Your exact vehicle must be listed in the Fitment tab or confirmed by rego/VIN. Tell us within 30 days, with the part unused. Special-order, freight-quoted and tune/software items are excluded. Change of mind is different: 30 days, a 15% restocking fee, and you pay the return postage.

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.
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.
