Extreme Terrain uses several trusted carriers to ensure the efficient delivery of its products. For standard shipping, they rely on USPS, UPS, and FedEx, selecting the most cost-effective option based on the shipment’s weight and destination. For large or oversized items, Extreme Terrain partners with third-party freight carriers, ensuring safe and reliable transportation.
Orders placed Monday through Friday before 4:00 PM ET are shipped the same day, provided the items are in stock and free of verification flags. Standard shipping takes 3 to 5 business days for delivery, while expedited shipping options like 1-Day, 2-Day, and 3-Day guarantee delivery within their respective timelines.
Extreme Terrain was co-founded by brothers Andrew and Steve Voudouris, with Steve Voudouris currently serving as the company’s President and CEO.
Instead of an upfront percentage off at checkout, Extreme Terrain's program awards you XT Cash Rewards after verification through SheerID. You earn 5% back sitewide on third-party parts, 10% on select house brands, and 20% on Open Box items, which post to your account within 24 hours of shipping and expire after 90 days.
While they started as independent rivals, they are now corporate sister sites owned by the same parent company, Turn5, Inc. To streamline logistics, Morris 4x4 Center completely integrated its digital storefront and distribution network into ExtremeTerrain. Today, they share the exact same inventory tracking, checkout pipelines, and customer support infrastructure, making them essentially the same platform under different names.
