The Collins SLZ Hi-Speed®? Dolly Pro is a professional-grade tow dolly engineered for dependable performance, durability and versatility in demanding towing applications. Available in two configurations—the 5.70D (HSD-P5D) and 4.80D (HSD-P4D)—it gives towing professionals the flexibility to choose the tire size that best fits their needs.
Both models feature Collins T-10 telescopic aluminum cross rails with a 10-hole, center-cambered design. The rails measure 59" outside-to-outside when fully collapsed and provide up to 90" of usable span when fully extended. Collins' True Positive Camber design incorporates camber into both the rail ends and tubing material for reliable wheel positioning and a stable towing platform.
The HSD-P5D 5.70D features 5.70-size tires, while the HSD-P4D 4.80D uses 4.80 x 8 Load Range C tires. The 5.70 setup offers a rated capacity of 4,020 lbs.,, while the 4.80 combination offers a vehicle capacity of 3,968 lbs.
