 3. Durable and Long-Lasting
Harrows uses advanced materials that resist cracking and wear—even after heavy use. This means fewer replacements and better long-term performance.
🎯 4. Lightweight Construction
Maintaining optimal dart balance is key. Supergrip stems are built to be lightweight, ensuring they don’t throw off the weight distribution of your darts. You’ll enjoy smooth throws and predictable flight patterns every time.
🎯 5. Range of Sizes and Colours
Choose from short, midi, or medium lengths to suit your throw style. Want a sleek black look? A transparent finish? Or maybe bold colours to match your flights? Supergrip stems come in a variety of colours to complement your setup.

Tips for Getting the Most Out of Your Supergrip Stems
-
Match the stem length to your playing style: short stems offer tighter grouping; longer stems can give you more control and stability.
- Use quality flights—Supergrip stems enhance performance, but they shine when paired with quality flights.
- Regularly check for wear and tear. While durable, no shaft lasts forever—replacing worn stems keeps your throws sharp.
- Clean occasionally. Dust or oil buildup can affect flight grip.
