A dash means the listing does not narrow it down that far (for example no build dates are listed). Check with us if your vehicle was built near a model change.
Years are as listed by the manufacturer/supplier and may be US model years for US-built trucks.
Fitment listings are a guide. Not sure? Send us your rego or VIN and our team will check the part for your vehicle, before or after you order.

Warranty: 12 months from Willys Workshop
Sold and warranted by Willys Workshop. Parts carry our 12-month warranty against defects, from the date of purchase or installation (whichever is later), subject to any manufacturer terms and fair wear and tear (Terms & Conditions, clause 7.1(b)). This is in addition to your rights under the Australian Consumer Law, which cannot be excluded.
- 30-day change-of-mind returns on eligible items: unused, uninstalled and in the original packaging, with a Return Authorisation from us first. A 15% restocking fee applies and return postage is at your cost.
- Wrong fit: if a part covered by our Fitment Guarantee doesn’t fit, we pay the return freight both ways and there’s no restocking fee.
- Special-order or imported-to-order items, electrical parts, ECUs and tuners once registered, connected or flashed, parts that have been fitted or modified, and clearance items can’t be returned for change of mind. Your rights for faulty goods still apply.
- Refunds are made to your original payment method within 14 business days of us receiving and inspecting the return.
