Product Highlights

Ultra-Lightweight Aluminum Build

Designed to help you work fast and efficiently, the G7 HERO features premium aluminum components including aluminum wheels, cross rails and a lightweight pry bar. By drastically reducing the physical effort required to lift, transport and position the dollies, this system helps prevent operator injuries and keeps your team moving safely.

Greaseable Aluminum Hubs and Aluminum Wheels

Engineered for long-term durability and effortless maintenance, the HERO line features specialized greaseable aluminum hubs paired with high-strength aluminum wheels. This setup provides smooth rotation, exceptional heat dissipation, and simple servicing to maximize your uptime.

Patented Positive Camber Axles

Eliminating rail sag and dragging on bumpy roads, the HERO line axles are engineered with a precise, engineered bend. The slight bend creates a true positive camber that actively supports the vehicle when fully loaded, ensuring maximum ground clearance and significantly reducing your steering effort during tight turns.

Up to 4,280 lbs. Towing Capacity

Upgrade your light-to-medium fleet capabilities with two high-performance tire options. Choose between the agile 4.80 x 8 setup supporting 3,968 lbs. or step up to the robust 5.70 x 8 configuration to safely handle up to 4,280 lbs. of vehicle weight.

No Towing Distance Restrictions

Pull with total confidence across city lines or across the country. These tow dollies are rigorously tested and fully approved for continuous freeway, highway and interstate use—proven to comfortably handle over 1,600 freeway miles in a single, uninterrupted tow.

Integrated Secure Ratchet System

Equipped with more built-in safety features than any other dolly manufacturer on the market, the system utilizes a rugged, integrated ratchet tie-down mechanism. Once clicked into place, you know the towed vehicle is locked down tight and isn't going anywhere.

Flexible 104" Usable width

Seamlessly adapt to any vehicle track width on the fly. The aluminum cross rails easily collapse down to a compact 66" for clean, space-saving storage on your truck, and smoothly telescope out to a maximum usable width of 104" to secure wider cars and SUVs.

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.

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.

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.

Whether you're operating a wrecker, car carrier, or rollback, a tow dolly minimizes setup time and maximizes job efficiency.

Ease of Storage

Folding or stackable models help you maximize truck bed or garage space.

Material & Finish

Aluminum options (like G7) are lightweight and corrosion-resistant; zinc-plated steel (Hi-Speed) emphasizes toughness.

Parts Availability

Having access to axles, straps, hubs, and tires helps avoid downtime during peak jobs.

 

Accessories & Parts Are Ready for You

FAQ: Tow Dollies

What is the typical capacity of a tow dolly?
Most professional models carry between 3,000 and 5,000+ lbs. Always confirm your vehicle's curb weight before towing.

Are these tow dollies suitable for RVs?
No—these models are for front-wheel-drive cars and light trucks only. They are not designed for RV towing.

How do I maintain my tow dolly?
Check axle bearings, tires, straps, and hardware regularly. Use original replacement parts for best performance.

Why choose aluminum vs. zinc-plated options?
Aluminum (e.g., Collins G7) is lighter and corrosion-resistant—great for storage. Zinc-plated steel (e.g., Collins Hi-Speed) offers extreme durability in heavy-use scenarios.
