ION 4 — The Evolution of a Proven Champion

Building on one of the most successful slalom skis ever produced, the new ION 4 takes the winning ION platform to the next level.

The ION III dominated tournaments worldwide — winning major events and completing more 41off / 10.25 m passes than any other ski on the market. The ION 4 retains the exact proven shape and geometry as the ION III but introduces an advanced new carbon layup that delivers a noticeably more responsive ride without sacrificing the consistency and predictability that made the ION series legendary.

If you loved the confidence of ION III, the ION 4 will feel instantly familiar — only quicker, livelier, and more connected.

Faster Response. Same Proven Platform – The ION 4 maintains the speed needed for powerful outbound cast off the wakes and into each turn — with the same signature symmetry on both onside and offside turns. The difference is in how quickly the ski reacts beneath your feet.

The refined carbon construction enhances feedback and energy return, allowing the ski to:

• Initiate turns more instantly
• Build angle sooner
• Accelerate with greater efficiency
• Maintain stability under heavy load

The result is a ski that stays ahead of the boat more easily, especially on the toughest passes.

Confidence From the First Pass. Like its predecessor, the ION 4 features a large, sweet spot underfoot that you will feel immediately as you glide for the gates. The ski settles into the groove early, providing a stable platform that lets you commit fully to each turn.

As you approach the buoy, the ski naturally begins its rotation sooner and more decisively, establishing maximum angle before loading the line. With the enhanced responsiveness of the new layup, that rotation happens with less effort and more precision.

Symmetrical Turns — Onside and Offside. D3 skis are renowned for exceptional offside performance, and the ION 4 continues that legacy. The ski delivers powerful, clean offside turns while dynamically building angle on the onside, keeping both sides of the course equally strong and predictable.

Balanced Speed, Control, and Predictability. The ION 4 preserves the hallmark cross-course speed, consistency, and smooth ride of earlier ION models. The front section provides balance and control as you accelerate off the wake into the pre-turn, while the tail tracks cleanly to maintain stability throughout the turn.

Ideal for skiers who:

✔ Ride balanced over both feet

✔ Have a technical, rhythm-focused style

✔ Prefer carving turns on both sides

✔ Demand top-tier tournament performance

The overall feel is intuitive and forgiving — yet capable of elite-level performance.

Hand-Crafted Performance. Every D3 ski is beautifully hand-built in the USA by skilled craftsmen with uncompromising attention to detail. The new layup represents the latest evolution of D3’s materials and manufacturing expertise, delivering unmatched consistency and quality.

Technical Highlights:

• Ski Profile — Traditional Shape – Best ridden in a balanced stance over the center of the ski.
• Tunnel Concave — Promotes excellent cross-course speed and efficient glide.
• Rocker Profile — Multiple Stage – Optimizes the sweet spot, balance, and rotation into and out of the turn.
• Tail Geometry — Provides support and drive while maintaining control.
• Bevel Shape — The larger soft tail bevels allow the back of the ski to move smoothly through the turn in harmony with the tip.
• Accuset Fin Block — Precision three-point adjustment with laser-aligned positioning.
• Machined Screw Inserts — Compatible with D3, Reflex, and most modern binding patterns for secure mounting.
• Sizes — 64″, 65″, 66″, 67″ & 68″
