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 4.2134
starstarstarstarstar" Very easy to install once the factory ones were out. "
I had to replace all 4 factory spring hangers & 2 of the shackles due to them rusting badly. That part of the job was very tiring & took longer than it should have if I had a hoist but I didnt & had to use jack stands on the ground. Installing the bushings was no problem at all & things went back together great. I have also used these on my 1946 Ford pickup truck (hot rod) all over & it has had no problems.
