Watch the Stretched Out online guitar lesson by Brad Carlton from Chord Studies: Rock and Pop Progressions Vol. 2
In this example you'll be using the same left hand shape in three different positions to get the chords in this progression. It's important to keep your fingers upright, but your fourth finger is going to deaden the third string. If you're having trouble with stretching, the key is to think right to left. Putting your fourth finger down first and then adding the rest of them accordingly will help you find the ideal position for these chords without running out of finger stretchiness.
