Fox has updated their 2020 Fit4-equipped forks to now feature an 8mm damper shaft, new bladder construction and a reconfigured shim stack. The 8mm damper shaft has a smaller cross-sectional area, theoretically pushing less oil through the base valve, allowing for less damping. The updated Fit4 damper should provide more sensitivity while also maintaining low-speed compression support during aggressive riding, giving riders the ability to tune their fork to feel playful, aggressive, playfully aggressive, aggressively playful….you get the gist.

The rebound side implements Fox‘s latest tuning improvements through a wider opening check valve and a reconfigured shim stack. The new Fit4 damper assembly construction is lighter as well, with an average weight savings of 35 grams.

The 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 22 clicks of low-speed compression adjust in the Open mode, allowing riders to fine-tune their exact damping preferences.

Also new for 2020 is an 8mm x 30mm roller bearing rear shock mounting kit. Deploying outboard-mounted full complement roller bearings — as opposed to standard bushings — allowing the shock to move more freely as the frame cycles through its travel. Roller bearings reduce friction and improve performance to such a degree that in some cases more rebound damping and/or low-speed compression damping may be needed in order to compensate for the decrease in friction.

The roller bearing shock mounting kit is compatible with all current Fox rear shock models and it is also compatible with many popular brands such as Santa Cruz, Transition, and many others.

This new mounting kit requires a special tool, so stop by your local bike shop to purchase these sick upgrades and make sure you either have the right tools for the job or have a professional helping you up with their expertise if needed.
