2014+ Lowering / Drop Kits

Bushx · July 21, 2015

Pick up my new to me '14 cc, short box Sierra tomorrow. Got the dealer to include a set of 18" gloss black chev rims with new Duratrac tires in stock size for the 18's. Truck is Iridium. Think it'll look good. I read this entire thread and think I've decided to buck the local trend. Just about everyone and their dog has a lifted or levelled truck with oversize tires. Even me, my last ride was a lifted xterra on 33's. Going to try just removing the blocks on the rear of my Sierra to keep a little rake as I'll often be carrying 250 to 500 lbs of dirt bike(s) in the rear. Just unsure how it'll look with the aggressive Duratrac tires. Don't mind the aggressive tires, as camping and just getting the bikes to the trail will see me on gravel and sometimes muddy roads. And they're great in winter. I'll post up a pic if I decide to go ahead with it. Googling for lowered truck and aggressive tires didn't get me much lol.

I'm getting 36" front and 37 1/2 rear. But I'm thinking of putting it back to stock. I'm getting vibration and noises from the back after the skackles was install. Looks good but not worth it.

I like the sounds of those measurements, but I agree not worth it if you're getting vibrations... How about putting the shackles back to stock and pulling the rear block instead?

I have the stupid magnetic ride control. I there are sensor bolted onto the blocks,so it can not be removed. But it was riding great stock. With a few hundred pounds in the back it rides even better.

I am getting the 2" McGaughys shackles, I've read nothing but good things about their products.

If you have a 2015 with magnetic suspension then I would reconsider.

Sorry guys, I have read this whole thread and I'm still confused. I am looking to lower my 15 4wd Denali and was wondering if it is possible? I would love a 3/5 drop but would settle for a 2/4? I haven't seen a lowered Denali on here yet. Any help is appreciated. Thanks!

I've dropped mine 2/4 with McGaughys. Getting a stabilitrak light keep coming on at slow speed turns in side streets and parking lots. Not worth the hassle until I can figure it out. Had the BCM reset today at GM. Not fixed. ???

I had the same issue intermittently a few times. Just like you, only at slow speed (maybe 2-5 mph). A few times Ive felt the brakes pulsate like I was losing traction. I have no idea whats caused it. I have a 2/3 drop though and it hasnt happened in a month.

I'm looking for help in regards to my Stabilitrak. I lowered my 2015 Denali 1500 2/4 with McGaughys kit. It's got Magnetic suspension with those little level control boxes. We bent the rods in the rear to match the factory angle like the kit said to do. Mr. McGaughy and staff won't answer calls or return messages so here I am. At about around 5-20 mph turns on side streets or parking lots the Stabilitrak light will flicker a few times and cut throttle until I straighten out again. I have 24" wheels on the vehicle. Just had a wheel alignment. GM just reset my BCM (body control module) today as well and it's still not fixed. Any help would be wonderful. Sorry for the double post. This one has better info. Thanks!!

Removed block and 1 inch hole on the drop shackles

Installed the 4"/7" Belltech kit today. Spindles, Street Performance struts and upper control arm offset bushings in the front. Flip kit and Street Performance shocks in the rear. Perfect alignment with still some camber adjustment to spare. Rides really nice although the rear shocks are a tad stiff. No vibrations or issues of any kind.

I'm wondering if anyone on this site can provide some insight. I currently have rancho quicklifts that give me 2" of lift. They are a complete strut assembly that is slightly longer than stock and also raises the spring perch similar to bilstein 5100's. You're probably wondering why I'm talking about lift struts on a lowering thread, but here it goes.

I'm considering using 1" lowering coils to drop my truck down to 1" of lift instead of 2" of lift. The rancho quicklifts that I have use an OEM spring and I find they're too stiff and I assume its from the way they raised the spring perch, which in turn compresses the coil.

I'm hoping there are some 1" lowering coils that have either the same spring rate or an even lower spring rate than stock. If it was lower I could increase my adjustable damping on these shocks to compensate.

So my question is.. Does anyone know if there are any 1" lowering coils that are just as good if not better riding than stock coils?

Looks great! I was thinking of doing the same thing. Did you run into any problems with the seam on the bottom side bed only using the 1" hole on the shackle? Any problems at all with that setup?

Thanks! No problems with it, rides just like stock. I did bend the seem on the driver side but it was more for ease of access to putting the shackle in.

Do you think it could be done by loosening the bed bolts and lifting it a little. My bed is slightly off set anyway so I could even it out while I did the rear suspension.

You probably don't even have to bend the seem, it'll just take a little finessing lol I just got tired of struggling with the long bolt in the awkward position and trying to get it in.
