Collins Hi-Speed G7X Dollies with T12 Hybrid Cross Rails
Originally designed for Canada’s harsh off-road winters, the Collins G7X Super Dolly is built for extreme conditions and extended use. While the Collins G7 is the ultimate in professional, light-duty dolly towing, the G7X goes further with heavy-duty framework, tackling tough harsh road conditions, long-distance hauls and overall demanding wrecker jobs. See how it stacks up below.
Product Highlights
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.

This shock-assist action reduces driver fatigue and back injuries from lifting the side frames over the side of the truck bed. Buy now!
FAQ
Q: What makes the Collins G7X different from the standard G7 Dolly?
A: The G7X “Super Dolly” is specifically engineered for extreme, heavy-duty and off-road rural recovery conditions. Unlike the standard G7, the G7X features thicker steel construction, heavy-duty steel hubs, high-capacity steel wheels and steel cross-rail inserts to survive harsh winter environments and abusive towing conditions.
Q: What is the maximum weight capacity of the Collins G7X Dollies?
A: The Collins G7X features an industry-leading load capacity of up to 5,000 lbs. per pair, supported by aggressive, high-traction Load Range E (5.00 x 8) tires.
Q: What is the safe speed rating for towing with the Collins G7X Super Dolly?
A: The 5.00 x 8 tires on the G7X carry a speed marking of "M", which represents a safe towing speed rating of up to 75 MPH on expressways and highways.
Q: What is the recommended tire pressure (PSI) for the G7X Dolly?
A: To ensure safe operations, maximum load capacity and proper tire wear, Collins recommends maintaining a tire pressure of 120–125 PSI.
Q: Where can I find replacement parts like spindles or rail ends for the G7X?
A: Zip’s carries a full inventory of official Collins Manufacturing replacement components, including right/left spindle assemblies, replacement rail ends, tie-down straps, and hardware specifically engineered to fit the HSD-G7X model.
Q: How do I know if the heavy-duty Collins G7X is the right model for my fleet?
A: Choosing the right dolly depends heavily on the average curb weight of the vehicles you tow, the terrain you operate in, and how often the equipment is deployed. While standard, lighter-weight dollies are great for quick, short-distance highway runs with light passenger cars, the heavier-duty build of the G7X is designed specifically for extreme weather, high-mileage expressway trips and rugged off-road recoveries. To break down all the key differences, check out our comprehensive Tow Dolly Buying Guide on the Zip’s blog to make sure you make the right investment for your truck.
