Radium Engineering Fuel Cell Weld-In Cage - RA-Series

The Radium Engineering Fuel Cell Weld-In Cage provides a purpose-built, professional-grade mounting solution for RA-series fuel cells. Engineered for motorsport environments where security and corrosion resistance are non-negotiable, each cage is fabricated from 1" x 1" x 1/16" stainless steel tube, TIG welded by hand and polished to a clean finish.

Unlike mild steel alternatives, the stainless construction is inherently rust resistant — critical in high-humidity or track environments where moisture exposure is unavoidable. The fuel cell sits snug within the cage and is secured using the included anodized aluminium straps, ensuring zero movement under hard cornering or braking loads.

Professional installation is required. Welding must be performed by a qualified fabricator.
