Collins Hi-Speed G7X Dollies with T12 Hybrid Cross Rails

Stronger, Heavier-Duty Build

Engineered with a significantly thicker steel construction, the G7X is built to absorb punishing roadside abuse, deep pothole impacts and rough ditch extractions. The beefy framework outlasts the competition, saving you money on replacements and minimizing fleet downtime.

Solid Steel Hubs and High-Capacity Steel Wheels

Equipped with a strong wheel assembly, the G7X features heavy-duty steel hubs and high-capacity steel wheels. This means zero flexing, warping or cracking when loading up heavy vehicles, giving you absolute peace of mind during high-stress recoveries.

Steel Cross Rail Insert with True-Positive Camber

Featuring Collins’ patented “True Positive Camber” design, the included T12 Hybrid Cross Rails combine adjustable aluminum outer tubes with an ultra-strong steel inner rail. This allows you to safely extend your span up to a massive 104" to accommodate wide vehicles, while ensuring the rails stay perfectly arched and never bow or sag under full load.

5,000-lb. Towing Capacity

Upgrade your fleet’s capabilities to handle heavy-duty trucks, large SUVs and commercial cargo vans with precision. These premium, high-traction tires support an industry-leading 5,000-lb. capacity, providing the biting grip needed to pull heavy loads out of muddy ditches or snowy embankments.

75 mph. Speed Rating

Never be a rolling roadblock on fast-moving highways. Fitted with heavy-duty tires carrying an official "M" speed marking, the G7X allows you to safely maintain expressway speeds up to 75 MPH over long distances, drastically reducing your transit times.

Built for Extreme Winters

Purpose-built to withstand harsh winter weather, the G7X delivers relentless structural resilience against freezing temperatures and corrosive road salt. When standard aluminum dollies slide or freeze up, this rugged system provides the heavy-duty traction and freezing-weather reliability required to get the job done safely.

Collins Self Loading Dolly Mount (Pair)

The Self-Loading Dolly Mounts from Collins are ideal for trucks with a taller bed height. These mounts drop down over the body side about 11" were it is then loaded, and then they swing up and back to the storage position. This shock-assist action reduces driver fatigue and back injuries from lifting the side frames over the side of the truck bed. Buy now!
