Fox Racing Shox - Technologies

Fox Racing Shox suspension systems are a technological wonder. Below you will find a handful of Fox's technologies explained so you can see for yourself.

32 SC Chassis-Design

DPS Dual-Piston-System
Fox's highest performing inline shock gets refined. Updated valve design improves both rebound and compression flow, allowing for active and supple Open and Medium modes without compromising Firm mode stiffness.

EVOL (Extra Volume)
A more linear spring curve gives EVOL forks and shocks plushness off the top, extra mid-stroke support, and more tunable bottom-out progression, allowing riders to tap into the ideal pairing of front and rear-end feel.

FIT4 - Fox Isolated Technology
New damper tune is found in all 34 and 36 FIT4 forks. A reconfigured shim stack provides more sensitivity while maintaining support when needed during aggressive riding.

In its fourth generation, the patented FIT4 closed cartridge system provides three on-the-fly compression damping positions—Open, Medium, and Firm—to adapt to varying trail conditions. Factory Series forks feature an additional 22 clicks of low-speed compression adjust in the Open mode, allowing riders to fine-tune their exact damping preferences.

GRIP
Inspired from moto, the new GRIP damper uses our FIT sealed cartridge technology combined with a coil-sprung, independent floating piston. GRIP allows excess oil to purge through specially designed ports at the top of the damper to maintain consistent damping and increase durability. Performance Series forks provide Open, Medium, and Firm modes with additional micro-adjust between settings.

Kabolt Axle
Inspired by Geoff Kabush through Fox's RAD program, the Kabolt is now available for all 15QR forks.

Kashima Coat
Kashima's distinctive gold color is backed by its high performance attributes—properties that provide an exceptionally smooth feel and extreme durability.

SLS Spring
A proprietary surface treatment and stress relief process removes residual stresses from the spring, allowing them to withstand higher stresses. Each spring is optimized by using a smaller wire diameter and less coils, creating a lighter spring.

X2
Fueled by two years of RAD development, X2 hits the sweet spot with its improved linear damping profile, revised oil flow, and redesigned seals on DHX2 and FLOAT X2 shocks. The wide adjustment range gives riders the support and grip that the trail demands, as well as a more plush and open feel in the initial travel.
