Trailer Slipper Leaf Springs

Built from high-strength alloy spring steel and manganese steel, the trailer slipper leaf springs are designed with a layered plate structure that delivers strong load-bearing capacity, excellent shock absorption, and high resistance to impact and wear.

Compared with conventional suspension components, the trailer slipper leaf springs use a sliding-type design that ensures smooth extension and compression, balanced force distribution, and reduced risk of fracture under long-term heavy-duty operation.

Customization options include:

• Number of leaf plates
• Arc curvature
• Overall length
• Installation spacing and specifications

They are widely used in:

• Freight trailers
• Agricultural trailers
• Engineering trailers
• Light truck chassis suspension systems

This structure is particularly suitable for long-term heavy-load and bumpy road conditions, maintaining stable performance even under frequent dynamic stress.

Our factory implements a combined inspection system of sampling inspection and full inspection, ensuring consistent product quality at every stage.

 

Each batch of trailer slipper leaf springs can be fully inspected (100%) before packaging according to customer requirements.

 

We also support third-party professional inspections on-site, with strict control over:

• Raw material quality
• Manufacturing process
• Finished product performance

This ensures only fully qualified products are delivered from the factory.
