What is Hyper-Flex polyurethane?

Hyper-Flex is a proprietary performance polyurethane material developed by Energy Suspension. It's known for its strength and longevity, designed to last significantly longer than standard rubber components in suspension applications.

How do these shackles improve vehicle control?

By replacing worn or degraded rubber bushings with a more rigid and durable polyurethane material, these shackles help reduce unwanted flex in the suspension. This leads to more direct steering response and better stability during maneuvers like cornering and braking.

Are these shackles a direct replacement for the original parts?

Yes, these front spring shackles are designed as a direct replacement for your stock components. They are intended to fit the frame shackle locations on the specified Ford F-250 models without requiring modifications.
