Here's a shot of us using the high lift jack to change the springs in our RK 1.5 budget build.

REMEMBER - this is not what this jack is for. The only reason it was ok in this instance is because we were not taking the wheel off. AND i had jackstands to back it up in case of failure.

We were in a jam where we couldn't get the spring to release with our standard jacks.
