What Parts Make Up a Trailer Spring Suspension?

A typical trailer spring suspension is made up of several key components that work together to support the trailer’s load and provide stability:

• Front Hanger: The bracket that connects the front of the leaf spring to the trailer frame.

• Rear Hanger: The bracket that connects the rear of the spring to the frame.

• Center Hanger (on tandem/triple axles): Provides a mounting point for the equalizer.

• Equalizer: Balances the load between axles in multi-axle setups.

• Shackle Links with Bolts: Provide movement and flexibility between the equalizer and leaf springs.

• U-Bolts & Tie Plate: Secure the axle to the leaf springs.

• Leaf Springs: Absorb road shock and support the trailer’s weight.

Together, these parts ensure even tire wear, smoother towing, and proper load distribution across the trailer axles.
