How long do these polyurethane bushings typically last compared to rubber?

Energy Suspension's Hyper-Flex polyurethane bushings are designed to last 5 to 10 times longer than conventional rubber components. This extended lifespan means less frequent replacement and more consistent performance over time.

What is the main benefit of using polyurethane leaf spring bushings?

The main benefit is improved vehicle control and suspension performance. Polyurethane is a well-built material that resists deflection better than rubber, helping to keep your suspension working as intended during acceleration, braking, and cornering.

Does this kit include all the necessary hardware for installation?

This kit includes the rear leaf spring bushings. It's always a good idea to inspect your existing hardware, such as U-bolts and nuts, to see if they need replacement during the installation process.

Product Details

When you're looking to firm up the rear suspension on your 1999-2007 Ford F-250 Super Duty, replacing worn-out rubber leaf spring bushings is a key step. These bushings are critical for allowing your suspension to move correctly while also absorbing road shock and controlling body roll. Worn bushings can lead to a mushy feel, poor handling, and even clunking noises, especially during acceleration, braking, or cornering.

This set from Energy Suspension is made from their Hyper-Flex performance polyurethane, a well-built material that's known to last significantly longer than standard rubber components. This means you get a more consistent feel from your suspension over time, helping your truck handle better when you're maneuvering through turns, accelerating from a stop, or braking. The polyurethane construction also helps keep the suspension functioning properly, contributing to a more controlled ride over bumps and uneven surfaces.

This kit is designed to fit directly into the rear leaf spring mounts, making it a straightforward replacement for your old, worn-out rubber bushings. You'll notice an improved sense of control and durability from your truck's rear end after installation.
