Dorman Rearward Leaf Spring Shackle for Chevrolet & GMC Trucks 1999–2013 — Powder-Coated Steel, Hardware Included

Dorman 722-029 is a heavy-duty rearward leaf spring shackle built as a direct replacement for worn or corroded factory shackles on compatible Chevrolet and GMC trucks.

If your truck shows symptoms like sagging rear ride height, uneven tire wear, or clunking from the rear suspension, a fatigued leaf spring shackle can be the cause. This Dorman shackle is made from robust steel and finished with a corrosion-resistant powder coat so it resists rust and restores the intended leaf-spring geometry. It ships with the hardware needed for installation and is designed to match the original equipment form, fit, and function.

Will this shackle fit my Chevrolet or GMC truck?

Compatibility is vehicle-specific across many model years and trims. The part fits numerous Chevrolet Silverado, Suburban, Avalanche and GMC Sierra and Yukon XL 2500 models listed for the 1999–2013 range; verify your exact trim and year using the vehicle garage tool before ordering.

• Fits many Chevrolet Silverado 1500/2500/2500HD and Suburban 2500 years 1999–2013 (see fitment list).
• Compatible with GMC Sierra 1500/2500 and Yukon XL 2500 across multiple years.
• Use the Confirmed Fit bar and the garage tool to confirm exact fitment for your vehicle trim.

How does this part improve rear suspension performance?

Replacing a worn shackle restores the correct mounting angle and travel for the leaf spring pack, reducing unwanted movement and noise. That helps return ride height, stabilizes load handling, and prevents accelerated wear on adjacent suspension components.

• Reestablishes correct leaf spring alignment and travel.
• Reduces clunks, rattles, and rear-end sway caused by loose shackles.
• Helps prevent uneven tire wear and extra stress on bushings and springs.

What materials and finish protect this shackle from corrosion?

The Dorman shackle is constructed from durable stamped or formed steel engineered to withstand towing and hauling loads. A powder-coated finish covers the steel to provide a barrier against moisture and road debris, extending service life in harsh environments.

• Heavy-gauge steel body resists bending under load.
• Powder coat finish fights rust and surface corrosion.
• Supplied hardware is selected to match installation needs and longevity.

How easy is installation and what comes in the box?

Installation is straightforward for anyone comfortable with basic suspension work and common hand tools; it typically involves removing the old shackle, transferring or replacing bushings if needed, and bolting the new shackle into place. Dorman includes essential mounting hardware so you won’t need to source bolts or bushings separately for most installations.

• Comes with the required mounting hardware for a quick swap.
• Designed as a direct replacement to match original mounting points.
• Recommended that bolts be torqued to manufacturer specs during install.

It’s well suited to do-it-yourself mechanics, fleet maintenance teams, and anyone restoring proper rear suspension geometry after years of use or heavy towing.
