How do revolver shackles work?
The Revolvers expand when the axle droops providing more flex. The shackles are also able to twist with the leaf spring. These shackles called “The Revolver” have super-flex charactoristics. The Revolvers operate by expanding when the axle starts to droop providing excellent articulation.
How does a rear shackle work?
Shackles exist at the rear end of each leaf spring within the suspension system . They connect the springs to your vehicle’s frame through an eye spring bolt. The suspension responds to the bump, and the shackles allow the springs to absorb the obstacle’s force instead of hitting the ground.
What are leaf springs and shackles?
A shackle is an integral component of the suspension system that attaches between the leaf spring and the vehicle frame. It allows for the leaf spring to work through length changes during suspension articulation. The leaf packs, or leaf springs, position and center the axle under the vehicle.

How can I make my leaf springs ride better?
The following steps can make a huge difference:
- Reduce the unsprung mass.
- Soften the suspension system.
- Change the wheels and tires.

- Eliminate the vibrations.
- Get new leaf springs.
