FOX Racing Shox Bike

Frequently Asked Questions

• How do I choose the right Fox fork or shock travel for my riding discipline?

  Pick travel to match your bike frame and intended discipline: XC and light trail typically use shorter travel (roughly 100–130mm range), while enduro and downhill demand 160–203mm to absorb big hits. For rear shocks, measure eye-to-eye and match the shock travel to your frame linkage and sag targets, then fine-tune with air pressure or coil spring rate for rider weight and style.
• What’s the difference between Fox dampers like GRIP2, FIT4, and GRIP X2?

  FIT4 is a simpler, three-position damper (open/medium/firm) aimed at trail and XC riders who want an on-the-fly climb/lockout option. GRIP2 and GRIP X2 provide more tunability with independent high- and low-speed compression plus rebound adjustments (compression ranges up to ~3–22 clicks and rebound adjustment commonly 8–16 clicks), delivering finer control for aggressive trail, enduro, and DH riding. GRIP X2/GRIP2-equipped Factory builds are usually the choice when you need maximum adjustability and damping consistency.
• How does the Fox 36 compare to the Fox 38, and which should I choose?

  The Fox 36 is a versatile trail-to-enduro fork that balances stiffness and weight for aggressive trail riding, while the Fox 38 uses larger stanchions and a beefier chassis tuned for harder enduro and big-hit descents. Choose the 36 if you want lighter, more agile handling on mixed terrain; opt for the 38 if you prioritize absolute stiffness and impact resistance for steep, rough, or bike-park laps.
• Which Fox rear shock (FLOAT SL, FLOAT DPS/X, FLOAT X2, DHX) is right for my bike?

  FLOAT SL is built for XC racing where minimal weight and quick response matter, while FLOAT DPS (and FLOAT X/DPS variants) suit trail and all-mountain riders who want a three-mode damper and efficient pedaling. FLOAT X2 is a high-performance, 4-way adjustable air shock for aggressive enduro/gravity riders who need independent HSC/LSC and rebound tuning, and DHX is Fox’s coil/air option aimed at downhill riders who prioritize durability and controlled small- and big-hit performance.
• How do volume spacers, EVOL air sleeves, and Kashima Coat affect ride feel and tuning?

  EVOL air sleeves increase negative spring volume for lower breakaway torque and better small-bump sensitivity, while adding or removing volume spacers alters spring progression to reduce or increase bottom-out resistance. Kashima Coat on Factory stanchions reduces friction and improves durability for a smoother initial stroke and longer-lasting performance. Use a shock pump to set sag, then adjust air pressure and volume spacers to tune mid-stroke support and end-stroke resistance for your weight and terrain.
