Step Decks

XS Series: XS50, XS60, XS70

Step Decks

Lighter, Stronger, More Profit

Setting a new standard for long life and low maintenance, Extreme’s Step Deck (XS Series) trailers are the lightest and strongest on the market. Available in standard lengths from 48ft to 53ft, we also offer options for your special applications that include 28ft, 32ft, 45ft and 51ft lengths. Our patent-pending design, the lightest tare weight on the market, removes 1,000 lbs to 1,600 lbs of weight from the trailer and boasts 35%-50% stronger decking. When you add up reduced tare weight, reduced maintenance, reduced downtime, and better back hauls, you know it’s more profit to your bottom line.

XS50 Light, Strong and Industry Best Tare Weight

The XS50 series Step Deck is rated from 50,000 lbs. in a 4ft area, 60,000 lbs. in a 10 ft. area and a GVWR up to 90,000 lbs. and comes standard with an 11 inch neck. Our patent-pending decking design and Crush Resistant Technology (CRT) gives you unmatched deck strength and durability. 

XS60 A Versatile Trailer

The XS60 provides you with many options to customize your hauling capability. The low deck height, variable neck lengths, removable front and rear panels and separated air and brake lines are just some of the ways you benefit from trailers designed just for you. The XS60 load rating ranges from 60,000 lbs. in a 4ft area, 70,000lbs. in a 10ft area and a GVWR up to100,000 lbs., and 48ft to 53ft lengths with optional lengths available.

XS70 For Heavy Haul

The XS70 series step platform meets the needs of applications requiring higher load ratings without additional weight. It is rated at 70,000 lbs. in a 4ft area 80,000 lbs. in a 10ft area and a GVWR up to 120,000lbs. The XS70 is still one of the lightest on the market in its class and because of its patent-pending design, lowers maintenance and down time to increase back haul potential.
