Hello, I currently have a 2018 Silverado 1500 with a RC 2" leveling kit. I am wanting to replace the OEM front and rear shocks with the Bilstein 5100 shocks. I an not looking to raise the truck in the front or rear at all. I am happy with how it sits now. Am I able to install these Bilstein shocks with the current leveling kit on it? I know these Bilstein 5100 shocks have the capability to raise the truck in the front and rear but would I be able to just set them at the stock height and retain the current stance? Thanks in advance

Hey guys, I have a 2018 Silverado 1500. I currently have a 2" Rough Country leveling kit installed on it. I want to replace my stock shocks and struts with the Bilstein 5100's. Given the truck is already leveled will I be able to install the Bilstein 5100 struts along with the leveling kit given the bilstein's already have the ability to level the truck out without any issues? What setting will I need to run the struts on if they will work out? Im not looking to raise the truck up anymore than it already is. Thanks in advance!

I haven't thought of this, I have thought about purchasing the range technology device that plugs into the obd port but have held off. I just took it to my local dealer since the truck still has a substantial amount of warranty left on it. They said since my particular truck has the 5.3L with the 6 speed tranny it is very unlikely it is the torque converter, it is more common with the 8 speed trannys. The are going to replace the entire exhaust from engine manifold on back. They claim there is a valve/flap in the exhaust that might get stuck and cause this shudder/vibration at these speeds. Since its free I guess I don't really care but I'm definitely doubtful this will fix it. The next possible solution sounds like a fluid flush of the tranny and replacing it with something different.

What setting/notch do you have the Bilstein shocks on with the 2" leveling kit? Any issues with having both the leveling kit and Bilsteins on the truck? Just purchased a 2" RC leveling kit and want to do Bilstein 5100's as well. Thanks in advance!

I looked heavily into the 2.5" as well but dont want the extra stress on the suspension components etc. I also like the little bit of rake the 2" has. Ive been looking at 275/65/20 with the stock rims as I really like the looks of them as well. Im also purchasing bilstein 5100 shocks and struts to replace the stock ones. I will definitely post pics after I get everything installed, I appreciate the feedback! Off topic but does your silverado have the 5.3L with the 6 speed? If so I have a few questions regarding some mechanical issues ive been having with mine and would like to see if other owners are having similar issues. I can send a direct message too so I don't mess up this thread with off topic questions if that's cool with you. Thanks!

Appreciate the response! That crossed my mind as well. It only happens around 80 mph and the vibration in the steering wheel is minimal but noticeable, nothing as severe as a rumble strip vibration. It could be just the start and continue to worsen as time goes on and it is the TC which would be on GM to replace under warranty I guess.

Hello, was the dealer able to resolve this issue? I’m having the same issue on my 2018 5.3 at around 80 mph. Thanks!

Hello, I'm not sure if this is the right thread to post this to but ill give it a shot. I have a 2018 silverado 5.3L with the 6-speed transmission. The truck only has about 16,000 miles on it and is still under warranty. The problem just recently started within the last few thousand miles or so but when traveling on the interstate between 78-82 mph (Yes, very specific speed) and goes into v4 mode the truck makes a constant shuddering noise (not sure what else to call it) and there is a slight vibration in the steering wheel but goes away once it goes back into v8. Its honestly not that bad but it doesn't do it at any other speeds when in v4 and can get annoying when traveling long distances on the interstate. Once back into v8 its totally fine and smooth. I know the range afm disabler fixes this and I will likely purchase this in the future but would like to see if there is a factory fix the dealer can do since the truck still is under warranty and has low miles. Id like to see if anyone else had this issue and if it was fixed by their dealer. I have cruised at other speeds from under 75 mph and over 85 mph and it doesn't do it which I find weird as most people on here experience it at a variety of speeds. Thanks!

How have you liked the 2" rough country kit long term? Any issues/complaints? I have same truck color and all and was thinking about the RC 2" leveling kit and Nitto Terra Grapplers but I haven't pulled the trigger yet. Thanks!

I have seen many other threads with this similar issue but different circumstances so I thought id post mine to see if gm has found a fix. I have a 2018 silverado 5.3L with the 6-speed transmission. The truck only has about 16,000 miles on it and is still under warranty. The problem just recently started within the last few thousand miles or so but when traveling on the interstate between 78-82 mph and goes into v4 mode the truck makes a shuddering noise (not sure what else to call it) and there is a slight vibration in the steering wheel. Its honestly not that bad but it doesn't do it at any other speeds when in v4. Once back into v8 its totally fine and smooth. It doesn't do this at any other speeds just that range. I know the range afm disabler fixes this and I will likely purchase this in the future but would like to see if there is a fix the dealer can do since the truck still is under warranty and has low miles. Id like to see if anyone else had this issue and if it was fixed by the dealer. I live in Nebraska and have taken all my GM trucks to Sid Dillon Chevrolet and they have always been great to work with and have gone above and beyond to fix problems but Id like some more information from other owners before I take it in and complain. Thanks!
