| Suspension | Shock absorbers, springs, suspension arms, sway bars, and mounting hardware | Helps manage wheel movement, ride height, and handling response. | Aluminum alloy, steel, and engineered polymers | Check vehicle or chassis model, suspension geometry, mounting points, and intended ride height. | Drivers seeking more controlled handling or a setup suited to a particular course. |
| Steering | Steering links, bellcranks, servo mounts, and steering blocks | Transfers steering input to the wheels and supports consistent steering movement. | Aluminum alloy, steel, and composite materials | Verify steering-system layout, linkage dimensions, and compatibility with the existing servo and chassis. | Building, repairing, or adjusting a vehicle’s steering system. |
| Drivetrain | Drive shafts, differential components, gear hubs, and center-drive parts | Transmits power from the motor to the driven wheels. | Hardened steel, aluminum alloy, and reinforced composites | Match shaft length, gear specification, drivetrain layout, and the vehicle’s model version. | Replacing worn drive components or preparing a drivetrain for regular track use. |
| Chassis and Bracing | Chassis plates, braces, skid plates, and chassis supports | Provides the vehicle’s structural platform and helps support attached components. | Aluminum alloy, steel, and composite laminates | Check chassis generation, wheelbase, mounting-hole pattern, and clearance for adjacent parts. | Repairs, rebuilds, or setup changes that require a compatible structural component. |
| Wheels and Hubs | Wheel hubs, hex adapters, beadlock rings, and wheel-mounting hardware | Connects wheels to the vehicle and supports secure wheel installation. | Aluminum alloy, steel, and molded polymers | Confirm wheel size, axle dimensions, hub offset, and fastener type before ordering. | Wheel changes, replacement of damaged hubs, or adjustment of wheel fitment. |
| Braking | Brake discs, calipers, pads, and brake linkages | Creates friction to reduce wheel speed when the brake system is engaged. | Steel, aluminum alloy, and friction compounds | Check brake-system design, disc dimensions, mounting arrangement, and linkage compatibility. | Maintaining a compatible braking system or replacing worn brake components. |
| Cooling and Protection | Motor mounts, heat sinks, guards, and protective covers | Supports component mounting and helps shield selected parts from debris or impact. | Aluminum alloy, steel, and impact-resistant plastics | Confirm motor dimensions, chassis clearance, airflow needs, and mounting-hole positions. | Vehicles used on dusty, rough, or high-load courses. |
| Fasteners and Hardware | Screws, nuts, washers, spacers, and hinge pins | Secures assemblies and helps maintain correct spacing between components. | Steel, stainless steel, and aluminum alloy | Match thread size, length, head style, material, and the specified location on the vehicle. | Routine maintenance, assembly, and replacement of missing or damaged hardware. |
