I think each truck can be different. My 2WD RCSB with 2" drop shackles needed 2° pinion shims to eliminate a 20-30 mph vibration. With the shims, the vibration is gone and the truck drives very smoothly.

I agree, plus if you have a CC standard bed like me, you have to deal with the two piece drive shaft. From what Ive read this configuration almost always need an adjustable carrier bearing installed.

Does anyone happen to have a picture of the stock shackles? I bought my truck used and I'm pretty sure the guy before me put some drop shackles on it. I only have about 1.25-1.5''" of rake, while most are around 3'' from factory. That would put it around 1.5'' drop shackle, and the only company I am aware of that makes that size is Rough Country. From what I remember when looking under the truck, it has the same design as the Rough Country shackles, but I am offshore and not able to look at them right now. I am going to take the factory block out when I get back home to finish leveling it out.

Here's the stock shackle on a 2016 2wd:

The mcgaughys I got are a fair bit larger than this, I'm actually concerned I ordered the wrong thing now.

 

My main concern right now is that my 2015 has been in the shop 4 days with a bad diff, and I'm worried that if I put this on, they will tell me my wrranty is void or that my shackles are causing the issues if the problem persists.

 

But at the same time.. I dont want to look at my "slamming on brakes ALL THE TIME" profile when I'm walking to it from a parking lot.

Awesome thanks for the photo. I'm sure the 2015 and 2016 would have the same shackle. This confirms I do have something aftermarket because my shackles are different. And yes, the drop shackle will be longer than the factory shackle. I would document the issues you are having with just the stock shackle in place with time stamped photos or something. Then if you had the same issue down the road after swapping to the drop shackles you could make a case. Not saying that would save you, but it might help. I would get the diff issue fixed first and ride it for a week or so before dropping it. Thanks again

What tire size would be the biggest you can get without scrubbing if you drop the back with 2 inch shackles? I plan on eventually upgrading to 20" rims and michelin ltx tires. Just need to know what size tires to get without rubbing.

You will be fine. pull a tape measure and subtract 2" from current stance. I have 305-45-22 with no scrubbing.

hi there I am new to the forum. I have a 2015 denali. I have the rear 2" levelling kit from mcgaughy's. I am wondering if anyone who has done it before can shed some light on what I have to do with the sensor arms ? They told me they might not be building the correct length arms for a while. I have had some people tell me that it can't be done and others tell me it can but you have to cut the sensor arms. If anyone has any knowledge on this please let me know. Thanks

2014 4x4 with aluminum front suspension. I used DJM 4" control arms and made a spacer to bring it up to 3.5 in front then done a 5/6 flip kit set at 5" no rubbing binding or vibrations tires are 285/45/22.

Got any pics of yours after dropping the rear? I plan on doing the same and curious how it looks with just the 2" shackles and blocks still in?

 

Thanks!

LOL.... It is still hiked up in the ass! If you want close to level remove the block and add shackles. Read the post's on this!!!

Here's a quick pic taken at work. I like the look of the 2" drop: there is still a slight rake but nowhere near as noticeable as before.

    • Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol    
    • You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !
    • This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.  
    • My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
