So I got my 2.5" TF coil lift with bilstein 5100's installed yesterday and had a chance to take it out and see how it handled today. I'm impressed with how it looks and everything went on smooth no problems what so ever. A few bolts were a little hard to get off but other then that had it all completed in about 4.5 hours. I dialed in my speedo and did the TPMS delete with the SC Flashpaq. Very easy setup. Only thing I noticed was that it felt a little, I guess "flighty" around 60 km/h (40mph). Noticed a shimmy in the steering wheel and the jeep seemed to hunt around a little on the highway. Once I got it up to 100 (55-60mph) it was almost not noticeable. I have the JKS front adjustable track bar but no LCA's. Wondering if this may be the problem or what is causing the "flighty" feeling. Like I said it's nothing that's not tolerable just would really like to have it dialed in. The shop did an alignment and gave me a print out of the measurements. I've uploaded a picture of the measurements (might be hard to see) and wondering about the caster measurements. As you can see the front left is at 2.5 and the right at 2.9 deg. The other measurement that seems to be out of spec is the right front chamber at -0.8. Everything else seems to be good. Any knowledgeable member out there have any suggestions?

As for the tires the Duratracs are really really good. Got a snow storm moving in with heavy winds and it handled great in the hard pack and deep powder. Hit some ice patches as well and handled fairly well for the type of tire in my opinion. Definitely happy with my purchase so far...

 

I am no expert but read up on adjusting the toe in. I believe it helps with flighty feeling with larger tires. Jeep looks good. I have the same lift and sounds like the same driving conditions. My Jeep felt about the same before any mods though.

 

Camber can't be adjusted on a solid axle unless you have offset ball joints.
The wandering is from decreased caster from the lift. If you get some lower adjustable control arms and set them a little longer than your stock ones it will give you more caster. Seeing as though you have 2.9* that would surely cause some flightiness.
Many guys including myself like around 6* of caster. Any more and you start screwing up your pinion angle.
Nice Jeep BTW!

 

Toe measurements according to print out after adjustment are 0.10 left and 0.09 right and total toe obviously of 0.19

 

I have the exact same set up but 35x12.50x17 Toyo M/T. You described the exact way my Jeep used to handle. I do not have an adjustable track bar but the best thing i did was install a set of Lower Control Arms. A buddy in our local club gave me a set of RC LCA's from his 3" kit and ......A HUGE difference. Jeep is way less flighty and doesn't grab/wander hardly at all now. Made driving the Jeep on the highway a one handed job.

Your toe in is correct btw.
