This lowering shackle set will fit any GMC or Chevy 2500HD Pick up truck from 2011-2021 gas or diesel.
For the 2020-2021’s we highly suggest looking at our other listing for the 3/4” drop shackles specifically for those trucks! The 1.4" shackle requires a small ear to be trimmed off the pinch weld on any 2020-2021.
These can be used on the 3500HD single wheel or dual rear wheel application as they share the same shackle. The difference between the 2500 and 3500 is, the 3500 has a set of helper springs stacked on top of the traditional 2500 leaf pack. These helper springs have a separate bump stop and when you lower the rear of the truck, it reduces the gap between the helper springs and bump stops, which leads to them gently resting against each other. This will not harm anything as they are designed to do so. However, you will experience a slightly firmer ride in the rear!
They will not work on the 1500 Pickup unfortunately.
They have been designed specifically for people who want to lower the rear of the truck without having to modify the pinch weld or bed seam! **These are 100% drop in, no modifications required to the truck!**  It will lower the rear 1.4”. Anything over 1.5" would require bending, cutting or hammering of the bed seam since it would interfere with the top of the leaf pack which could potentially create cancerous rust or structural integrity.  The purpose is to allow the maximum amount of drop in the rear, and not have to make any modifications to the vehicle. It truly utilizes the full amount of space between the top of the leaf pack and the bottom of the bed.  A great alternative to expensive leveling and lift kits!
As seen in the pictures, all trucks have reduced rake by lowering the rear 1.4" and raising the torsion bars roughly 1".  **(Please keep in mind, it is completely up to you if you want to raise your front end.)** This will not effect ride quality at all and makes the truck look much better without the ridiculous rake that the factory height provides. Customers using these shackles with tires as large as 35" on factory wheels but anywhere from 32"-34" tires are ideal.
Also, if you have airbags in the rear, these will accommodate each other very nicely while towing heavy! Please note - The airbag kit must not use an internal jounce stop. Usually Airlift or Firestone riderite kits is what we recommend.
These are made much stronger than the factory shackles and have a thicker metal material used for heavy duty use and longevity. They have a powder coat satin finish for a long and durable life to prevent rusting in those harsh winter environments!!!! The bushings are rubber encased and pressed in. Meaning it's a one piece, that has a rubber outside and a metal tube inside for the bolt. **Same type of rubber durometer you would find on factory.** This feature is key when maintaining a smooth ride and durability. The materials used, and bushings in these are far superior than what comes in most aftermarket shackles. That is why this shackle is considered a "premium shackle" and separates itself from the rest.
They are hand crafted and made right here in Pennsylvania
Installation is roughly two hours and can be done in your driveway.  **
