FOX 38 GRIP X2 Damper Details
GRIP X2 Adjustments:
High Speed Compression: 8 clicks
Low Speed Compression: 18 clicks
High Speed Rebound: 8 clicks
Low Speed Rebound: 16 clicks
New for 2025 FOX’s longer travel and more aggressive forks have been fit with the new GRIP X2 damper.
The GRIP X2 replaces the previous GRIP2 damper on the top tier Factory Kashima FOX 38 forks. The GRIP X2 damper is designed with mechanical differences giving it an on trail performance advantage to the previous GRIP2 dampers.
What are some of the notable updates?
Bigger is Better. Well, with Base Valves!
On the GRIP2 damper the base valve measured 20mm. With the revised GRIP X2 FOX increased the base valve to 24mm.
FOX also took the GRIP2’s 7 valve stack and increased it on the GRIP X2 to a 23 count valve stack. This improves the overall tune capacity with the goal of improving the fluid engagement through the damper.

Why Riders Choose BikeCo.com for Suspension
There are many reasons riders choose to purchase suspension from BikeCo.com. Two of the most notable are our proprietary BikeCo Pro Tune services available on FOX products as well as our unbeatable after-sales service and setup availability.
FOX forks and shocks have distinguished themselves as class leaders across all MTB disciplines. With a wide range of dampers, adjustments, travel options as well as chassis riders have options to dial in their bike. But, working with BikeCo.com you’ll get more out of your new fork or shock and it’s something the competition simply can’t offer: Access to our team’s combined expertise on setup and tuning.
Modern suspension offers a range of adjustments. PSI, Volume Spacing, Compression – possibly High and Low Speed as well as Rebound – again possibly high and low speed.
While many manufacturers offer basic setup points the magic is being able to fine tune the fork or shock to accommodate your riding specifics. Working with the team at BikeCo.com riders are able to more quickly dial in a setup as well as understand where their setup is likely to advance as riding speeds and confidence increase.
Clients purchasing Suspension products from BikeCo.com will take delivery with a personalized setup sheet with suggestions for a starting point (as well as somewhere to come back to if you decide to spin all the knobs during your setup pedal in front of the house!).
Our team will then reach out at intervals with questions to help us understand how the fork or shock works for your individual riding. These intervals are designed to allow you a couple rides to quantify your impressions and then readdress minor changes to the setup. Of course, our team is available at any point in between if you have questions on your suspension.
Since 1999 BikeCo’s suspension experts have worked with a wide range of riders. From World Cup Level Pros to brand new riders. With this experience we are unmatched at setting up bikes performance, so the rider isn’t fighting the tune but simply concentrating on riding the trail.
Our team works together with our suspension tuners and BikeCo owner Joe Binatena to ensure clients get the best setup and tune concepts in the industry.
We will help you define how one adjustment may effect another setting as well as help you understand how your suspension is interacting with other components. Don’t get lost spinning dials when you can work with the best and have a thorough understanding, or simply someone to tell you which dials to turn if you’re that rider!
PSI, Ramp Rate, High and Low Speed Compression, High and Low Speed Rebound, Cockpit Setup, Brake Setup, Tire Pressures and Sidewalls, Riding Positions, Terrain – a lot of things going into really dialing in how your bike feels through the chunk, into corners and under power.
With experts working in your corner why would you shop MTB or eMTB Suspension anywhere but BikeCo.com?
