Rockeater Tune for Fox 40 FIT4 forks & dampers 2016-17 that have low speed compression adjusters
Incorporates Vorsprung Fractive hardware

This is a preconfigured set of modifications and internal tuning which is targeted at 70-80 kg riders who like to ride rough stuff fast without getting beaten
They have enough range to also work great for riders from 60-90 kg
But even outside those limits they're better than anything you'll find factory

The Rockeater Tunes are based on our Matrix & Custom Tune series.  But it's simpler.  There are no calculations or data needed.  Just send us either your fork or damper.  We will service, install and dyno test to make sure it's running perfectly.

As the Rockeater Tunes are a one-size-fits-all upgrade, they provide the same performance and improvements for any future owners, preserving your investment.
