Full Access UTV Nitrogen 2.5" Shock Reservoir Caps set of 4

One of the simplest upgrades you can make that actually improves how your machine rides.

The Full Access UTV 2.5" Shock Reservoir Caps are designed to fix a common issue with factory Fox shocks—nitrogen loss. When pressure drops, ride quality suffers, shocks fade faster, and performance falls off quick. These billet caps replace the weak factory setup with a more durable, serviceable solution.

Built to protect the valve and maintain proper pressure, they help keep your suspension working the way it should.
