The PS15D Single Leaf Parabolic Trailer Spring is a heavy-duty, corrosion-resistant suspension spring designed for boat, box, utility and general-purpose trailers. Manufactured from a single tapered parabolic leaf, the PS15D is 45mm wide with a maximum thickness of 15mm and is rated at 1000kg per pair. Its Dacromet finish provides additional corrosion protection, making it particularly well suited to boat and marine trailer applications.

- Reduced inter-leaf friction compared with conventional multi-leaf springs
- Dacromet corrosion-resistant finish
- Particularly suitable for boat trailers
Advantages of the Parabolic Design
- Unlike a conventional multi-leaf spring pack, the PS15D uses a single tapered spring leaf. The varying leaf section provides the required spring characteristics without stacking several constant-thickness leaves together.
- This design reduces leaf-to-leaf friction, eliminates corrosion surfaces between multiple leaves and reduces the overall number of suspension components while providing progressive spring flex.
Suitable Applications
- The PS15D is suitable for compatible
- Boat trailers
- Jet ski and personal watercraft trailers
- Box trailers
- Utility trailers
- Camper trailers
- General-purpose trailers
- Single-axle trailer suspension systems
- Its Dacromet finish makes it particularly appropriate for trailers regularly exposed to water and marine environments.
Signs the Trailer Spring Needs Replacing
- Inspect or replace the PS15D where there is
- Cracking or fractures in the single spring leaf
- Permanent flattening or loss of camber
- Trailer sitting unevenly
- Excessive corrosion or deep surface pitting
- Worn or damaged spring-eye bush
- Distortion around the spring eye
- Damaged or displaced centre bolt
- Spring-to-axle misalignment
- Uneven tyre wear related to suspension alignment
- Visible deformation around the axle mounting area
- Because this is a single-leaf spring, any structural crack or significant deformation of the leaf warrants immediate attention.
