Handling issues

I just had a 3.25 inch suspension lift with 295 70 18 terra grapplers installed. At speeds of 60 or so, the back end feels as if its chasing the front? What can I do to fix this issue?

Adjustable control arms, adjustable track bars, geo correction brackets, tire pressure, longer sway bar links. You didn't give any info on what your kit included so these are a few things that could help your handling issues. Oh and better shocks, better springs, check torque on components, rotate tires, the list goes on

Nice looking Jeep BTW

There's your problem. A low end suspension lift at a higher height without the parts to make it work.

First I would (if not done) loosen all the TB bolts and control arm bolts w/ tires on the ground. Shake around/jump on bumpers. Then torque to spec.
Just a guess here, but I am assuming this wasn't done and put a awful bind on the stock bushings.

If this doesn't help and since you said the rear. I would install a rear "axle side" track bar bracket to raise the roll axis. A track bar bracket will also center the axle better under the jeep.
You want to raise the track bar min 3" which most brackets will get you. Remove the frame side upper bracket and toss in the trash.
Teraflex makes a nice axle side bracket

3-3.5" of lift is a lot w/ just coils and shocks and why kits like that are cheap. Yea ... The quality is not as good as others, for the most part it's missing parts.

This should fix you up. Next I would be looking at a front track bar to center the front axle (again, at 3" it's going to be shifted 1/2" or so)
Then front lower control arms or AEV/Rancho drop brackets to bring caster closer to spec.

Good luck, any questions just ask.

I dont know if your tires are brand new as well but I put a set of terras on my Cummins and it felt like it was on marbles for the first 500 miles. New tires have those little rubber tits on them and the terras are really soft tread compound. Until you wear off those tits and get the tires broke in they are very loose feeling. I honestly thought something was wrong with my truck the day I had them installed.I took it back to have it checked. Once I got tires broke in it felt normal again.Also check tires psi and lower to something reasonable.Odds are they inflated them to max psi.

Thanks for the replys. The psi was over 50 in the tires so I dropped them down to 40 and it made a huge difference. I have already began the process of ordering some "extras" to replace some of the RC stuff

Yeah, I betting that kind of tire pressure is what was causing it.

Damn ... I guess I just "assume" folks know the psi in the tires
For a 33" 40 is still a bit high.

Yep I figured it was the tires when I read terra grapplers. I run my Duratracs at 30 psi but that might be a bit low for those tires.The chalk method is the best way.The terras are good tires once you get them broke in and psi set right. They handle great in the mud and do ok in the rain and not bad in the snow.They just dont seem to last long.
