The FOX 883-09-153 is a 3.0 Factory Series shock built on the brand's 3.0 platform. The manufacturer says the internals of its 3.0 race-derived shocks carry over from its Trophy Truck program, including stainless steel shock shafts, PTFE-lined spherical bearings, proprietary racing oil and high-temp Viton seals. Owners searching for race-bred damping without a full custom build get that hardware in a bolt-on unit.
Why choose this over stock or a cheaper aftermarket shock? The external piggyback reservoir moves the oil away from the shock body, which helps with heat control during sustained off-road running. The manufacturer's Raptor 3.0 pages describe large remote reservoirs with a large -10 hose that increase cooling capability. The design also maximizes the entire wheel travel and increases oil capacity, which matters on rough terrain where a stock shock runs out of control. Spring preload and ride height can be adjusted, and the integrated coil spring comes pre-set to level your vehicle right out of the box.
The manufacturer says its remote reservoir design, paired with a large hose, increases the shock's cooling capability on its 3.0 Factory Race Series Raptor shocks. Confirm the reservoir specifics for this exact part number with the manufacturer.
Per the manufacturer, the integrated coil spring can be adjusted for preload and ride height, and it is pre-set to level the vehicle from the factory.
The manufacturer states these shocks are designed to bolt onto the factory mounts, so the job is a direct replacement rather than a custom bracket install. Before starting, check torque values and reservoir mounting and hose routing in the manufacturer's install sheet, which was not located for this part. Confirm your vehicle's model year fitment with the manufacturer before ordering.
