Collins SLZ Hi-Speed® REPO Dolly HSD-R4D
The Collins HSD-R4D is the REPO configuration of the SLZ Hi-Speed® dolly: a 3,640 lb, 65 MPH highway-rated tow dolly built for repossession work and everyday light-duty towing. It runs the same proven SLZ frame and aluminum running gear as the PRO, with steel wheels in place of aluminum.
Why the SLZ REPO
- Proven platform. The SLZ is Collins' sixth-generation Hi-Speed® dolly, in service since 2016.
- Safety Ratchet System. Collins' patented ratchet holds the vehicle up and resists unintended lowering during loading.
- True Positive Camber cross rails. Keeps the dolly tracking straight and the tires loaded evenly at highway speed.
- Greaseable aluminum hubs. Simple routine service. See the operations manual below for intervals.
