Keep in mind that not every bull bar or piece of bar work will support the jacks.
There are extra attachments available for high lift jacks, these include a bigger base plate for the foot of the jack (the narrow foot is unstable the best of times), lifting hooks and extenders for the lifting tooth (lifting tooth as in the part of the jack which lifts the vehicle).
These jacks are also handy for bending and straightening damaged steering arms and pulling the weaker bar work back into shape. To do this kind of repairs requires a bit of creative thinking and some high lift jack attachments/accessories.
Many people have these attached to the outside of the vehicle, if doing this I would highly recommend oiling it from time to time to prevent rust and so it’s in working order for when needed.
