Collins G7X Hi-Speed® Dolly
SKU: HSD-G7X
Originally built for Canada's harshest off-road winters. Steel hubs, eXtreme capacity steel wheels, and patented T12 Hybrid Cross Rails give it the highest capacity and highest speed rating in the Collins lineup.
Collins Hi-Speed® Dolly – G7 (7th Generation) Pro HSD-G7-P5D
SKU: HSD-G7-P5D
The 7th-generation G7 body with the larger 5.70x8 D-rated tire — Collins' highest freeway-approved capacity short of the G7X. CNC-machined spindles and self-lubricating composite bushings mean less downtime.
Collins Hi-Speed® Dolly – G7 (7th Generation) Pro HSD-G7-P4D
SKU: HSD-G7-P4D
Get the World's Most Advanced® dolly body without overpaying. Same G7 upgrades — ergonomic motorcycle-style handle, zinc-plated frame, CNC shoulder bolts — paired with the lighter 4.80x8 D-rated tire.
Collins SLZ Hi-Speed® Dolly Pro 5.70D
SKU: HSD-P5D
Collins' tried-and-true 6th-generation SLZ body, built since 2016, now paired with the larger 5.70x8 D-rated tire for the highest capacity SLZ available — full capability at the most economical price point that still hits 4,280 lbs.
Collins SLZ Hi-Speed® Dolly PRO (6th Generation)
SKU: HSD-P4C
The lightest, most affordable way into the Collins Hi-Speed® lineup. Since 2016 the SLZ has been the fully-capable, no-frills choice for shops that want proven reliability at the lowest entry price.
