1. Fox 40 Setup Guide

Setting Sag for the Perfect Ride

The Fox 40 is a dual-crown downhill fork designed for big hits and fast descents. Setting sag correctly ensures optimal performance.

  1. Step 1: Wear full riding gear and get into your downhill attack position.

  2. Step 2: Have a friend check the sag or use a sag meter.

  3. Step 3: Adjust air pressure or coil preload accordingly:

    • 15-20% sag for aggressive downhill riding.

    • 20-25% sag for a slightly softer, more forgiving ride.

2. High-Speed vs. Low-Speed Compression Tuning

The Fox 40 features high-speed and low-speed compression adjustments, critical for optimizing big-hit absorption and stability.

High-Speed Compression (HSC): Controls the fork’s response to large impacts, like jumps and rock gardens.

  • Too soft? Bottoming out on big hits.

  • Too firm? Uncomfortable, harsh ride over rough terrain.

  • Pro Tip: Start mid-range and fine-tune based on terrain.

Low-Speed Compression (LSC): Affects how the fork responds to braking and slow-speed movements.

  • Too soft? The fork dives under braking.

  • Too firm? Reduces sensitivity to small bumps.

  • Pro Tip: If your front end feels unstable in corners, slightly increase LSC.

3. Rebound Tuning – Keeping the Fork Under Control

Rebound controls how quickly the fork returns after compression.

Too Fast? The fork will feel bouncy and unstable. ✔ Too Slow? The fork will pack down and feel sluggish on consecutive hits.

🛠 Setup Tip:

  • Start in the middle of the rebound range.

  • Test on a rough descent and adjust based on feel.

Proper maintenance ensures your Fox 40 remains buttery smooth and responsive. Stick to this service schedule:

Every 100 Hours or 6 Months – Lower leg service (clean and re-lube wipers, refresh bath oil). ✔ Every 200 Hours or Annually – Full damper and air spring service. ✔ Heavy Use? Get a full rebuild at Suspension Werx.
