The DragRace Concepts Maxim Adjustable Front Bulkhead is a fully machined, aluminum front bulkhead that features interchangeable caster a-arm mounts. The included mounts provide 1.5 degrees of caster and optional brass mounts are available separately (DRC-10104). This is a replacement for the DRC Maxim chassis, but can be used as a tuning option on DRC1 Drag Pak mid motor and rear motor chassis as well.
