Fine tune the rear ride height on your 2010-2024 Ford F-150 with ICON Vehicle Dynamics’ Billet Aluminum Lowering Shackle Kit. CNC machined from 6061 aviation grade aluminum; these billet shackles offer increased strength compared to the thin steel of the stock units to better withstand the stresses of aggressive off-road use. Their increased length also lowers the rear ride height of the truck by 1”, requiring less front lift to achieve a level stance or to assist in rear ride height tuning with aftermarket leaf springs. Their gusseted design ensures proper bushing clearance to allow fitment for stock leaf springs, ICON F-150 Multi-Rate Leaf Springs, and most other aftermarket spring packs for a wide range of suspension setup options. Pre-installed, replaceable, press in OE Ford bonded bushings make for an easy install, require no periodic greasing, and offer noise free operation while still cycling full suspension travel. The shackles look as great as they perform with a satin gray anodized finish.
