Fox 2.0 Reservoir Rebuild Service

To Service or Not to Service?

Rebuilding the Fox 2.0 Reservoir shock is a no-brainer in terms of cost benefit. When you can get your shocks serviced for about $100-125 each, this far outweighs the cost of purchasing a brand new set ($1000-1200).

When people purchase brand new Fox shocks, they often ask us “how often do I need to service these shocks?” There’s no universal answer; brands like Fox and Icon recommend servicing at least every 50k miles, but that mileage varies depending on driver behavior.

Going hard every weekend - 50k miles may be far too late.
Daily driver with occasional easy dirt terrain - 40-50k miles is safe.
Desert buggy that sees 1,000 miles over the season - probably needs a rebuild once a year.

How to Determine When Your Shocks Need Service

So there’s no universal answer as to when you should service these parts, it comes down to how much abuse they’ve seen. But then you may ask “how can I tell if my shocks need service?”

Things feeling more squishy than usual? More body roll? Hitting your bumpstops more often? Those are telltale signs of shocks not operating at 100%.

You can do a nitrogen gas pressure test at an off-road shop to see what the PSI is currently, vs what they were when freshly built.

You can clean the shock completely before a weekend, and on Sunday after the fun was had, see if there’s oil or fluid on the shock. This is a sign there are leaking seals.

When we refresh shocks like these, new seals go onto the seal head, new wiper seals are installed, and other internal O-rings get replaced. New oil is put in, and that oil quality varies depending if you want top of the line race oil, or a more standard type of oil with less friction (than race oil).
