The Fox 38 Performance Elite fork stands out as a top-tier choice for aggressive trail and enduro riders who demand both precision and durability. Built around a robust 38mm chassis, this model bridges the gap between the Factory series and the more budget-oriented Performance model. With its GRIP2 damper and high-end internals, the 38 Performance Elite provides pro-level performance without the golden Kashima coat, making it a compelling upgrade option for discerning riders.
Tools Required
- Torque wrench [paid link] with appropriate sockets
- Allen keys [paid link] (typically 4mm, 5mm, and 6mm)
- Suspension pump
- Ruler or calipers
- Shock oil and seal kit (for advanced maintenance)
- Clean rag and isopropyl alcohol
Installation Process
Installing the Fox 38 Performance Elite requires precision and careful alignment to ensure optimal performance and safety. Begin by removing the old fork, noting headset stack height and axle spacing. Trim the new steerer tube as needed, then install the star nut or insert the threaded steerer plug, depending on your headset setup.
Ensure the headset bearings are greased and seated correctly. Slide the fork into the head tube, add the necessary spacers, and torque the stem bolts to specification. Attach the brake caliper, ensuring it aligns without rubbing, and tighten the axle securely with the correct torque value. Finally, double-check the rotor clearance and cable routing to prevent interference during travel.
Adjustment Settings and Suspension Tuning
Tuning the Fox 38 Performance Elite begins with setting sag, typically around 15–20% of fork travel. Use the suspension pump to adjust air pressure according to rider weight. The GRIP2 damper offers both high- and low-speed compression and rebound adjustments.
Start with manufacturer-recommended settings based on rider weight and gradually fine-tune based on terrain and riding style. More low-speed compression increases support in berms and under braking, while adjusting high-speed compression controls big hit absorption. Rebound should be set to return quickly without bouncing.
Fine-tuning rebound and compression can drastically alter the fork’s character, so riders should document changes and test on familiar trails for reference.
Routine Maintenance and Service Intervals
Maintaining the Fox 38 Performance Elite ensures consistent performance and extends fork longevity. Wipe down stanchions and seals after each ride using a clean rag and isopropyl alcohol. Inspect the dust wipers for dirt and ensure no oil is leaking from the seals.
Every 50 hours of riding, perform a lower leg service. This involves removing the lowers, cleaning the internals, replacing bath oil, and checking foam rings. At 100–125 hour intervals, a full damper and air spring service is recommended, which includes oil changes and seal replacement.
These service intervals are essential, especially for riders pushing the fork in wet or dusty environments.
Troubleshooting Common Issues
A few setup challenges may arise during installation or early use. If the fork feels overly stiff, double-check air pressure and ensure volume spacers are not excessive. Harsh top-out or knock sounds often indicate insufficient rebound damping or loose internals.
If brake rotor rub occurs, ensure the axle is torqued evenly and the caliper is centered. Uneven fork travel or excessive noise under load may signal worn bushings or insufficient bath oil. GRIP2 damper inconsistency could stem from improper compression settings or contamination—prompting a damper service.
Always check torque settings and ensure no misalignment in the steerer or crown.
Performance Customization and Personalization
To maximize performance, riders can customize the Fox 38 Performance Elite through volume spacers, allowing for ramp-up tuning. Adding spacers increases progressiveness for aggressive descents, while removing them softens the mid-to-end stroke.
Additionally, personalized damper settings are vital. Many riders use a setup sheet or app to track adjustments across different trails. Upgrading to aftermarket SKF low-friction seals can reduce stiction, while swapping to a bolt-on mudguard helps preserve seal longevity.
Tuning fork offset and pairing it with slackened head angles or reduced stem lengths can also enhance cornering stability.
Comparing Fox 38 Performance Elite vs Factory and Performance Models
The Fox 38 lineup consists of Performance, Performance Elite, and Factory tiers. The Performance model uses a simpler GRIP damper, suited for less aggressive riders or budget-conscious upgrades. The Factory version offers the same GRIP2 damper as the Performance Elite but features a Kashima-coated stanchion for enhanced smoothness and longevity.
The 38 Performance Elite hits the sweet spot—retaining the high-performance internals of the Factory series without the premium coating, making it more affordable with nearly identical on-trail performance. Riders concerned with aesthetics and long-term durability may prefer the Factory version, but the Performance Elite delivers comparable ride quality.
Compatibility with Other Drivetrain and Suspension Components
The 38 Performance Elite is designed to integrate seamlessly with modern enduro and trail setups. It supports 110mm Boost spacing and comes in 160mm to 180mm travel configurations, compatible with both 27.5″ and 29″ wheels. Its tapered steerer tube fits standard headsets.
For drivetrain integration, ensure your frame’s geometry and headset angle accommodate the increased travel and fork axle-to-crown height. It pairs well with high-end rear shocks like the Fox Float X2 or DHX2 for riders looking to build a cohesive suspension platform.
Rotor compatibility supports 180mm to 230mm sizes using the appropriate adapters. The fork is also compatible with torque cap-equipped hubs, enhancing stiffness when paired with appropriate wheels.
Conclusion
The Fox 38 Performance Elite is a high-performing, race-ready fork engineered for serious riders. It delivers nearly all the benefits of the Factory version at a more accessible price point, making it a top contender for aggressive trail or enduro upgrades. With its precision tuning options, robust chassis, and serviceable design, it’s an investment that transforms the ride experience.
Frequently Asked Questions
Is the Fox 38 Performance Elite suitable for cross-country riding?
No. The 38 is overbuilt for XC and adds unnecessary weight. Riders should consider the Fox 32 or 34 series for lightweight performance.
Does the Performance Elite version include the GRIP2 damper?
Yes. The Performance Elite model features the high-performance GRIP2 damper with four-way adjustability.
Can I upgrade my Performance model to GRIP2?
Technically, yes—but it requires swapping out the entire damper assembly, which may be cost-prohibitive compared to purchasing the Performance Elite outright.
How does the ride feel compared to the Factory model?
Performance is nearly identical. The main difference lies in the stanchion coating, which marginally improves small-bump sensitivity and reduces wear over time.
What wheel sizes are compatible with the 38 Performance Elite?
It supports both 27.5″ and 29″ wheels, depending on the specific model variant. Be sure to verify axle-to-crown height and travel compatibility.
Is this fork suitable for e-bikes?
Yes. The 38’s robust chassis and damping platform are compatible with most modern e-MTBs, especially those used for aggressive trail or enduro applications.
