Product Description

The ICON 91001 1" Rear Lowering Shackle Kit is designed to fine-tune rear ride height on **2010-2025 Ford F-150, F-250, and F-350 Super Duty** trucks. Manufactured from durable CNC-machined aircraft-grade aluminum, these billet shackles provide approximately **1 inch of rear drop**, helping achieve a more level stance with less front lift required - or assisting in rear suspension tuning when using aftermarket leaf springs. Its gusseted design ensures proper bushing clearance and helps maintain suspension articulation even under load.

Pre-installed OE Ford bonded bushings are replaceable and maintenance-free, offering smooth, quiet operation throughout full suspension travel. The satin gray anodized finish resists corrosion, making this kit suitable for daily driving, towing, or off-road use. Easy bolt-on installation means no welding or cutting of frame or suspension components, and the kit works with both stock leaf springs and most aftermarket spring packs, giving you a simple way to fine-tune your truck's rear ride height and stance.
