Oversize (or LTL) items are larger than what can be shipped through regular mail. Oversized item returns cannot be initiated online.   Call Polaris Customer Service at 1-800-303-9002 in the U.S. and 1-800-304-6067 in Canada. Have your order number and packaging slip ready, along with the item numbers you want to return. A Customer Service Rep will step through your options and set up a return authorization. You will receive an email that includes your return number and complete return instructions.
