Upgrade your Freightliner Cascadia 113 or 125 with durable, high-performance leaf spring and hanger components, like u-bolts and hardware, designed to optimize your truck's handling, stability, and comfort. Installing aftermarket leaf springs and hanger parts can enhance the support and stability of your rig by preventing excessive leaf spring movement and ensuring proper axle alignment when your tires hit the road. Not only that, upgrading your leaf spring components can lead to increased durability and better vehicle control while cornering or braking. These parts are so essential to the performance of your Freightliner Cascadia. In fact, it's why we only show parts from reputable, high-rated vendors like Premier, Automann, and BESTfit.
