XRAY X4 Rear Body Post Holder Set Hole Width 112mm by Factory Pro O-XCP012  [FP-O-XCP012]

Rear body post holder for X4

This is an RC-scale accessory intended to replace or upgrade the rear body post mounting on XRAY X4 chassis where the body post hole spacing is 112mm. The Factory Pro O-XCP012 set focuses on providing a stable mounting point for the rear of the polycarbonate body to reduce movement during cornering and high-speed runs.

Compatibility is limited to XRAY X4 configurations that use a 112mm hole width for rear body posts. The part functions as a holder for standard body posts and works alongside existing chassis mounting points and body clips; it does not alter chassis geometry or suspension settings.

Installation is straightforward for hobbyists familiar with body post work: remove the body, fit the holder to the chassis mounting area aligned to the 112mm spacing, secure with the appropriate screws, then refit the body posts and check alignment. Use common hex drivers and avoid over-torquing fasteners to prevent deforming the holder or the chassis mounting points.

From a tuning perspective the holder helps maintain consistent body position across practice and race runs, which can make aerodynamic behavior and weight distribution more repeatable during setup changes. It is a practical part for those refining body fitment or switching between body shells while keeping rear mounting alignment consistent.
