If you're running a lift on your Jeep JK Wrangler and flex out the suspension on a regular basis, you may find that your rear sway bar had a tendency to shift to one side or the other. For the most part, this is no big deal but in some cases, the sway bar can shift enough to where the arms and or link ends catch on the frame causing a loud noise or sometimes even your brakes hard and/or soft lines causing damage to them. Fortunately, there is a cheap easy fix for this and this write-up should be able to help you out.
What you will need
(2) 11/16" Diameter Extra-Grip Two-Piece Clamp-on Shaft Collar
• 1/4" Allen Wrench
• Pry Bar
• Frame Paint
Installation
Here's a photo of what the Extra-Grip Two-Piece Clamp-on Shaft Collar will look like.

1. The shaft collars that I bought are black-oxide steel and while they do offer some corrosion resistance, they will develop some surface rust over time, even in the best of conditions. Because of this, I elected to spray some frame paint prior to installation.
2. If needed, use a pry bar to help you pull your JK rear sway bar back to center again. As you can see, I am running a factory JK rear sway bar on my EVO Lever but the process will be the same for a JK with standard factory setup.
3. Place the 2 halves of the shaft collars on to your JK's rear sway bar and up against the inside of the driver side frame mounted bushing as shown in the photo below. Use an 1/4" allen wrench to secure them in place.
4. Repeat step 3 on the passenger side of your Jeep.
Finally, here's a photo from further back to show what the shaft collars will look like installed on your JK rear sway bar. As you can see, they are hardly noticeable.
That's it! Your JK rear sway bar should now stay put and no longer shift around. Because I chose to order up a set of Extra-Grip shaft collars, they ended up costing me $26 but, you can use standard shaft collars and they will cost less. I ordered my shaft collars from McMaster Carr and the part number for them was #8386K38. They are sold individually so you will need to order 2 of them. I hope this helps you out.
