HPI Baja Rear Skirt Precision Upgrade BJ903R by GPM  [BJ903R]

Precision rear skirt for HPI Baja chassis reinforcement

The BJ903R aluminium rear skirt is engineered as a direct replacement to strengthen the lower rear body on HPI Baja-style shells. Manufactured to tight tolerances, the skirt mounts to the factory body or bumper points to increase rear rigidity and abrasion resistance without complex modifications.

Installation follows standard body hardware locations; the part is intended to use existing posts and fasteners where practical. Typical fitting steps include removing the rear shell, aligning the skirt to the mounting tabs, and securing with original or supplied fasteners. No specialised tools are required beyond standard hex drivers.

As a chassis-level tuning component, the added stiffness from the alloy skirt alters rear-body dynamics and debris flow. For setup and performance tuning, start with baseline suspension settings, then refine shock damping or toe to achieve the desired rear traction balance.

Specified for hobbyists seeking a robust, accurately fitting rear lower skirt for Baja shells; confirm fit before final finishing.
