ADDCO Rear Sway Bar Kit Reviews

Top notch product! Use silicone grease on the bushings in the hole and on the bar during assembly. They won't squeak! Don't use wheel bearing grease!!!
Questions
James W.
I am interested in buying this 7/8" rear sway bar -
That will increase the strength versus the factory sway bar BUT there are 2 vertical bars about 9" long each, also used to attach the sway bar.
I would think those would also come with the kit, because if you keep the factory bars, which transfer pressure to and from the sway bar to the body...haven't accomplished much.
I see a few such vertical bars elsewhere on your site but want to be sure those I buy are matched to the strength of the 7/8" Addco sway bar.

The vertical bars you are referring to are the sway bar end links, and your concern is spot-on—retaining weak or worn factory end links when upgrading to a stiffer 7/8" heavy-duty sway bar would introduce flex and rob the new bar of its performance benefits.
For the ADDCO Rear Sway Bar Kit for 99-04 Jeep Grand Cherokee WJ, here is how the end links are handled:
What's in the box: The ADDCO sway bar kit primarily includes the heavy-duty 7/8" solid steel sway bar and new polyurethane bushings. Typically, ADDCO kits for this application are designed to reuse the factory mounting locations and often rely on the existing end link configuration or include basic hardware, but they do not always come packaged with heavy-duty replacement end links.
Upgrading the Links: Because you want to match the rigidity of the 7/8" bar and avoid slop in those 9" vertical links, you do not need to guess or piece together random parts. Heavy-duty aftermarket sway bar end links (or OEM-style heavy replacements) designed for the WJ platform will bolt right up and safely handle the increased torsional load of the thicker Addco bar without flexing.
