ATRACYPART Rear Lowering Shackle Kit for Silverado 1500 2–3" Drop — Heavy-Duty Steel, Anti-Rust Finish

This ATRACYPART Rear Lowering Shackle Kit drops the rear axle 2–3 inches to give compatible Chevy, GMC and select Ford trucks a lower stance while retaining the stock suspension.

If you want a measured, reversible way to lower the rear of your truck without changing springs, this two-piece shackle kit provides a simple bolt-in solution. Built from heavy-duty steel with an anti-rust finish, the kit includes two rear drop shackles plus gaskets and replaces common OE part numbers on many full-size pickups and SUVs. Note: installation orientation can vary by model year—verify fitment and direction for your Silverado 1500 before installing.

How much drop does the kit provide and how does it affect ride?

The shackles are engineered to lower the rear axle by approximately 2–3 inches depending on vehicle year and leaf spring orientation. This modest drop reduces rear ride height and lowers the center of gravity while keeping the factory springs in place.

• 2–3" drop range depending on model and installation direction
• Maintains stock spring rates and load-carrying characteristics
• Improves stance and can reduce squat under acceleration
• Reversible: original shackles can be reinstalled to return to factory height

What is included and what materials are used?

The package is supplied with the parts needed for a two-wheel rear drop installation and is finished to resist corrosion from road exposure. Hardware and gaskets are provided for a complete, direct-replacement installation where applicable.

• 2x rear lowering shackles and 8x gaskets included in the kit
• Constructed from heavy-duty steel for long-term strength
• Durable anti-rust coating on all steel surfaces
• Replaces common OE numbers such as 410520 and 6400 where applicable

Is installation difficult and are there important fitment notes?

Installation is generally straightforward for anyone familiar with basic suspension work, but the correct orientation can differ between model years. Verify the direction of the lowering shackle for your specific truck before final torqueing to ensure the intended drop and clearance.

• Basic hand tools and jack stands required; follow vehicle service manual torque specs
• Orientation varies by year—check alignment of shackles and leaf springs first
• Not a substitute for modified springs if more drop or different ride characteristics are desired
• Professional install recommended if you’re unsure about suspension work
