I've got a 3" dropped axle from Sid and I flipped the tie rod ends to ride underneath the steering arms. I have a little over 1" of clearance under the spring pack. Looks to me like you have 2 options here: 1. Do the tie rod flip AND heat and bend the steering arms down until you clear under the springs. OR -
2: Trade your 4" axle for a 3". You'll still need to do the flip but they will clear the springs.
I'd measure carefully before using option 1. You don't want your tie rod riding below the scrub line.
Good luck, and keep us posted.
