Weighing only 54 lbs. with a payload capacity almost 60x its weight (3040 lbs. up to 4280 lbs.*)
Safety Ratchets prevent accidents, allow mobility in tight spaces and better leverage on snow, ice, gravel & slopes - more safe options in difficult situations. Safety First!
Serviceability has never been easier–replace components on the spot!
Parts are conveniently distinguished by gold tone for quick identification and easy replacement.
State of the art engineering with the first 8 x 3.75 aluminum mag wheel and matching slotted aluminum hub.
Hi-Speed® Dolly Instructional Video
Collins dual-tone zinc plating comes standard with the SLZ Hi-Speed® Dolly as a durable anti-corrosion finish to weather the most severe conditions.
Aluminum Wheel & Hub
The wheel reinvented: Collins Diamond-Cut Polished Aluminum Wheel and matching slotted Hub allows dynamic air flow through the openings, meaning hubs and bearings last even longer while reducing overall dolly weight.
Collins Dollies are a prime mover - you can safely tow vehicles on the dollies for miles. Grease points keep the Hi-Speed® Dolly lubricated under many tows for longer periods of time.
Dolly Weight (per side): 54 lbs. (4.80 x 8) & 60 lbs. (5.70 x 8)
Static Payload Capacity: up to 4280 lbs. (using 5.70 x 8 tires) & 3040 lbs. (4.80 x 8 tires)
*Caution - moving forces increase load on dollies. Plan accordingly, use tie-down straps and drive safely.
Lift Clearance (measured from dolly): 7-inches (4.80); 9.5-inches (5.70)
Tire Pressure: Factory-released 60 PSI; Wheels rated up to 100 PSI
*Adjust tire pressure as needed for towing conditions
