Lastest Version Cruisemaster DO35 V3plus

Many of the Cruisemaster® team thought the DO35 version 2 (DO35v3) was hard to beat. However, once again, the engineering team has proven why they are the best in the business.

The new DO35 Version 3 (DO35v3) is the most robust coupling we have ever made; it even bent our test rig!

Tow Ball Hitches and Receiver Kits

Necessary: We recommend offroad couplings of all brands use a solid cast receiver hitch. Hollow receivers have a welded tongue that distorts in extreme offroad conditions and under shock loading events on the highway.

*New* V3Plus Exclusive Features

  • Patented “Check lock” Gen.2 Dust Cap & Bumper for an easy, secure seal
  • Improved Bumper moulding gives the reflector strip improved staying power
  • Rear support webbing allows for mounting upside down on the underside of the drawbar

* Checked on HR Classic, HR Standard, Milford and EZ-lift for compatibility with the DO35. The compatibility of WDH and Drawbar is a separate consideration.

*Please note that the DO35’s Zn-Ni with E-Coat provides superior protection. It may fade with extended exposure to UV. This does not affect the operation of the DO35. We recommend covering the DO35 coupling when not in use to maintain the product.
