Powderkeg LLC Ski-doo storage boxes are absolutely the best boxes in the business. Better quality and much more ergonomic than the Ski-doo LYNQ system (and nothing breaks in the cold) . These are so strong you can stand on them. This box fits the 146" up to 174" sleds ( and 137" sleds without the led taillight system). Life kits (shovel, flashlight, saw, waterproof container) are available for an additional $100 and must be ordered with the box not separately-call to order-it is a lid with all these built-in. We tried them all including the soft storage options and although a little pricey these are worth every penny!
Check out the fuel caddy's that can be purchased and installed right under the storage boxes!
