I have a 2014 JKUR that is mostly a street truck/ weekend toy. I just added a 2.5 AEV lift and 35's with rims at 4.5 backspacing. Obviously I had the aliment checked and that is off no big deal to fix that but I was also told by the shop I need a front adjustable front track bar and that the jeep is dogtracking a bit. I went the the AEV site and they seem to be pushing the JK Geometry Correction Front Control Arm Drop Bracket. I have done some searching here on the forum and now I am thoroughly confused. Price is pretty similar either way but what is the better option? Thanks you in advance,
Read the first three sentences you wrote, alignment is off because the axle has shifted, track bar will fix that. Until it is fixed it will dog leg. You gave info and answered your own question along with the alignment guys input. Now simply fix it and down the road you are. Enjoy
You should definitely get the control arm drop brackets. They will correct your caster, and provide a better ride by angle correcting the control arms. Looks like AEV leaves them out to keep the kit cost under $1,000. As for the track bar, I put one of these on a club member's JKUR and the axle was centered to within 1/4" side to side. Ideally you want it on the money, but if they put the supplied AEV rear bar & bracket on it shouldn't "dog track" at all with the axle that close to dead center.
i have the AEV 2.5" myself with 35s and i ran without the Geo correction brackets for about 4 months.. just put them on today and the difference is literally night and day! truck tracks straighter, steering is more precise, and less unpredictable when you hit a nice bump in the road.
Visit Synergy suspension.com and read up on the frame brace and sector shaft brace. The main difference in trackbar brands besides bushing material and joint type is compatability between joining the above parts with any other brand of trackbar.
