Darts accessories engineered to keep flights secure and improve consistency for regular play. For club players and keen amateurs seeking fewer lost flights and cleaner groupings, Harrows Dart Stems bring carbon-tipped durability in multiple lengths. Are these the upgrade that will suit a serious practice routine?

⚡ At a Glance
  • Aerodynamic Profile: Unique profile boosts aerodynamic flow and reduces turbulence around the shaft and flight entry point
  • Best for: Club players and league competitors who want secure flights and consistent grouping
  • Not ideal for: Players who prefer freely spinning tops, as the carbon top is attached and does not spin freely

Polycarbonate bodies with a carbon composite rotating top improve entry and durability. Pro Grip shaft shape and an included shaft ring keep flights seated tightly at the entry point.


Secure Flight Retention – thanks to Pro Grip and shaft ring

Shaped flight entry and a Pro Grip surface hold flights firmly, and every stem includes a shaft ring to increase friction between flight and shaft. Extensive testing of the shaft shape optimises how the flight sits in the entry point.

Players experience fewer mid-throw flight slips and steadier groupings over extended practice and match sessions.

Predictable Aerodynamics – with carbon composite rotating top and polycarbonate body

A unique profile smooths aerodynamic flow while a carbon composite top is bonded to the main body and only rotates when struck by incoming darts. The construction avoids free-spinning parts that can rattle or shift.

Expect more consistent flight paths and fewer deflections when darts land close together on the board.

Customisable Setup – thanks to three shaft sizes and universal threading

Available in Short (35mm), Midi (42mm) and Medium (49mm), each stem uses a thread designed to fit any brand of dart barrels. Size choice lets players alter balance and flight behaviour without changing barrels.

Select the shaft length that matches throwing style and barrel balance to improve comfort and control.

✨ The 4 Key Reasons for Harrows Dart Stems
  1. Pro Grip shaft profile – Keeps flights firmly seated, reducing mid-leg loosening during matches
  2. Carbon composite rotating top – Allows clean entry when darts cluster, lowering bounce-outs
  3. Shaft ring included – Creates a tighter fit between shaft and flight for improved stability
  4. Three size options – Match shaft length to throw for consistent balance and control

❓ Frequently Asked Questions

Q: Are these stems compatible with my existing dart barrels?

A: Yes. The thread is designed to fit any brand of dart barrels so they will screw onto most standard barrels.

Q: How many stems come in the pack?

A: Three sets are included, giving nine dart shafts in total.

Q: Do the carbon tops spin freely to reduce bounce-outs?

A: The carbon top is attached to the main body and does not spin freely; it will rotate only when incoming darts make contact, allowing a cleaner board entry.

🏆 Our Verdict

Perfect for club players and serious amateurs who value flight security and consistent aerodynamics. Polycarbonate bodies with a carbon composite top, Pro Grip entry and shaft rings set these stems apart for durability and stable performance. While likely a step up from basic disposable stems, long-lasting materials and universal fit make them a sensible long-term investment.
