Energy Suspension HyperFlex Leaf Spring and Shackle Bushings
Vehicles with a leaf spring and shackle set up lean heavily on the springs to take the shock out of a bump. Not only does a leaf spring reduce the force of a bump that you feel, but it also evenly distributes the load across the chassis instead of the whole load pressing down on one point. Your ability to get to point A to point B without scraping the pavement is heavily dependent on the leaf spring and shackle bushings which mount the spring to the frame. Energy Suspension's Hyperflex polyurethane is a stronger material for the mounting points of a leaf spring and shackle. Polyurethane leaf spring bushings are able to handle the stress from the suspension and are not vulnerable to road grime. With Energy Suspension's polyurethane, you can protect your vehicle's ability to carry a load, and your bumpy free ride, for years to come.


Replacing the Faulty Rubber
O.E. leaf spring and shackles utilize a soft rubber bushing to mount the spring to the frame. The rubber is great for reducing the noise and vibrations from being transferred into the cab. Unfortunately, rubber bushings have a short lifespan. Once the rubber fails, due to wear and tear or road grime, a leaf spring's effectiveness is severely reduced. Meaning you will experience a very bumpy ride, the vehicle's ability to carry a load or tow is hindered greatly and you'll experience a loss of control.
Be sure to use Formula 5
A leaf spring bushing rotates a lot against the metal shell, so make sure you grease it well with Energy Suspension's own Formula 5 Bushing Lubricant. Using plenty of grease is the best way to ensure a long lasting part without any squeaking. If you'd like some extra grease just in case, pick up an extra 3 pack or an 8 ounce tube.

Energy Suspension 4.2138
starstarstarstarstar" Review 1 Year Later "
An absolute must have for any classic car restorations. High quality product that produces a better quality ride for a fraction of the cost of stock replacement bushings for pre-1979 era vehicles.

I put these all around in my 1968 Ford F-250 camper special. It took the mushiness out of the suspension. Some bushings may be a tight fit, but you just have to work it in by pressing out old bushing and pushing in new bushing with a big fat washer and a c-clamp. Hardest part is getting out old bushings. \nOne new bushing was very tight. So tight that the inner sleeve would not go in but I just drilled it out with a 3/4 inch drill bit, and then the inner sleeve went right in. It was on the spring eye end, which on my leaf spring, it wasnt exactly circular, that is why I figure it was tight. Worst case, you can shave it down a little bit. Editors Note: With older vehicles the bushing may have to be modified to make work. A vehicle 30+ years old the quality of manufacturing parts is not what it is today.
