1 Inch Rear Drop | 88-18 Silverado-Sierra 2WD 4WD |

The 1-inch rear drop shackle kit for 1988–2018 Silverado / Sierra 1500 (2WD & 4WD) gives you a subtle but effective way to lower the back end of your truck. By replacing factory rear leaf spring shackles with shorter units, this kit lowers the rear approximately one inch, producing a more balanced or level stance when paired with other suspension changes.

Constructed from heavy-duty steel and finished with corrosion-resistant powder coating, these shackles are built for durability under load and harsh weather conditions. The design maintains the use of factory leaf springs and most of the original geometry — making this a lower-risk modification compared to full drop kits or aggressive suspension overhauls.

Installation is straightforward: bolt-on replacement of existing shackles, with no cutting or welding required.

For truck owners who want a modest drop to even out stance or lower the rear slightly for aesthetics, this 1″ drop shackle solution is a clean, dependable option. Since the change is modest, it avoids many of the issues of aggressive drops (binding, shock travel, geometry stress) — making it a smart pick for daily-driven and show trucks alike.
