How is your GC driving after the 5100s? Any flighty feeling? Light steering?
Amazing, I took my sway bars off too and now I have more travel than all the guys with quadralift. Don't get an alignment at the same time, you'll want to let your suspension settle for a day or two and cycle your struts if you can. You will waist your money if you get an alignment at the same time because I lost .5" of hight after a day or two so you should deffinetly wait. I set mine at 1.25" of ride height and went home and measured it and realized I got 1.75" and my front was higher than my back. I was not happy, but then it leveled out after doing a little off roading and cycling my shocks, or sitting over night. I'm not sure exactly what did it but I definitely lost .5"

Re: 275/55 20 All Terrain Tire Thread

I almost forgot to mention, If you have bigger tires with the bilsteins your jack won't be tall enough to change a tire Mainly because the Bilsteins will give you 2" more droop travel. This may not be true if you keep your sway bars on I don't know, but you might want to check it. I carry around two pieces of wood to put under the jack so I get enough lift.

Thanks for the tips. I'm pretty handy with cars. I should be able to install the struts myself. I just didn't want to mess with spring compressors. I will post photos and first impressions once I'm done.

The WK2 is difficult to work on. The machine that compressed springs wouldn't even work, they had to take the struts to another shop to have it done. They also took the lower control arm off the vehicle just to get the strut out although I think it can be removed by taking off the broke calipers. I watched the hole thing, it took 3-3.5 hours to do two struts and the rear shocks. I got it done for $250.

I don't know if you off road or have bigger tires but I've been considering putting the OME rear shocks on because they are longer and would give more droop travel and articulation but would bottom out easier if not installed with the 2" lift springs they were designed for. I have issues with my tire hitting the wheel well anywys and longer shocks would probably stop that. Good luck, look forward to hearing about your results.

Sounds like it's a better idea to pay a shop to do it.

I'm also considering converting the GC SD brakes to heavy duty brakes. I'm looking at Powerstop Z23 front 350 mm rotors (AR83078XPR), pads (Z23-1455) and Mopar caliper brackets (68052372AA). Powerstop also has slotted and drilled solid rear rotors for those of us that do not have HD brakes from the factory which have vented rear rotors. Total without the rear rotors and pads is around $256.

I've been looking all over for something like that and couldn't find anything.

Will you provide the details on that spacer kit, I'm definitely interested.
The TJ spacers are only for the rear springs.

I installed the front level kit from RRO and felt that the back was too low.
So then installed the TJ spacers on the rear springs. They install on top of the spring on top of the spring isolator between the isolator and the body.

There is a video, no a real good one, but on youtube there is a guy that installed the TJ spacers.

I hope this helps.

Can you tell us the manufacturer for the spacers you used?

Re: 275/55 20 All Terrain Tire Thread

Well, the tires (Kumho Road Venture AT51) are installed. I checked for clearance and turned the wheels lock to lock and no rubbing. I will find out if they rub once I go off-roading (nothing crazy).

I noticed the tires are pretty quiet considering the how aggressive the tread is compared to stock Forteras. The tires looked huge before mounting. No balancing issues at all.

Re: 275/55 20 All Terrain Tire Thread

Just drove the GC on the highway, no difference in tire noise. Checked my speed with my iPhone and car GPS. At 70 constant on the iPhone the car is doing a little over 68. So 2 mph faster than what the speedo reads.

Re: 275/55 20 All Terrain Tire Thread

Quick update:

I had the Bilstein 5100s installed today. My first impressions are good. Less nose dive when braking and the ride is pretty smooth. I had them set the shocks at the 1.25 inch mark bringing the front just shy of .5 inches lower than the back. The stance is much better and looks level even though the back is slightly higher.

One thing, I noticed and I would like to know if anyone has experienced this:

The vehicle is not level from side to side in the front. Both of the rear fender flairs sit at 35.5 inches. The left front sits at 35" and the front right sits at 35 3/8. Before the 5100s the same issue was there albeit at a lower height.

Any ideas why this is?

Re: 275/55 20 All Terrain Tire Thread

Just a quick update regarding gas mileage after the new tires. I went through one tank of gas and gas mileage is well within the usual average. For the last year I've averaged 19.22 MPG. On my first tank of gas after new tires I averaged 19.4.

The only thing I did different was I tried to maintain my RPMS within the Eco green zone as much as I could but not hypermiling.

I was surprised as I was expecting a significant drop in MPG. GO figure.
