ATRACYPART Lowering Shackle Kit for Silverado 1500 — 2–3 inch Rear Drop, Coated Steel Durability

ATRACYPART Lowering Shackle Kit delivers a safe, reversible 2–3 inch rear drop for compatible trucks to achieve a lower stance while retaining the factory suspension.

This heavy‑duty lowering shackle kit is built to let owners of Silverado, Sierra, Chevy/GMC C/K models, select Ford F‑150s and Rangers lower the rear of the truck without swapping springs or changing the OEM suspension geometry. The kit includes a pair of drop shackles and gaskets, is made from coated steel for corrosion resistance, and is designed as a direct replacement for specific factory parts so installation stays straightforward for experienced DIYers and professional shops alike.

Will this kit fit my truck model and year?

The ATRACYPART kit covers a broad list of GM and Ford trucks. Check the detailed vehicle list in the product description, match the model years and cab/bed configuration, and verify the original shackle part number where possible before ordering.

• Compatible models include 1999–2019 Chevy Silverado 1500 and GMC Sierra 1500.
• Also fits many 1988–1999 C/K series, 1992–1999 Suburban/Yukon, 1995–1999 Tahoe, and select Ford F‑150 and Ranger years.
• Replaces factory numbers such as 410520 and 6400 — useful when confirming fitment.

How much drop will I get and how does it affect ride?

This shackle kit is engineered to lower the rear ride height by approximately 2 to 3 inches depending on vehicle setup and spring rate. Lowering the rear reduces center of gravity slightly and produces the lowered stance many owners want while preserving the original springs and most suspension characteristics.

• Typical reduction: 2" or 3" depending on installation orientation and chassis.
• Maintains stock leaf springs — no spring cutting or spacer kits required.
• May change load capacity and rear geometry slightly; check alignment and headlight aim after installation.

What materials and protection are used for longevity?

The shackles are fabricated from heavy‑gauge steel and finished with a corrosion‑resistant coating to withstand road salt and moisture. The kit also includes multiple gaskets for a secure fit and reduced metal‑to‑metal wear at the mounting points.

• High‑strength steel construction for durability under load.
• Protective anti‑rust coating extends service life in harsh conditions.
• Includes 8 gaskets to ensure tight mounting and minimize noise or wear.

Who is this for: The ATRACYPART Lowering Shackle Kit is aimed at truck owners who want a straightforward, reversible rear drop without replacing springs or installing a full lowering suspension. It suits enthusiasts seeking a lower stance for aesthetics or mild handling changes, owners restoring or modifying older C/K and S‑series trucks, and professional installers who need a reliable, bolt‑on replacement. If you plan to carry heavy rear cargo or tow regularly, review vehicle load ratings and consider professional advice before lowering.
