Fox 38 Factory Grip X2 2025 Fork

All the revolutionary features of the brand-new 36 packaged in a super-stout chassis engineered specifically for modern hard-hitting, long travel enduro-style riding. The all-new 38 is hungry to devour all you can throw at it and ask for more.

When you need to go really big, reach for the 38. Optimized for 160-180mm of travel, the 38 redefines capability of a long travel single crown fork, setting a new benchmark for confidence, performance, and durability. Welcome to the big time.

Features

• Forks with a 68HT designation refers to the diameter of the head tube of the bike. Most standard bikes use a 58HT whereas most E-Bikes commonly use the 68HT.
• Steerer tube design incorporates elliptical shaping in taper zone, further maximizing stiffness to weight ratio.
• Lower leg bleeders.
• Air/oil channels.
• Unique design maximizes stiffness to weight and offers improved head tube clearance via radical NEW arch shape.
• 31% stiffer transverse shear, 9% stiffer fore/aft and 20% torsionally stiffer than 36.
• Updated EVOL air spring.
• 58mm crown diameter to match modern frame shape profiles.

Technology

Grip X2

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.

Kabolt X Axle

A lightweight bolt-on floating axle, the Kabolt X shaves grams while increasing torsional stiffness via a sleeveless, single-sided pinch bolt design. Chassis alignment reduces unwanted friction between the upper and lower fork legs, providing much smoother suspension movement throughout the entire range of travel. The 36 E-Optimized is also available in a convenient tool-free quick-release lever floating axle.

Lower Leg Bleeders & Bypass Channels

Bleeders allow atmospheric pressure equalization at the push of a button. Lower leg bypass channels increase volume to alleviate pressure ramping as the fork moves through its travel. Both result in better fork performance by increasing small bump sensitivity and responsiveness.

Lower Leg Arch

The lower leg design of the 36 E-Optimized shaves every possible gram while maximizing stiffness and strength requirements of enduro and aggressive all-mountain riding.

Riders reap the benefits of sitting higher in the travel while tyres 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.

• Grip X2 is the winning difference.
• 23 Count Valve Stack for unprecedented tunability and quicker response to bumps.
• 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 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.
