Hey about the steering stabilizers if you have alot of shake in your steering chances are somthing is wrong under your front end stabilizers only hide the real problem. check your steering system for any loose parts or play in parts that shouldnt have play check your tires are for proper inflation check your alignment and balancing. check everything.
K now that thats out of the way i have an 08 jk with 35x 12.5 had a small shimmy between 30-40 mph i bought the dual steering stabilizer kit from rough country cleaned it right up doesnt do it anymore the problem i had was the tires arent made axactly round and the balancing was a little off. the kits are fairly easy to put on mine took roughly 30-45 mins. not to mention they look great but like i said make sure nothing is wrong before you go and get a kit and slap it on or it will lead to problems later on.
