FAQs

Please read our FAQs page to find out more.

What is the ETA for Forged wheels?

Most of the forged wheels we offer are custom-built to order for your specific vehicle. Current estimated production time is 5–6 weeks. Certain finishes, such as Chrome, Two-Tone, or Brushed, may require an additional 1–2 weeks for completion.

Your patience ensures a perfect fit and premium quality—thank you for your order!

Will this fit my car?

All of our products come with a **perfect fit guarantee**—if it doesn’t fit, you get your money back!

Can I cancel my order?

All forged wheel purchases are final sale and non-refundable. If you need to cancel a custom order, we can issue store credit for future use.

For in-stock (inventory) wheel orders, cancellations are subject to a 25% restocking fee.

By completing your purchase, you acknowledge and agree to these terms, including waiving the right to file a chargeback.

Thank you for understanding our policy—we’re here to assist with any questions!


Why? Forged wheels are custom-built for your vehicle with custom specs, colors and design, so we can’t resell them. This policy helps us keep prices fair while ensuring quality craftsmanship.
