Ask The Expert- Switching from 4.5 Mid-arm to Long-arm

#1
Is this a correct complete list of parts needed to switch my 4.5 mid-arm to a long-arm kit?

I already have the springs and 6Paks, so just trying to make sure I'm not overlooking anything needed for this conversion.

JK Wrangler Replacement Brake Lines, Pair 26.5" Product Code: 1106
JK Wrangler Replacement Brake Lines, Pair 26.5" Product Code: 1106
JK 4 Link Long Arms, Upper Front Product Code: 7223
JK 4-Link Long Arm, Lower Front Product Code: 7224

JK Wrangler "DB3" Rear Control Arm Correction Bracket Product Code: 7197
JK Wrangler Sway Bar Link Extension Kit, 14.5" Product Code: 7221
JK Wrangler Long-Travel Durotrak Track Bar Kit, Rear Product Code: 7106

Recently went from 3-1/2 mid arm to 5-1/2 long arm, bought the kit since I needed springs, shocks etc. I also added the high steer kit but you may already have that.
Your list looks good except for an exhaust loop delete pipe which you'll have to get somewhere else. They make a "straight" pipe delete kit or a "horizontal" loop pipe kit so the stock loop doesn't interfere with the upper front arm bracket and travel.
I'd still give them a call though, they spent a lot of time on the phone with me comparing a complete kit to doing it by parts and answering all my questions.

Do you have a before and after pic?

+1 for the before and after (cause who doesn’t like pics??)

I’m definitely gonna call. But figured this could be a useful thread for others as well.

Good point about the exhaust loop delete. THANKS! [emoji3]

I'm not very good at stopping to take pics but found a few on my phone. The first is before from the Rubicon and the after is from McGee Creek in the Sierra's.
Kinda makes the 35's look small! [emoji848] 20170807_142610.jpg 20180802_131318.jpg
