Genuine Land Rover Parts
Genuine Land Rover parts for Defender, Discovery and Range Rover models, including TD5 engine components, seals, switches, cooling parts, body fittings, drivetrain components and original service parts.
Genuine parts are supplied under the Jaguar Land Rover parts programme and identified as Genuine Land Rover on the individual product page. Check the part number, vehicle fitment and any engine, model or early and late split before ordering.
Genuine Land Rover parts from Twinwoods 4x4
Genuine Land Rover parts remain the benchmark where exact original specification, fit or appearance matters. The range includes complete components alongside the small seals, clips, bolts, switches and fittings that can be difficult to match accurately with aftermarket parts.
| Parts required | Examples in this range | Check before ordering |
|---|---|---|
| TD5 engine and fuel system parts | Injector seals, filters, timing chain parts, sensors, fuel pressure regulators and engine sealing components | Check the engine type, part number and any early or late TD5 fitment split |
| Cooling system parts | Thermostats, coolant hoses, expansion tanks, bleed screws and sealing parts | Check the vehicle, engine and original part number |
| Electrical parts and switches | Window switches, brake light switches, horn switches, relays and lighting components | Check the connector, vehicle model and part-number supersession |
| Body, trim and exterior fittings | Badges, clips, seals, caps, lock parts, fasteners and model-specific trim | Check model, position, side and colour where relevant |
| Axle and drivetrain parts | Oil seals, drain plugs, CV spacers, gearbox fittings and related hardware | Check axle position, transmission type and original part number |
When Genuine Land Rover is worth buying
Genuine parts are particularly valuable where a component has an exact moulded shape, electrical specification, sealing profile, finish or fitment that is difficult to reproduce consistently. They are also often the best answer for obscure clips, fixings and small fittings where an almost-correct replacement can create more trouble than the saving is worth.
Check the part number
Land Rover parts can look identical while using different dimensions, connectors or internal specifications.
Check the vehicle and engine
Defender, Discovery and Range Rover models often use different parts despite sharing an engine or component description.
Check early and late fitment
TD5 fuel, electrical and cooling components can change by engine generation, model year or original installation.
Check what is included
Some genuine components are supplied individually, while seals, fixings or related parts may be sold separately.
