Traxxas Traxxas Tall Battery Hold Down (7426X) is a tall battery hold‑down kit that replaces the standard battery clamp and retainers to allow installation of taller multi‑cell battery packs in compatible 1/10‑scale Traxxas vehicles. Designed with extended front and rear retainers, it secures the battery more effectively in low‑CG 4×4 and rally chassis configurations and lets you fit higher‑capacity LiPo packs without modification to the tray. This part is commonly used on models like the Slash 4×4 Ultimate and Rally variants equipped with the low‑CG battery compartment to provide reliable battery retention and improved fitment for taller packs.
