Battery Hold-Down – Optima 34/78

Part number 248910 is a precision-machined battery hold-down system engineered specifically for Optima Group 34 and 34/78 batteries. The tray is CNC-cut from 6061-T6 aluminum and designed with a recessed pocket to cradle the battery base securely, preventing lateral movement during high-vibration or performance driving. The clamping arms span the top of the battery and fasten using stainless steel hardware, holding the unit firmly without stressing the case. Designed for both top-post and side-terminal Optima configurations, the hold-down offers both functionality and clean presentation in custom engine bays. The black anodized finish provides corrosion resistance while blending seamlessly with high-end build aesthetics.
