Shipping times vary depending on your location and shipping method selected during checkout. Standard shipping typically takes 5-7 business days, while expedited shipping can take 1-3 business days.

What is your return policy?

Returns are only accepted if Redo Package Protection was purchased at checkout, which includes a 14-day return window, free shipping, and no restocking fees. Exchanges are allowed with or without Redo, though non-Redo exchanges are subject to fees and shipping costs. All items must be unused, in original packaging, and meet strict resellable condition standards to qualify.

How do I know if a part will fit my specific UTV make and model?

Great question—fitment is everything when it comes to performance and safety. Every product page on our site includes a “Will this fit my machine?” section with detailed compatibility info. If you’re still unsure, give our team a call at 801-899-2520 or email support@r1industriesoffroad.com—we’ll confirm fitment before you buy, so you get exactly what you need the first time.

What happens if my order is damaged during shipping?

If you added Redo Package Protection at checkout, you’re fully covered! Redo handles lost, stolen, or damaged packages with zero hassle—just file a claim through the link in your Redo confirmation email.

What if I need to return something but didn’t buy Redo Package Protection?

If you’re unsure about an item, we recommend reaching out before you buy—we’re here to help you get it right the first time.
