Features & benefits

Hardox® In My Body Certified

The Neustar Pup Tandem trailer is Hardox® In My Body certified, assuring you that we built it to the highest standards, giving you unsurpassed performance and durability. Hardox® is 5X as strong as mild steel, and much lighter. It can double the life of your equipment and increase your payload capacity and fuel efficiency.

The Toughest Frame

The frame web and flanges of our Pup Tandem trailer are built with Strenx® high tensile steel. Strenx® is twice as strong and 30% lighter than commonly used structural steel. With a wider frame stance, Neustar Pup trailers are more stable than the competition. Reduce the trailer’s weight while increasing your payload and performance.

Superior Suspension

Our Pup Tandem Trailer comes standard with IMT air ride suspension featuring larger and more stable airbags. Their 30,000 lb weight capacity per axle increases your payload by 20% over the competition.

Top Quality Finish

Neustar Pup trailers are first sandblasted, then primed and top coated with Dupont® polyurethane giving a flexible surface that is resistant to chemicals, weather, humidity, and abrasions. Our attention to every detail gives you superior quality and superior looks.
