XRAY X4 Rear Shell Mount Upgrade 112mm Aluminium - Factory Pro O-XCP012  [FP-O-XCP012]

Rear shell post holder for X4

This accessory upgrades the rear body post mounting on XRAY X4 chassis layouts that have a 112mm hole width. The Factory Pro O-XCP012 set helps secure the polycarbonate body at the rear to limit movement during aggressive cornering and high-speed runs.

It is only compatible with XRAY X4 variants using a 112mm rear post gap. The component serves as a stable holder for standard body posts and integrates with existing chassis fixing points and body clips without changing suspension geometry.

Installation is straightforward for those familiar with body post tasks: strip the body, align the holder to the 112mm centres, tighten with the correct screws, then reinstall posts and confirm fit. Use routine hex tools and avoid over-torquing to protect the holder and chassis bosses.

From a setup perspective the holder keeps the rear body location repeatable, which can improve the consistency of aero behavior and weight distribution across runs. It is a practical choice for competitors refining shell fit or swapping bodies while keeping rear mounting accuracy.
