Fox Racing Shox 38 Factory 29" GRIP-X2 - 44mm Offset - 2025

New GRIPX2 Damper
To create the ultimate descent-focused damper, we sought the level of tunability seen in motocross and supercross racing suspension. Our award-winning Grip 2 damper had a 20 mm base valve diameter and seven valves. Grip X2 scaled up the tunability by increasing the base valve diameter to 24 mm with 23 valves. The result is the most tunable, supportive, and smoothest descent-focused fork damper ever created by FOX. Riders reap the benefits of sitting higher in the travel while tires stay glued to the ground. They can corner with increased traction, giving them the confidence to push the limits of downhill and enduro racing, all while reducing overall rider fatigue.

  • 23 Count Valve Stack for unprecedented tunability and quicker response to bumps.
  • Award-winning Grip 2 damper had a 20mm base valve diameter and seven valves. Grip X2 scaled up the tunability by increasing the base valve diameter to 24mm with 23 valves.
  • 24mm Base Valve lowers pressure to increase sensitivity and allows space for more damping circuitry.
  • Pressure Balancing maintains low positive pressure, allowing 5-10ms damper response time to rider inputs.
  • 4-Way Adjustability with high/low-speed compression and high/low-speed  rebound, now with less cross talk.

The Genuine Kashima Coat upper tube finish is slippery smooth and ultra-durable.

Floating Axle
The 38 comes equipped with a new quick-release, lever operated, patent-pending floating axle system that combines the benefit of a floating axle with the ease of a tool-free quick-release. With this system, spacing is locked in via a floating sleeve, allowing repeated front wheel removal and re-installation while maintaining perfect fork alignment. Floating sleeve positioning comes preset from the factory so if you are unsure of how to operate the floating axle system or simply don’t want to bother with it, you can just install the front wheel and get on with your ride.

Lower Leg Channels
As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Fox's lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping.

The lower leg bleeders allow for atmospheric pressure equalization at the simple press of a button. Pressure build-up in the lower legs dramatically decreases fork performance, preventing full travel from being achieved, and diminishing small bump sensitivity and responsiveness.

Lower Leg Arch
Modern frame designs and geometry trends require modern suspension design solutions. The arch design of the all-new 38 is designed to pair perfectly with modern Enduro bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. The new arch shape takes this need into account by jutting forward to provide ample headtube clearance at full compression. State-of-the-art computer modeling techniques helped Fox create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material.

Elliptical Steerer
The 38’s elliptical steer tube is one of many ways Fox further optimized stiffness-to-weight, placing more material only where it is needed, and eliminating every ounce of it where it’s not.


  • 31% stiffer transverse shear, 17% stiffer fore/aft and 38% torsionally stiffer than 36
  • Optional mud guard
