The height of Double Jacks is 13cm in packaging which works for almost every car.

We have reduced the min. height of Double Jack from 172mm to 130mm in the new desiging, the lenght of post for small jack is reduce from 80mm to 65mm, so the small jack has more power to lift the car at beginning. We  installed and tested it in Jan, 2024.

We have lift the vehicle several times. The Double Jacks  was rised from 200mm to 245mm, and 265mm to 286mm in last tests in March 2025.
