Once we’ve confirmed it fits your vehicle, our Fitment Guarantee covers it. If it doesn’t fit, we pay the return freight both ways and refund or exchange it. No restocking fee. How it works
Covered only after we confirm the fit from your rego or 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.
