The length of the club has an effect on distance since it affects clubhead speed, but I don't think you will necessary get more distance.

Distance is also produced by hitting the ball off the sweet spot of the club and and with a longer club, you are less likely to hit the sweet spot.

Also, not all brands of clubs use the same loft angles and this is a major determinant of distance. So you may gain or lose distance depending on the loft angle. On Kmart clubs the quality control is probably not great and the loft angle will not alway be what they are supposed to be. Even on well made name brand clubs there is some error on the loft angles.
