Someone asked me if this would go high enough to do a clutch job. I took these pictures to show it is possible. This first one shows the lift in the lowest position, with one of the jack stands I used for my clutch jobs in its highest position as I used it.
This second picture shows the lift in its highest position. The point I used to place the jack stand is about 4 1/2" higher than what it was on the jack stand.
