The Factory Pro O-XCP005 downstop holder is offered as an upgrade or replacement compatible with O-XCP004 for XRAY X4 cars. It secures the body rideheight downstop so that heights can be reproduced after the shell has been removed and refitted.
The unit is designed to attach at the same points used by O-XCP004 and serves as a clear stop for body posts or mounts. In a setup routine it acts as a handy reference when changing shells, adjusting settings, or returning to a known rideheight during testing.
Fitment advice: verify the O-XCP004 mounting points on your X4 chassis, keep any original screws that fit, and check the body shell for interference before you tighten everything. Remember that fine tuning is done with shims or by altering body post position; this holder simply provides repeatable positioning.
