The RockShox 11.4015.380.040 is a genuine RockShox service component, designed to keep your suspension performing at its best. Using original RockShox parts helps maintain the precise feel, reliability, and safety that your fork or shock was engineered to deliver. Over time, seals, o-rings, and internal wear items naturally degrade, allowing dirt and moisture to enter and oil to escape. Refreshing these parts with the correct RockShox kit restores smooth action, consistent damping, and proper lubrication, so your suspension can respond quickly and predictably on every ride.
This RockShox service item is ideal for riders who want to extend the life of their suspension and avoid costly premature replacements. Whether you ride aggressive trail, enduro, or simply enjoy regular off-road adventures, periodic servicing with the right kit helps prevent stiction, reduces unwanted play, and improves small-bump sensitivity. Pair this part with quality suspension oil and follow RockShox’s recommended service intervals for the best results. It’s a smart upgrade for any rider who values performance, control, and long-term durability from their RockShox suspension.
