Citumo 2" Rear Drop Shackles for Chevy GMC Silverado Sierra - 1–2" Lowering, Heavy-Duty Steel

Citumo upgraded 2-inch rear drop shackles are heavy-duty replacement shackles that lower compatible Chevy/GMC trucks by 1–2 inches for a cleaner stance without cutting springs.

If you want a reliable, bolt-on way to lower the rear of your Silverado, Sierra or earlier C/K trucks without altering the leaf springs, these Citumo shackles are designed specifically for that job. Machined from durable steel with factory-matching mounting points, they bolt in where the original shackles sit and deliver a controlled 1–2" drop to improve stance and rake while keeping installation straightforward for DIYers and shops.

Will these shackles fit my truck?

These rear drop shackles are made to directly replace the factory lower shackles on many Chevy and GMC trucks. They fit several generations and key models; confirm years and part numbers before purchase to ensure a perfect match.

• Compatible models: Silverado/Sierra 1500 (1999–2019)
• Also fits C1500/C2500 and K1500/K2500 (1988–1999) and Suburban versions listed
• Direct replacement for part number 410520
• Check existing shackle geometry and bolt sizes for verification

How much will my truck drop, and how does it affect ride?

Citumo shackles are engineered to lower the rear axle by approximately 1–2 inches depending on shackle orientation and your truck's original suspension geometry. This modest drop improves the visual balance between front and rear; ride characteristics remain similar since the leaf springs and shock mounts are unchanged.

• Typical drop range: 1" or 2" depending on shackle position
• Maintains original leaf springs and shock locations for predictable handling
• Does not require cutting or permanent modification of springs
• May require minor alignment or pinion angle check after installation

What are these shackles made from and how durable are they?

Citumo uses robust steel construction and precision welding to ensure long service life under road and load conditions. The design resists bending and fatigue from repeated load cycles while protecting the frame-to-axle connection that carries rear cargo and towing loads.

• Heavy-gauge steel construction for strength and durability
• Welded and finished to resist corrosion and wear
• Engineered to handle normal payload and towing loads when used as intended
• Backed by a 12-month warranty for parts confidence

How easy is installation and what hardware is included?

Installation is a straightforward swap of the factory lower shackles: unbolt the original shackle, position the Citumo unit, and secure with supplied or existing hardware. Basic tools and standard mechanical experience are sufficient, though professional installation is recommended if you’re unfamiliar with suspension work.

• Direct bolt-in replacement—matches factory mounting points
• Uses existing frame bolts or supplied replacement hardware where applicable
• Recommended tools: jack, stands, socket set, torque wrench
• Quick install time for experienced mechanics; allow extra time to check pinion angle and torque specs

Who is this for: The Citumo 2" Rear Drop Shackles are ideal for truck owners who want a safe, reversible way to lower the rear of Chevrolet and GMC pickup trucks for improved stance without cutting springs or extensive suspension modification. They suit DIY enthusiasts, aftermarket installers, and anyone maintaining or refreshing older trucks needing a direct replacement shackle with a controlled drop and durable construction.
