What the Fractive Upgrade Changes
Fractive is a compression-damper tuning system for selected Fox FIT4 forks. Vorsprung developed the system around a replacement compression piston and rider-selected compression valving to increase the useful tuning range and improve support without treating every rider as the same application.
Compression damper
Vorsprung Compression Piston
The Fractive system replaces the compatible FIT4 compression piston and uses a selected compression valve stack rather than changing the fork's air spring.
Control layout
Expanded Compression Adjustment
On supported Fractive configurations, the FIT4 three-position compression control is repurposed to provide a more useful high-speed compression range while retaining low-speed compression adjustment.
Tune selection
Rider-Specific Compression Valving
The compression tune is selected around the rider and application rather than installed as one generic setting for every compatible fork.
Fitment first
Fractive Compatibility
Fractive is specific to supported Fox FIT4 damper generations and is not a universal Fox fork upgrade. CJSUSPENSION checks the fork model, production year and exact damper before confirming fitment.
CJSUSPENSION continues to list and support Fractive kits for compatible FIT4 applications. Stock and exact compatibility are confirmed before booking installation.

Fractive Damper Service and Tune Support
CJSUSPENSION can service a supported Fractive-equipped FIT4 damper, inspect the installed tuning components and review the current setup when rider, bike or terrain requirements change.
FIT4 Damper Service

Compression Tune Review
Rider feedback and the current control range are reviewed before supported changes to the compression tune or baseline settings are made.

Vorsprung Fractive FAQs
Can CJSUSPENSION supply and install Vorsprung Fractive?
Yes, where the required CJSUSPENSION stock and supported Fox FIT4 application are confirmed. Exact fork and damper identification is required before the kit is allocated.
Can Fractive be fitted to every Fox fork?
No. Fractive is specific to supported Fox FIT4 damper generations. The exact fork, production year and damper configuration must be checked first.
Is damper servicing part of Fractive installation?
Yes. CJSUSPENSION installs the supported Fractive components as part of a correctly prepared and serviced damper so the tune is not added to a contaminated or mechanically compromised cartridge.
