A lifter is the same as a Jack plate over here - may be different in the States though! A jack plate actually lifts the whole engine up and down - do you mean trim tabs and smart tabs? If so it would depend on the application and there is quite a bit on here on different threads - if you use the search function you may find the information you're looking for!
