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

Rear lower skirt in aluminium for HPI Baja

The BJ903R alloy rear skirt is a purpose-built replacement intended to stiffen and protect the lower rear section of HPI Baja-style bodies. The item mounts to existing body or bumper fixings and provides a tougher rear profile that resists flex and abrasion during off-road use.

Fitment uses standard Baja body hardware points and commonly reuses the vehicle's fasteners and body posts. Installation normally requires removing the rear shell, lining up the skirt on the factory tabs, and fastening it with the original screws or the supplied hardware. Only basic hex drivers and hand tools are required.

From a setup angle, the added rear stiffness will influence airflow and debris deflection behind the bumper. Begin testing with your usual suspension and tyre choices, then adjust shock or toe settings if the altered rear stiffness affects traction or stability.

Fit this alloy skirt when you want increased rear lower-body durability and stiffness for rough driving; always trial-fit to your specific shell before finishing work.
