The Fox 2.0 Series Shaft Guard Pair (11.3 TLG) Kit, MPN 803-02-052-KIT, is a pair of roost shields for the exposed shock shafts on Fox 2.0 Performance and Evolution IFP shocks. Each guard deflects debris such as rocks and sand while still allowing air to circulate around the shock. The kit includes a pair of roost shields and all mounting hardware. Shaft damage is the main risk on a shock with a hard-chrome rod, and a nick there can compromise the seal. Owners on user forums say shaft damage can be mitigated by adding roost shields or a universal boot. A guard costs far less than a seal rebuild or a replacement shock, which makes it a practical upgrade for rock-crawling, desert running, or any high-speed trail use.
Fitment is the first thing to confirm. The kit is designed for eyelet-mount 2.0 Performance Series IFP and 2.0 Evolution Series IFP shocks, and it is not intended for shocks with stem-type bushings. Search terms that fit this item include "Fox 2.0 roost shield kit," "2.0 Performance IFP shaft guard," "rear shock shaft protector," and "803-02-052-KIT." Some tuners on user forums prefer a barrel-up, shaft-down orientation on their trucks. Owners on user forums note the roost guards only mount one way. Installation is straightforward on most lifted trucks, and the guards require no changes to the shock or the mounting points.
The kit is described for 2.0 Performance Series IFP and 2.0 Evolution Series IFP shocks with eyelet mounts, and it is not intended for stem-bushing shocks. Published fitment information varies between sources, so confirm your exact shock model with the manufacturer before ordering.
Owners on user forums report that the guards mount in only one orientation, so the shield should sit where the design intends. Some owners install the shock with the shaft down, which is the setup the guards were made to protect.
Owners on user forums say shaft guards help by deflecting debris, but they do not eliminate the risk. One tuner notes that a hardened steel shaft is harder to nick than a shock body, yet a nick can still cause seal failure.
Owners on user forums note the guards mount to the shock body in one direction only, so check orientation before tightening anything. Threading the mounting screws can be fiddly on a shock that is already installed, so starting the hardware off the vehicle is a common approach. Confirm the manufacturer's torque specs and tool list before starting, since none were confirmed during research.
