4" FRC Flywheel - Back in Stock and shipping 2/4/2026

Massively improve your FRC and FTC flywheel shooter’s consistency and range with SWYFT Steel Flywheels — simple, brutally effective inertia weights precision-cut from 6.2 mm (0.244 in) thick mild steel using fiber laser technology.

Designed and battle-proven by top teams, these flywheels add the rotational mass you need to turn inconsistent shots into unstoppable, long-range rockets.

Key Features

• Serious Inertia: Thick 6.2 mm mild steel dramatically increases moment of inertia for smoother spin-up and far better shot-to-shot consistency.
• Two Proven Sizes for FTC:
  • 72 mm diameter – perfect balance of weight and space
  • 96 mm diameter – maximum inertia when you need extreme range
• New 4" OD Variant for FRC Robots: 101.6 mm diameter flywheel specifically engineered for FRC, with a smooth, deburred finish for clean stacking and clamping.
• No Finish – Pure Performance: Raw steel construction (expect minor surface rust over time — intentional for maximum mass at minimum cost).

Specifications & Recommendations

FRC 4" Variant Notes:

• Ideal for clamping to 1/2" hex axles using the SWYFT 1/2" Hex High Strength Clamping Split Hub (sold separately).
• Smooth, deburred finish for clean stacking and clamping.
• Stack multiple flywheels and clamp them all at once for easy inertia tuning.

Drop these steel flywheels onto your shooter and instantly feel the difference: tighter shot grouping and longer range. Simple, affordable, and devastatingly effective — now with a dedicated FRC variant optimized for the 2026 game.
