Collins SLZ Hi-Speed® PRO Dolly HSD-P4D
The Collins HSD-P4D is the PRO configuration of the SLZ Hi-Speed® dolly: a 3,968 lb, 65 MPH highway-rated tow dolly set with all-aluminum running gear. It's the all-around wrecker dolly for everyday car and light-truck tows.
Why the SLZ PRO
- Proven platform. The SLZ is Collins' sixth-generation Hi-Speed® dolly, in service since 2016.
- Aluminum wheels and hubs. Aluminum wheels instead of the REPO's steel, plus a higher capacity rating on the same 4.80 D-rated tires.
- 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.
Want the G7's self-lubricating bushings, or more capacity from 5.70 tires? Compare the full Collins lineup in the table on this page.
