The RUST Large Chassis is the frame used to facilitate vehicle modules, being the largest with 4 applicable slots. Facepunch added the modular vehicles in the Modular Vehicle Component Update on the 3rd of July, 2020.
Chassis types are spawnable in-game via the entity.spawn command, but are not available for research or crafting.
Most naturally spawning chassis types in rust are accompanied by a module type already included. Module types may be switched out once the chassis is placed on a powered Modular Car Lift.
For more information on modular vehicles, read our RUST Modular Cars Guide.
