Questions on 2 inch drop shackles for my truck

Question

I have decided to try dropping the rear of my new to me 2013 Chevy Silverado 2500 HD LTZ. I either have to raise my 5th wheel or lower my truck in order to tow level and to obtain more clearance between truck and 5th wheel. I do not haul heavy loads in the truck other than a load of mulch maybe once a year. It was purchased with the intent of pulling my 5th wheel now and any new 5th wheel in the future.

I was researching what is involved and it seems the most difficult portion of this is removing my hitch to install these shackles.

Now my question is what brand to purchase? I have found prices at Auto Zone at $30 bucks or so up to $150.

Two name brands that came up are Belltech and Mcgaughys.

I have no clue what brand or if the no name brand from Auto Zone are good and SAFE. I'm not against paying for what is best but I also do not want to pay for what is not needed. Safety first please!

Thanks in advance for your help!

Dave

We had the 1st bell tech longer rear shackles made for our 2001 3500 2wd chev. I was after GM for several months before they asked Bell tech to build something.

I still have the original shackles and no reason to keep them because we don't have that truck now. We had the chev store install ours. A little shudder on take off if you hit it hard but a normal take off it didn't . Not a problem at any time for us. Our 05 came the same rear height as the 2001 after it was lowered.

I bought my 4 inchshackles from J.C. Whitney; I do not recall the price I paid but I thought it was reasonable. I did not have to remove my hitch to install them.  The only problem was the shackle bolts were installed backwards, i.e. the bolt heads were closer to the inside of the bed and could not be removed with out cutting some metal from the bed seam.  I suspect that the bolts were installed in that direction to ensure that they would be retained if the nuts worked their way off.  When I replaced the bolts, I installed the nuts inboard, much easier that way.  I do check them each time I change the oil. I guess the professional way to secure them would be to drill the nuts and safety wire them, but this ain't aircraft maintenance any more.  Check my truck description in my sig.

Anyone else have an opinion on 2 3 or 4 inch shackles?Thanks!Dave

Little confused in what all you are attempting to accomplish.

You want to tow level. Is the trailer high? What change in height will level the trailer?

You want to increase clearance. How much clearance are you wanting to add? Drop the pinbox by this amount.

Add these two amounts together for total suspension adjustment.

You will need to realign your headlights since the truck will probably ride nose high.

Drop the pinbox by this amount.Add these two amounts together for total suspension adjustment.You will need to realign your headlights since the truck will probably ride nose high.I have between 31/2 and 4 inches of clearance between truck side rail and 5th wheel right now. I want to get 6 or more inches. This truck is high in the rear end. I could drop it 2 to 3 inches and then it would be level. My pin box is already at the lowest setting and my hitch is at the highest. I know that regardless of the bed clearance my 5th wheel will be riding nose high.
