I agree, but in my case the bushings were apparently shot. So when I replaced the upper control arms I did drive the truck that day and the next before putting the new tires on. I think the ride soften in that it didn't clunk at every bump anymore. It was silent once again!

They look amazing! Like others have said before me, these are the perfect size for our trucks! A little bad news and bump in the road though, I have a lot of shaking going on in the rear end now. I pulled the road force numbers from the shop I use. 16, 30, 32, and 36lbs of road force in the tires. The higher of the two are in the back right now. The shop is great, and they use the Hunter GSP9700 and calibrate often. I know my wheels are round, so it's the tires for sure. Now for the good news! I called Nitto and spoke with Jose, he was great! After inquiring as to what truck, wheels and tires I have, he said they are going to replace the 3 tires with high road force for me! Said they should be down near or below 20. Called the shop and they are calling in to give the info Nitto requires and make this change for me. I know we often only get to read about the bad customer service from companies out there, but we need to make sure we hear some of the good as well! Nitto stepped up, and it's much appreciated!!! Looking forward to getting the replacement tires soon and riding smooth and looking good!!! I will try and get you pictures by this weekend!

Yes sir! Love the Ridge Grapplers! Amazing how quiet they are. I know they are new but still was expecting a lot more noise from them. Ride is fantastic. So Happy with both the tires and upper control arms!

I installed the cognito upper control arms and man what a difference! The popping sound is gone, and the entire front end feels softer on bumps and quieter. Apparently I had more issues with the bushings than I thought. I guess we just get used to things over time and don't realize it.

Thanks again BigWhiskey! I did the 1" crank for the torsion bars in the front two weeks ago. Noticed no difference in ride. I had been tracking down a popping/clunk noise in the front and finally found it to be the driver's side upper control arm bushing. So Sunday I put on new Cognito upper control arms. Well apparently I had more noises than I new up there! The ride is so much quieter and softer up front. Very noticeable on speed bumps! Very happy I did the new arms for sure! I got the new tires on today and man are they quiet for being so aggressive looking! I went with 285/75R17 Nitto Ridge Grapplers. No rubbing anywhere and I doubt I will get any off road with the 1" cranked up front. Granted they are new, but seriously these things are almost silent. So happy with the look, feel like I got a new truck!!@ thanks for all the info and PM's from you!!

Great thread here folks! Tightened my front cross member and got rid of most of the noise I was hearing. Now I only get a clunk/pop on the dirvers side when turning into my driveway and some times when going over a speed bump while turning slightly. Any ideas? I am going to tighten the control arms, is that as easy as just tightening them up? I don't want to screw anything else up while attacking this problem.

Love your build thread bud! I myself have a 2015 white crew lt with Duramax. Going with Nitto Ridge Grapplers on my stock 17" wheels the end of this month. Was going to go with 285/70r17 but then found your build thread! So nice to find someone with the stock 17" wheels! Most don't know they exsist! So I know you said they don't rub at stock height, but do you think they will rub off road on forestry roads and hunting grounds? No rock climbing here or high speed off road use. Hoping you say they will be fine at stock height, but I did already replace my shocks with Bilstein and the fronts are good for up to 1 1/2" of lift. Don't really want to crank the bars but if I did 2-4 turns for 1/2"- 1" will I notice a worse ride? Thanks guys!!
