WFLNHB Lowering Leaf Spring Shackles for Chevy Silverado & GMC Sierra 2007–2018 — 2–3in Rear Drop, Solid-Steel Bolt-On

These heavy-duty replacement shackles are engineered to alter rear suspension geometry safely while keeping installation straightforward. Constructed from solid steel with professional welds and a precision-formed bend, the WFLNHB shackles are coated to resist corrosion and include all high-strength mounting hardware. They’re designed as direct-fit replacements for stock shackles on compatible Silverado and Sierra models, providing a controlled 2–3 inch rear drop for improved stance and handling.

How much rear drop will I get with these shackles?

The shackles are built to produce approximately a 2–3 inch lowering of the truck’s rear. Actual drop varies by spring condition, load, and tire size, but the design targets that range without additional modification.

• Nominal drop: 2–3 inches of rear ride height reduction
• Works with factory 1/2-ton leaf springs
• Final height depends on spring sag and payload

Will these shackles fit my Chevy Silverado or GMC Sierra?

They are intended as replacements for 1/2-ton Chevy Silverado and GMC Sierra models from 2007 through 2018. Always verify your truck’s year and bed/suspension configuration before ordering to confirm compatibility.
