Performance Engineered: Full 4-Way Adjustability
Precision-tuned for the serious rider. Diamond+ Shocks are designed to be fully customizable to your vehicle’s weight, your riding style, and the terrain. No more “one-size-fits-all” suspension.

- 🌀 Adjustable Preload: Dial in your sag using the included tool to tighten the collar above the spring coils.
- 📉 Compression Tuning: Control how fast the shock compresses. Use the included Allen wrench to adjust the inside silver knob located on the top reservoir.
- 📈 Rebound Tuning: Manage the shock’s return speed. Use the included Allen wrench to adjust the inside silver knob located on the bottom reservoir.
