Known in the US as the DO45 off-road hitch, the Cruisemaster DO45Plus is a 4,500kg-rated articulating pin coupling for on-road and off-road towing of heavy caravans and trailers. Building on the proven DO35 platform, the DO45 adds capacity and enhanced features for those needing to safely tow up to 4.5 tonnes across all terrain.

Rated Capacity: 4,500kg (9,921 lb) | SAE J684 Class 4 (USA) | ADR Compliant | D-Value & V-Value Certified

  • 1 1/4" (32mm) tow pin included — ensure your tow tongue or ball mount can take a 1-1/4-inch shank before ordering
  • Drop-on design — quick, convenient trailer connection without a ball hitch
  • Dual-axis articulation — maximum approach/departure angle capability for on-road and off-road
  • Positive Interlock 2-stage locking — ADR-compliant secure attachment
  • Patented Checklock Gen.2 dust cap — only fits when lock is fully engaged; foolproof safety check before towing
  • Reflective reversing strip — easy trailer alignment in low light
  • Rear support webbing — allows upside-down mounting on underside of drawbar
  • Fully greaseable — high-quality acetal bushes reduce wear on tough corrugations
  • Towpin cover included for pin protection when not in use
  • Includes 1 1/4" tow pin, pin cover, Universal C-Spanner, mounting bolts, and user guide

Note: The DO45Plus uses a wider 4-bolt mounting pattern than the DO35. Check your existing mounting plate if upgrading from DO35.
