Fractive is Vorsprung Suspension's own tuning system for the Fox FIT4, factory series, damper. The FIT4 damper is a three position adjustable damper. The factory series (F-S) version has a second dial in the centre for low speed compression (LSC) damping adjustment.
Note Fractive isn't compatible with the performance series (P-S) or earlier CTD-FIT dampers and is not compatible with remote equipped dampers or the RC versions with HSC/LSC compression dials.
This tuning system replaces the internal valving in the damper and comes fitted with one of 5 preset tunes, tunes which you can select using the Vorsprung YouTune calculator here.
Once your damper has been upgraded to Fractive the centre dial remains as low speed compression (LSC) and the outer dial (formerly Climb-Trail-Descend) becomes a high speed compression adjuster.
Shockcraft can supply Fractive tuning fully installed in your fork during service, installed in your damper if you just want to send that or as a kit for DIY installation.

A Shim Shuffle is changing the stock tune in a fork or shock damper to another factory pre-configured tune. For example changing a medium tune to a firm tune or a soft tune.
It is only available with a fork or shock service where factory tunes are published. It does not include any shims or parts, they are charged separately if required.
This charge is for shim shuffle as part of any compatible fork or shock service.
