Installed Wulf shackles. Used top holes. Perfect fit and truck sits level now. 22's next.f1cc222a70584774d0c9db9225bc0710.jpg97ee7e348b18ff3a0e38dd0ec9633d08.jpg

Looks good . Spinning the shim does clear the vib. I like the looks of dropping the rear to level than raising the front.

Got mine in today. Tried to install them on the higher set of holes and found that I still had about 3/4" of rake so I went ahead and went with the lower set. Also flipped around the shims just to be

Did you have any vibration after the shackle install? I had a little during deceleration around 20 to 30 mph. I ended up spinning the factory pinion angle shim from the thick end of the shim facing the front of the truck to the rear of the truck.

Haven't experienced any vibration.  Shouldn't have to change the pinion angle with just a shackle drop. I can understand a 4" or 5" rear drop. Did the shim reversal help?

I thought the same thing but once I did some research it's fairly common on the older body style. It kind of makes since. On a flip kit the rear stays at the exact same angle as before the flip. With a shackle and hanger style lowering kit the front and the rear of the springs are lifted together. Doing just a shackle just lifts the rear of the spring causing the pinion to point down. I'm sure it might not affect some trucks but could others. Heck I dont know if all the 19s have a factory installed shim like mine does. It might depend truck to truck. Flipping the shim did correct my minor vibration.

Gotcha.  Where's the shim at?  Where the lift block was between the axle and leaf springs?

OK thanks.  Did you have to loosen the bolt going through the leaf's or did it spin freely?  I still haven't noticed vibration but if I do I'll reverse the shim.

I'm having a vibration when slowing down. It's the worst at 30mph. I guess I'll try and rotate the factory shim. Never had a problem on my previous trucks.

Yea I hear ya.  I've never had problems in the past and have put drop shackles on many trucks.  I didn't notice any vib when I installed my shackles but then later noticed the same vibration when slowing down around 30mph.  I rotated the shim and "voila"!  Cleared it up.

Installed those 2”  dropshackles and used the 1.5” hole. Also did airbags to stop the porpoising I was experiencing while pulling a travel trailer at highway speeds over dips. I ride it 1/2” higher than flat with around 10lbs in the bags and around 20lbs with the trailer hooked up and loaded down.

19trailbossRic, what brand shackles are those? Are they the ones currently on Amazon? (Black with red bushings)

 

I'm looking to go this exact route with mine, towing a car though.

I don't want to raise the front, just drop the rear level for daily driver mode.

I figured this setup would be the best solution for both daily driving and towing.

Thanks in advance.

You might consider stock ride height bags. I got the ones for the trail boss (2' lift) and with the drop shackle they are a bit compressed and hit the internal bump stop when flat over bumps which is why I run them with air which adds an inch of rake for a smooth ride. I did the bags first for trailering but then wanted to fix the non-trailering ride height.  Also, the "trail boss" bags actually required a 1/2" shim to make them work on the factory bump stop bracket to accommodate the total axle drop once you release the loading while on the lift.

I did this on my 03 Denali and my 14 SLT,  what I noticed is it made the front of the truck seem higher at first, back goes down front goes up. I liked it and people noticed it but weren’t sure what was different. Put 305/50/20’s on the Denali looked fantastic.

      Tire psi

      By Chuck FB · Posted

      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.

      Tire psi

      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

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.
