Kojack High Lift 4 Tonne Hydraulic Jack Lift to 750mm
Take the hassle out of caravan / 4WD / boat trailer lifting with the Kojack High Lift, by Purple Line. This high lift model adds an additional 150mm extension for added height for a total lift to 750mm. The ideal hydraulic caravan jack for safe, easy lifting of even the heaviest Aussie caravans and is RVS tested and certified to Australian/New Zealand Standard AS/NZS 2693:2007.
Versatile and smooth, Kojack comes with ball and block fittings to suit most Australian caravans and mounts to the chassis, so it won’t compromise jockey wheel mounts. And with a lifting range of 220mm and a massive 4-tonne capacity, it remains lightweight at just 12kgs even with all the additional fittings. Great for Caravans, RVs, 4WDs and Boat Trailers.
It’s no surprise that Kojack is standard in all OPUS Caravans!

I purchased the Kojack as a backup jack prior to commencing my off grid camping trip along the Murray River. A great product when my trail a mate failed! Saved me a lot of time and grief when I couldn’t raise my van. In 2 weeks I’ve used it twice now Very compact and easy to use
