All the style and features that have made the DO35 hitch an industry favourite are now available in a 4.5 tonne coupling. While the original concept for the DO35/DO45 range was focused on off-road use we have found over the years that this drop-On 4.5Tonne Articulating All-Terrain Pin Coupling has quickly become exceedingly popular on road vans as well; making it a great fit in all-terrains.

On Road Use- The inherit safety that comes with the articulation and ADR compliant locking mechanism of the DO45Plus means when the worst happens you couldn’t be in safer hands. If a roll over occurs when travelling the DO35 is less likely to disconnect or roll the vehicle with the caravan/trailer than many other couplings currently available. (Effectiveness of coupling in this scenario will be affected by towing peripherals such as WDH systems). Let’s not kid ourselves, you may start a trip with the best on intentions to keep to the flat top… But road conditions can change drastically and quickly! With the state of some “sealed” roads in Australia you may as well be on the dirt! The DO45Plus gives you the reassurance that your hitch can handle any road put in front of it.

Off-Road Use - When off-road articulation is king! Lets not kid ourselves most people arent taking their 4.5T caravan down the same tight tracks as those with camper trailers, but for those who are brave... The articulation of the DO45Plus allows you to explore more remote locations safely with its rotational articulation both horizontally and vertically.

But it doesn’t end there… when we talk off-road in Australia, we are largely talking tough corrugations, this is where the build quality of the DO45 Plus shines. Your coupling takes a beating on outback road, you will quickly find that only the toughest survive… the middle of nowhere isn’t the place to find this out! The DO45 Plus has high quality acetal bushes and is fully greaseable to reduce wear in the toughest of terrains.

Safety - The Cruisemaster DO35 V3 Plus and DO45 Plus Range of couplings have been designed with safety as a priority! The positive locking 2 stage ADR compliant locking mechanism gives you the reassurance that the vehicle and caravan and truly secured. The patented “Checklock” Gen.2 Cap also doubles as both dust protection and a fool proof safety check, the cap will only fit onto the coupling when the lock is activated… if the cap doesn’t fit your not ready to tow! Safety doesn’t end with the locking mechanism! Special consideration was given to the build materials, it was increasingly important to have the added strength to manage the additional forces added by a Weight Distribution System while keeping the unit slimline and light weight.

This was achieved by a combination of a forged steel Yoke and Rear Nut for strength where it matters and a cast Housing to reduce weight were not safety critical. We believe seeing is knowing; where others may be moving towards systems that enclose the safety critical locking components away from view we believe it is important to keep this components accessible and visible so you rest assured that a secure connection is achieved before travel. Low Profile - The DO45 Plus was designed with clearance in mind! Don’t let a grab handle or handbrake stop you from accessing your rear doors. The DO45 Plus has been tested on many of Australia’s favorite touring vehicles to ensure adequate door clearance.

Key Features:

• 4,500Kg Rated

• D-Value & V-Value ADR Compliant

• Patented “Checklock” Gen.2 Dust Cap & Bumper for an easy, secure seal

• Reflective Reversing Strip

• Rear support webbing allows for mounting upside down on the underside of the drawbar

• Plus all the design and function recognised from the DO35 V3Plus

• Handbrake included

Fitment:

• The Cruisemaster DO45 Plus uses a wider 4 bolt mounting pattern than the DO35 to allow for the more substantial build, meaning you may need to modify your mounting plate if upgrading from a different coupling.

• Weight Distribution Systems - It is important to note when selecting a WDH or tow tongue for use with the DO45Plus that you select a unit suitable for use with the 1 1/4" shaft of the DO45 Plus Pin.

• For instructions on installation, maintenance and use refer the DO45Plus User Guide. 

• *Please note while the DO45 Plus’s Zn-Ni with E-Coat provides superior corrosion protection it may fade with extended exposure to UV. This does not affect the operation of the DO45Plus. To best maintain the finish of the product, we recommend covering the DO35 coupling when not in use if stored outside and exposed to direct UV.

**Please note: DO45 Version 1 & DO45 Plus accessories and fittings are not interchangable
