Parts Availability
The practical reality of owning a UK ZJ is that American mechanical components are readily available — RockAuto in particular has outstanding stock — while UK body panels, some electrical components, and RHD-specific parts like headlamps are genuinely difficult. Build US sourcing into your ownership budget from the start.

UK Suppliers
UK ZJ specialist with direct experience of RHD cars. Good for parts that need UK-specific knowledge and where you want to speak to someone who knows the car. Worth calling before ordering from the US — they may have what you need in stock.
The best combination of price, availability and shipping speed for mechanical components. The catalogue is comprehensive and the ZJ is extremely well covered. Select OEM or reputable brands — don't default to the cheapest listing on safety-critical parts. Shipping to the UK is reliable and typically reasonable. This should be your first call for most mechanical parts.
Good for next-day UK delivery on suspension and brake components under Febi, TRW, and Meyle brands. Ball joints, tie rod ends, and wheel bearings are often stocked. Use when speed matters more than price.
The world's largest dedicated Jeep parts retailer. Particularly strong on interior, body, and trim items that RockAuto doesn't cover. Ships internationally.
A legitimate source for NOS parts and salvage items — particularly ZJ-specific electrical and trim components that aren't stocked elsewhere. Search by part number. Be cautious with cheap pattern parts on steering and suspension.
