Great bit of kit. Bought because I wanted a single jack for the car and the van. The Kojack has enough travel to lift a 4WD with independant air suspension as well as the van.

Great piece of gear every caravner should have
Quality product. The high lidt jack supplied with our 21foot van broke first time so we replaced it with Kojack 4t. This is a bottle jack so of course it is much lower lift so we got it with the higher extension. Ours is a very high van so I still need a decent block of wood under it. The mechanism is good, operates smoothly and comes in a neat bag for easy storage. Quite satisfied.
doesn't release easily so needs to be manually pushed
Great jack and extension kit, good when you need extra length and fitting or jacking up againstsurfaces.
Really good solid jack for my caravanWith handy extensions including a ball and Square head fitting
This is a great size to have packed away (not balky) like other jacks & can lift more weight also comes packed in its own carry bag with attachments that's why I rate this product with 5 ⭐️ ⭐️ ⭐️ ⭐️ ⭐️
Excellent customer service, product is exactly what I required - highly recommend caravan RV camping. Thanks
