5	Driver Cab 6 parts	1×	Driver cab
6	Ladder Frame Rails	1×
7	Wheel Assembly 5 parts	4×	Complete road wheel: rim, tyre, valve, pressure sensor, and fasteners, balanced and ready to bolt onto the hub.
8	Brake Corner 4 parts	4×	Complete brake at one wheel: disc, caliper, pads, and hose, assembled to the hub.
9	Suspension Corner 5 parts	4×	Complete suspension at one wheel: control arms, spring, damper, hub, and joints.
10	Steering Rack (EPS) 4 parts	1×	Electric power steering rack combining the rack and pinion gear, the assist motor, torque sensor, and tie rods.
11	Open Differential 4 parts	1×	Open bevel-gear differential that splits drive torque between two wheels while letting them turn at different speeds in a corner.
12	Radiator	1×	Finned aluminium heat exchanger that passes hot coolant through thin tubes so air flowing across the fins carries the heat away.
13	Coolant Pump	1×	Electric or belt-driven centrifugal pump that circulates coolant through the engine, motor, battery, or heat exchanger.
14	Coolant	1×	Water and glycol mixture with corrosion inhibitors that carries heat through the cooling circuit without freezing or boiling.
15	12 V Battery	1×	12 V lead-acid or lithium battery that powers the vehicle's low-voltage electronics and starts or wakes the main system.
16	LV Wiring Harness 4 parts	1×	Low-voltage wiring harness distributing 12 V power and signals to lights, sensors, switches, and control units.
