Description

Dial in the angle, dial in the feel

The North Sonar Stabilizer Shim Kit lets you precisely tune your foil’s sweet spot. By changing the stabilizer shim (angle of attack, AOA) you control rear lift—and with it front-foot pressure, stability, pump cadence and carve radius—without moving your stance.

What shimming changes

Adding a positive shim increases the stabilizer AOA: more rear lift, higher front-foot pressure, extra stability and hold in gusts. A negative shim reduces front-foot pressure for a freer feel, quicker pump and snappier transitions.

Quick adjustments, wide range

The kit is stackable, covering a wide range from the factory baseline: -0.5° to +2.5°. Make micro-adjustments in seconds—without fully removing the stabilizer—to match conditions, front wing or discipline (freeride, surf/wing, downwind).

Technical features

• Stackable shim range: -0.5° to +2.5°
• Fast tuning without taking the stabilizer off
• Dialed for multiple disciplines and front wings
• Cost-effective way to upgrade foil behavior

In summary

With the Sonar Stabilizer Shim Kit you precisely manage pressure balance and foil character: more comfort, less fatigue and line-perfect carves in any water state. You’re in control.
