Beautiful Ramps
Our ramps are stunning.
Extended Size: 50" x 10-1/2'
Aluminum ramps come installed with ultra-wide SuperGlides™ to ensure a save ride up. These work great for sleds, ATVs, and side-by-sides.
Ramps can be powder coated for an additional charge.
Powder Coated
Quality is everything. Our decks are fully sandblasted and powder coated in-house with top of the line equipment.
Unlike paint, powder coating will last for many years to come without chipping, scratching, or weathering.
Illuminated
All of our decks come with white, amber, and red LED marker lights which interact with your trucks signal lights, brake lights, and running lights.
Underneath the deck is illuminated with three powerful LEDs, as well as the surface of the deck. This makes it even better in the dark.
Polyboard®
This is the only deck on the market that uses a Polyboard® composite surface.
It's eco-friendly as it's made form recycled materials, and it will withstand all of the elements.
Water-proof, weather-proof, decay-proof, UV resistant, freeze-thaw proof, and indestructible.
Expandable
Each deck is equipped with slide out width extensions that allow your deck's surface area to expand, or contract to your cargo.
It's as easy as removing a pin, and giving it a pull. Up to two snowmobiles can be hauled at once.
Weatherproof
Weather stripping can be added around the bottom side of the deck frame to make your cargo box weather proof (DIY).
Say no more to having snow, water, mud, and other debris contaminate your precious cargo.
L-Track
L-Track is outfitted on each side, and the middle of the deck surface.
This is the ultimate method of cargo securement, allowing thousands of different locations and options for tie-downs, cargo nets, Super Clamps™, and so much more.
