OEM+ Tall 3D-Printed Battery Cover for Onyx RCR (V1.5)
Maintain the clean, factory look of your Onyx RCR—while gaining extra room under the hood. This OEM+ style battery cover is modeled after the original design but adds an additional 7/8" of internal clearance, giving you more space for larger or custom battery setups without sacrificing style.
