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.

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.
