More Information

SKU HSD-G7X-Z identifies the Collins Hi-Speed® G7X "Super Dolly" Set Zinc Plated (equipped with T12 Hybrid Cross Rails), manufactured by Collins Manufacturing Corp.

Key Features & Construction Highlights

Heavy-Wall Steel Construction: Uses 0.180-inch thick steel tubing (up from 0.120-inch on lighter models) to handle deep pothole impacts, ditch extractions, and rough terrain.
Steel Hubs & Wheels: Replaces standard aluminum components with heavy-duty steel to prevent warping, flexing, or cracking under maximum loads.

Cross-Compatibility: Tires, wheels, and cross rail axles remain interchangeable with other Collins dolly models.
