New Jet Trailers For Sale in Colorado

New Jet trailers in this category are primarily side dump trailers built for aggregate, dirt, demolition debris, asphalt millings, and other high-cycle material hauling. Jet side dumps are known for stable unloading on uneven ground compared with end dumps, which matters on road jobs, site development, and shoulder work where overhead clearance or soft footing can limit where you can safely dump. For buyers in Colorado, that makes side dumps a practical fit for mountain work, municipal projects, quarry runs, and construction fleets that need quick unload times without the height of a raised end dump.

The core spec decisions usually start with trailer length, axle configuration, tub design, and suspension. Common examples include 40-foot tandem axle trailers and longer tri-axle layouts around 46 feet. Many Jet side dumps use round bottom or rock tub designs with 1/4-inch AR400 steel for abrasion resistance and longer life in gravel, riprap, and demolition applications. Tandem and tri-axle versions paired with air ride suspension help balance payload, ride quality, and site manners. Tire sizes such as 11R22.5 and 11R24.5 are common, and steel wheels remain a typical choice for vocational durability.

A buyer should pay close attention to the dump system details because that is where productivity and longevity show up. Jet side dumps commonly feature inverted trunnion-mounted cylinders, four pivot points per side, and a 2-way directional valve to support smooth, controlled dumping to either side. Engineered tub corners are a notable design point because cracking often starts in high-stress transition areas on hard-used dump trailers. Electric roll over tarps, tarp lockout switches, push blocks, LED lighting, front and rear fenders, and 2-speed landing gear are all common vocational specs that reduce setup time and keep the trailer practical for daily site work.

When comparing new Jet side dump trailers, focus on payload target, legal bridge needs, material type, and the jobsite conditions your drivers deal with most often. A tandem 40-footer can be a strong fit for general construction and tighter access, while a tri-axle may make more sense when bridge law, weight distribution, or volume capacity pushes the decision. Also consider liner and tub wear expectations, hydraulic compatibility with your tractors, kingpin setting, and how often the trailer will dump on crowned, soft, or uneven surfaces. In this class, the best trailer is usually the one that matches the material stream and route profile as closely as it matches the spec sheet.
