50mm Ball Kit

  • Regular price $270.00


(50mm Ball Kit or Frame Adapter is included at no additional cost with each P360SD or HD purchased)

Trying to move anything more than say a 500kg jet ski trailer by simply using a standard 50mm ball will not work, like it does on a vehicle. You will constantly be fighting the handle as it dips or pushes up - you might even damage the mover or injure yourself!

At Parkit360 we use Stablelock technology to obtain a solid connection (no movement between the ball and coupling) to allow the Parkit360 to push/pull large trailers with easy. 

50mm Ball Kit (modified for Australian Trailers) includes:

  • Special 50mm Ball  (2" or 2 5/16" ball - can be ordered at additional cost)
  • Ball Mount
  • Tightening Bar
  • Thrust Washer 
  • Brackets

How does it work? 

Lower coupling onto the ball using jockey wheel. Lock into position with trailer latch. Tighten Ball Mount by hand till very tight. Tighten further with tightening bar. 

Note - Frame Adapter must be used (instead of the 50mm Ball Kit) if:

  • Caravan - has an off-road coupling (eg DO35)
  • Boat trailer - is mechanically braked (due to twisting of coupling, causing the Park360 to potentiall rollover onto its side).
